Therma 20 Plus Waterproof Thermometer is housed in a robust ABS enclosure to prevent water ingress during use, submersion, or wash down. With a waterproof rating of IP66/67, the Therma 20 Plus is ideal for harsh environments where even the probe connection needs to be waterproof.
Therma 20 Plus probes are configured with a Lumberg watertight screw-locking connector to keep the probe securely connected and waterproof. Select from any of our Thermistor probes and the Therma 20 Plus will measure the correct temperature automatically.
With thermistor probes the Therma 20 Plus delivers system accuracy of ±0.7°F (±0.4°C) or better*. This includes all meter, probe and interchangeability errors. Change out to a different thermistor probe later and you'll still be within spec. With thermistors, the Therma 20 Plus reads from -40 to 302°F depending on the range of the probe itself.
Each Therma 20 Plus ships with a NIST-Traceable calibration certificate that ensures that each unit was hand built and tested in the UK.
For added convenience, the Therma 20 Plus includes a Min/Max feature that allows high and low readings to be stored, a reading hold feature, and a backlight for use in hard to see locations. With a battery life of 10,000 hours, the Therma 20 Plus will never need a battery change.
If you're looking for a rugged meter, this is the unit for your toolkit. You won't find a better value with this level of performance!
