ETI 271-301 3001 Series Dry-Well Heat Source Calibrator

What is the 3000 Series Dry-Well Thermometer Calibrator?

The 3000 Series Dry-Well Thermometer Calibrators are compact, plug-in heat sources designed for UK electricians, HVAC engineers and service technicians who need to quickly check the accuracy of digital thermometers and temperature probes. Lightweight and easy to use, they provide a practical solution for routine temperature verification during commissioning, maintenance and fault-finding work.

Covering a temperature range from 33°C to 250°C, the 3000 Series delivers stable and repeatable results without the complexity of liquid baths. Simply set the target temperature using the front panel controls, insert your probe into the appropriate well and compare the reading directly on the display. With fast stabilisation and consistent performance, these dry-well calibrators are ideal for workshops, plant rooms and on-site testing.

Which 3000 Series model is right for your probes?

Each 3000 Series dry-well calibrator is designed to accept specific probe diameters, making it easy to select the correct model to suit your existing temperature sensors and thermometers. Choosing the right version ensures a secure probe fit, accurate heat transfer and consistent calibration results during testing.

The 3001 dry-well is designed to accept Ø3.3 mm, 4 mm, 4.76 mm and 6.35 mm probes, covering many of the slim and standard probe sizes commonly used in electrical testing, HVAC commissioning and general process monitoring. This makes it a practical choice for engineers and technicians who need to verify multiple instruments using a single, compact calibration source without additional adapters or complex setup.
