The PTR (Printing Temperature Recorder), printing thermometer has been specifically designed to provide a cost effective way of automatically measuring and recording temperature and time at regular preset intervals. The PTR can save you time and money as it can log temperatures unsupervised overnight, weekends or during the normal working day.

The 4 channel PTR is housed in a robust ABS case and incorporates an easy to use keypad. The print functions can be operated from the keypad on the PTR to provide a printed record of the temperature measurements and the real time they were taken.

The PTR printing thermometer features an easy to read, LCD display with low battery indication, displaying temperature over the range of -100 to 299.9 °C with a 0.1 °C resolution, auto-ranging to 1 °C over the range of 300 to 1372 °C (type K thermocouple). It is available in either type K or type T thermocouple models.

The user, via the compatible software provided with the PTR, can programme high and low alarms for each of the four input channels, each channel can also be personalised with its own label (maximum 12 characters) i.e. machine 1, machine 2 etc.

The software also allows the user to personalise the printed ticket with a company name, address and logo. At the end of each day or week, an audit trail, in the form of a comma separated (.csv) or Excel (.xls) file, can be downloaded from the PTR. Each PTR is supplied with a USB lead, battery charger, two rolls of paper, protective silicone boot and software, all supplied in a carrying case.

The PTR is priced excluding probe. ETI offers a wide range of interchangeable type K thermocouple probes, Click HERE for details.ETI offers an extensive range of interchangeable thermistor probes, click here to view the range. The PTR is priced exclusive of probe.

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.
