The RayTemp 38 is a professional infrared, gun-shaped, non-contact thermometer with dual laser dot alignment. The thermometer incorporates a 50:1 optic ratio (target distance/diameter ratio), this enables users to measure small targets from a distance. The user stands a safe and comfortable distance from the target, points the thermometer at the surface to be measured, pulls the trigger and instantly reads the temperature. Ideal for measuring the temperature of any item that is difficult to reach. This enables the user to measure most surfaces accurately and quickly.

This infrared thermometer measures the surface temperature over the range of -59.9 to 999.9°C with a 0.1°C (-9.9 to 199.9°C) or 1°C resolution. The RayTemp® 38 incorporates an auto power off facility that turns the instrument off after 60 seconds, maximising battery life. This function can be disabled, if required. Each unit incorporates a clear, easy to read, backlit custom LCD display that indicates both the temperature and the emissivity. The thermometer features a four-button keypad, allowing the user to select the mode required, i.e. max, min, differential and average temperatures, view the max/min high and low alarms and adjust the emissivity from 0.1 to 1.0 in 0.01 increments (default set at 0.95).

The RayTemp® 38 is two instruments in one as it incorporates a thermocouple socket that will accept a type K thermocouple probe, click here for available probes. The RayTemp 38 is sold excluding probe

Each RayTemp® 38 is supplied in a FREE protective ABS carrying case. An optional strong magnetic holder is also available. The holder screws into the bottom of the thermometer's housing, allowing the unit to be mounted onto a metal surface for continuous monitoring.

Infrared thermometry is used widely in the following industries/applications:


Used to Monitor steam systems, boiler operations, and motor/engine cooling systems performance; detect hot spots in electrical systems, panels and motor bearings. Widely used in all types of industries such as food, veterinary, paper, rubber, textiles, glass, plastics, metals, gas/electric utilities, cement, tires, pharmaceutical, asphalt, roofing, electronics, carpet/floor covering, and many more.

Heating and air conditioning:

Monitor furnace and duct leakage; detect insulation breakdown; check ceilings, walls and floors for proper room temperature, heat loss and gain.


Food safety:

Fast and convenient screening tool for both cold and hot foods for Food Safety and HACCP. No contamination or damage to the product. Easily take temperature of products moving on conveyors or hard to reach places. Verify equipment performance sanitation and process temperature conditions. Scan cooling systems, refrigerated display cases, trucks and storage areas before loading or stacking.



Monitor plant temperatures for stress, monitor animal bedding to detect spoiling.

Fire Safety:

To detect hot spots in walls, floors, etc. after fire is extinguished.
