Superfast Thermapen thermometer

The SuperFast Thermapen 3 thermometer incorporates a large digital display with a precise read-out of temperature over the range of -49.9 to 299.9 °C with a 0.1 °C resolution and an accuracy of ±0.4 °C. The resolution can be switched to 1 °C, if required, via a switch in the battery compartment. The thermometer will power off automatically after ten minutes, maximising battery life. This feature can be disabled if not required. For user manual, brochure and trim adjustment instructions - click the 'download' tab above

The casing is washable and includes 'Biomaster' additive that reduces bacterial growth and the ergonomic rubber seal minimises the risk of the ingress of water, dust or food. As well as being splash proof, it is still 'probably' the fastest reading contact thermometer on the market today. The true temperature of a product can be tested in three seconds.

Both low battery (icon) and open circuit indication are displayed, when applicable. Each Thermapen is powered by two lithium coin cell batteries with a minimum life expectancy of 1500 hours.

reduced tip, foldaway probe
The SuperFast Thermapen® 3 thermometer incorporates a reduced tip, stainless steel, Ø3.3 x 115 mm food penetration probe that conveniently folds back through 180 degrees into the side of the instrument when not in use. 

The response time of any thermometer is dependant on many factors, the mass of the sensing tip, heat transfer and, most importantly, the state of the substance being measured. With both air and liquid, agitation is crucial to rapid response. The ETI calibration laboratory has tested the Thermapen® in a stirred water bath with amazing results - the SuperFast Thermapen® reached 100% of the test temperature in just three seconds. Thermapen® is a registered trademark in the UK (2025607), EU (008449571) and the USA (3898535). It is also protected by EC Regd.Des.No. 001580473.

The Super-Fast Thermapen is as versatile as it is fast and accurate. Here's a few ways a Thermapen can make your life easier:


candySweet Thermometer

There's nothing quite like a batch of homemade treats to make your home smell warm and inviting. The Super-Fast Thermapen is perfect for any would be sweet maker who's putting together a plateful of caramels, toffees, or fudge.

Did you know letting your caramel heat up past 168°C turns it from light to dark? Or that the difference between peanut brittle and butterscotch toffee is only 5°C? With a Thermapen doubling as your candy thermometer, you'll never have to second guess your temperatures.

Baking Thermometer

From start to finish, the Thermapen can be an important part of your bread making process. Professionals suggest you use a thermometer to gauge the temperature of the liquid to which you add your bread yeast (it's perfect between 40-46°C).

Bread will rise best at a perfect ambient room temperature of 23°C. A quick wave of the Super-Fast Thermapen and you'll know if your room is ready. And, once your bread is baked, the Thermapen can help check the internal temperature for perfect doneness (77°C for richer doughs, and 93-98.9°C for leaner breads).


candyMeat Thermometer

The Super-Fast Thermapen removes the guess work from whatever you're cooking. No more cutting into a steak to see if it's done, or using your finger to test it. The Thermapen is perfect for any piece of meat, no matter the size, shape, or cut.

With a reduced tip and Super-Fast thermocouple meter, the Thermapen will tell you what's happening inside of your steak, roast, lamb chop, or pork loin. It's arguably the fastest, most accurate and most reliable thermometer on the market today.

Home Brewing

Home brewers know the importance of having a good digital thermometer! Controlling the temperature of actively fermenting wort can have a major impact on the flavor of the finished beer. Fermenting above a normal temperature range may produce excessive fruity-flavored esters or harsh-flavored fusel alcohols.

An instant-read thermometer like the Super-Fast Thermapen is perfect for monitoring the heating and cooling process of fermenting wort. The fast and accurate temperatures give you real-time readings so you'll never have to wonder if you're hitting your target brewing temperature.


candySteamed Milk

Different temperatures of steamed milk will give different flavors to Caffe Lattes or Cappuccinos. A Super-Fast Thermapen can help you monitor your milk and help you achieve a temperature that, in general, gives the best flavor possible.

Higher temperatures will be harder for the tongue to analyze and can result in burns that are not desirable. The best milk temperature for Caffe Latte and Cappuccinos is between 60-68.5°C.

Brewing Coffee

Perfect coffee starts with the perfect blend of coffee beans, water and heat. The Super-Fast Thermapen is ideal for giving you fast and accurate temperature readings so you'll know when you're brewing at a perfect 90-96°C (the optimal temperature for extracting the most flavor from the bean).

Not only that, but once your cup of coffee has been brewed, the Thermapen will help you monitor the pot to be sure it's served at a perfect 82-85°C.

What makes the Thermapen so fast compared to other thermometers?

The main reason is the professional thermocouple technology that we use instead of mass-produced thermistor technology. Thermocouples are recommended by the most food standards agencies for measurement of cooked meat products and thin portions. We also use a reduced-diameter needle tip on the probe. Comparable professional meters cost £140 to £300 for the electronics and a similar probe! 

How long should my Thermapen's batteries last?

Thermapen 3 batteries are rated for 1,500 hours of use. Thermapen 4 battery life is 3000 hours. In the battery compartment you can enable and disable the auto-off feature. The auto-off feature will extend the life of the batteries. See your owner's manual for details.

Will the Thermapen tell me when my meat is done?

Not exactly. Instead it (very quickly) tells you the actual temperature and you decide if that is "done". We can give you the guidelines for food safety but you should consult your favorite cookbooks, TV shows and recipes for advice not only on safe temperatures but the best cooking temperatures for flavour and texture. Also remember that individual preference is very important.

Where should I place the probe tip to see if it's cooked?

When testing if your meat is cooked, the coldest part will be the very center of the thickest portion. With larger foods, you can take quick readings with your thermometer in several locations to verify that the entire portion is done. If you are chilling a food, the center of the thickest part will be the last to cool.  Penetrate the food you are checking with the probe and place the very tip of the probe where you want to measure.

I've seen cheaper thermometers, why pay more for a Thermapen?

In use there's a big difference. Don't take our word for it. Check our reviews to read the many reasons written by others. Cheaper thermometers are limited by the technology that they use. These can be mass produced for just a few pennies to a few pounds. On the other hand, the Thermapen is hand-assembled and hand-tested in the UK and uses a professional thermocouple circuit design. This design costs more to make than cheaper, less capable thermometers.

Biomaster protection

Biomaster antimicrobial technology is incorporated in the majority ETI products during the manufacturing process, ensuring lifelong protection against the risk of bacterial cross contamination. As well as being harmful to health, outbreaks of food poisoning can damage brands, and the reputation of stores, food producers and restaurants.

The risk of food-borne contamination is widespread, existing in restaurants, bars, hotels, supermarkets, hospitals, schools, aircraft, cruise ships and your home. Anywhere where food is made, prepared or eaten.

Biomaster treated products have been proven to reduce the growth of food borne bacteria such as E.Coli, Salmonella and Campylobacter by up to 99.99%, so by choosing an ETI product with Biomaster additive, you are protected 24 hours a day, every day.

What is Biomaster?

Biomaster Antimicrobial Technology is the leading range of safe, effective and permanent additives for the control of harmful bacteria, making any surface cleaner and more hygienic for its entire lifetime.

Proven to quickly reduce bacteria by up to 99.99% Biomaster is an effective means of reducing the growth of MRSA, E.Coli, Salmonella Campylobacter, Legionella and over 50 other species.

Incorporated into the body material of your ETI product, Biomaster becomes an integral part of it, providing durable, lifelong protection against the threat of cross contamination. 

How does it work?

The active ingredient in Biomaster is silver. Silver has been used in its pure form for many centuries to prevent the growth of bacteria.

Incredibly durable, long lasting and highly active, when Biomaster is added during manufacture it is dispersed throughout the product casing, will not wash off and will last for its entire lifetime. Biomaster provides antimicrobial protection without allowing bacteria to develop resistance.


Biomaster has 3 different modes of action:

Silver ions bind to the cell surface;
This disrupts the cell and prevents cell growth.

The silver ions are attracted to the Thiol groups in the cell enzymes;
This prevents the bacterium producing energy.

Silver ions interrupt the cell DNA;
This prevents DNA replication and new cell formation.


The Biomaster 3 stage mode of action does not allow bacteria cells to develop resistance, making Biomaster future proof and highly resistant against antibiotic resistant species such as MRSA.
