ETI Therma Differential Thermometer
Manufactured in the UK, the thermometer combines accurate measurement with a durable IP66/IP67-rated waterproof housing, making it suitable for regular use in demanding working environments.
Supplied with surface and penetration probes, the instrument provides the flexibility to measure temperatures across different applications, while its compact, ergonomic design makes it easy to use on site.
Measure Two Temperatures Simultaneously
Dual K-type thermocouple inputs allow two temperature probes to be connected and monitored at the same time, making the instrument particularly useful where temperatures need to be compared at different points within a system.
This provides a convenient solution for engineers carrying out temperature checks across heating, cooling and process systems, without requiring separate thermometers.
Designed for Easy On-Site Measurement
The ergonomic handheld design allows comfortable one-handed operation, while the large backlit display provides clear visibility in different working conditions.
Additional measurement functions include:
- Minimum temperature
- Maximum temperature
- Hold function
Together, these features make it easier to capture and review temperature measurements during routine inspection and maintenance work.
Robust & Waterproof Design
Designed for professional field use, the thermometer features a durable ABS housing with an integrated rubber seal.
With an IP66/IP67 protection rating, the instrument is protected against water and dust ingress and is well suited to demanding industrial and water treatment environments.
A protective soft carry case is also supplied for convenient storage and transport between sites.
