ETI 271-302 3002 Dry-Well Heat Source Calibrator

What is the ETI 271-3002 3000 Series Dry-Well Heat Source Calibrator?

The ETI 271-3002 3000 Series Dry-Well Heat Source Calibrator is a compact, plug-in heat source designed for UK electricians, HVAC engineers and instrumentation technicians who need a straightforward way to verify the accuracy of digital thermometers and temperature probes. Lightweight and easy to operate, it is well suited to routine temperature checks during commissioning, servicing and maintenance work.

Covering a temperature range from 33°C to 250°C, the 271-3002 provides stable and repeatable performance without the complexity of liquid calibration baths. Simply power the unit, set the required verification temperature using the front panel controls and insert your probe into the appropriate well. Once stabilised, the probe reading can be directly compared to the calibrator display to identify any measurement error.

Which probes does the 271-3002 support?

The 271-3002 model is designed to accept a wider range of probe diameters, making it suitable for technicians working with multiple sensor types. It accommodates Ø3.3 mm, 4.76 mm, 6.35 mm and 9.6 mm probes, covering many of the slim and larger probes commonly used in electrical testing, HVAC commissioning and process monitoring. This flexibility allows multiple instruments to be checked using a single, compact calibration source without the need for adapters or additional equipment.
