ETI 221-041 Therma 1 Industrial Thermometer

Note: The Therma 1 is not supplied with the probe needed for measurement as standard. You can buy probes separately (see below for information on probes and also to download a full probe guide document).

ETI's Therma 1 digital thermometer is suitable for use in practically any temperature application; this industrial-grade professional thermometer is designed for use with a wide variety of interchangeable type K thermocouple probes (sold separately), which can be used to test everything from food to air temperatures.

With the Therma 1, you'll be able to test temperature from -99.9°C to 1372°C. All measurements are highly accurate with an overall accuracy of ±0.4°C ± 0.1%.

This digital thermometer is extremely simple to use; just plug your probe into the thermocouple socket, switch on and start testing! There's just two buttons on the front of the thermometer; the first switches it on/off, while the second - the HOLD key - will temporarily freeze the current values shown on the screen, allowing you to easily jot down your results.

The Therma 1 also has the added benefit of exceptional battery life; using just 3 x 1.5V AAA batteries, you can expect the batteries in this thermometer to last for a minimum of 10,000 hours (that's 5 years!).
