ETI Thermapen 3 Digital Thermometer with Choice of Probe Type Details

Note: this digital thermometer is supplied with your choice of surface, penetration or air temperature probe. Please select a version using the dropdown box when placing an order (probes are fixed and not interchangeable).

The ThermaPen can only measure temperature in Celsius (°C).

ETI's Thermapen 3 is a reliable, high accuracy digital thermometer which can be used to measure the temperature of pipes, bearing, hotplates etc (using the surface probe), the temperature of liquids and semi-solid materials such as food (using the penetration probe) or is also suitable for measuring air temperature in offices, labs etc (using the air probe).

Using the Thermapen 3 is simple - just fold out the stainless steel probe and start testing! When not in use, the probe folds back into the body of the thermometer for easier storage.

This digital thermometer can measure temperature from -49.9 to 299.9°C with resolution of 0.1°C or 1°C (selectable by the user) and accuracy of ±0.4°C. Results are shown on a 14.3mm LCD screen which is built into the side of the thermometer.

Using the Thermapen 3 in applications where it might get wet or come into contact with food? An ergonomic rubber seal minimises the risk of ingress from water, dust or food, while ETI's Biomaster additives reduce the growth of bacteria, preventing contamination (the case is also washable).

Supplied as standard with a 2 year guarantee from ETI.
