About the ETI 231-022 Differential Digital Thermometer

Measure the temperature from two different points at the same time with this digital thermometer from ETI.

Designed for use with type K temperature probes (including the 3 probes included with this kit), you can use the ETI 231-022 to measure in practically any temperature application by simply swapping out the probes as needed (additional different temperature probes are also available for purchase separately).

Temperature can be measured from either a single channel (T1 or T2) or you can display the differential temperature between both channels (T1-T2).

This digital thermometer is also fully waterproof and is rated to IP66 and IP67.

ETI Therma Differential Thermometer Key Features

• Dual-input thermometer - measure temperature from two points simultaneously
• Works with a wide variety of interchangeable type K temperature probes (sold separately)
• Ideal for HVAC work - measure the temperature drop across radiators or the temperature rise and fall of other objects
• Measure from each channel individually (T1 or T2) or measure the difference (T1-T2)
• Temperature measurements from -99.9 to 299.9°C with resolution of 0.1°C and 300 to 1372°C with resolution of 1°C
• Data hold function temporarily stores current values shown on the screen
• MAX/MIN mode calculates the maximum and minimum temperatures taken over a period of time
• Automatic power off helps to save battery life
• 7500 hour battery life on 3 x 1.5V AAA batteries
• IP66 and IP67 rated waterproof case
• 2 year guarantee from ETI
