What is the ETI Therma 1 Industrial Digital Thermometer?

The ETI Therma 1 Industrial Digital Thermometer is a robust and easy-to-use thermometer designed for UK HVAC engineers and building services technicians carrying out temperature measurement, system diagnostics and commissioning in demanding environments. With a wide temperature range and high-resolution display, it delivers reliable readings across heating, ventilation and industrial applications.

Ideal for use with interchangeable thermocouple probes, the Therma 1 supports accurate temperature checks on pipework, air systems and plant equipment. It is supplied without a probe, allowing technicians to select the most suitable probe for their specific application.
