ETI 222-055 Reference Thermometer

The ETI 222-055 Reference thermometer is a PT100 high accuracy instrument which is supplied with a 5-point UKAS Certificate of Calibration.
The UKAS certificate indicates deviations from standards at various check points: -18 °C, 0 °C, 40 °C, 70 °C and 100 °C. Specific ranges may be certified by arrangement with the ETI UKAS calibration laboratory.
The Reference thermometer is ideal for comparison checking the calibration and accuracy of other thermometers and probes, when used in conjunction with a stable temperature heat or chill source. The instrument measures temperature over the range of -99.9 to 199.9 °C with a resolution of 0.1 °C and an accuracy of ±0.2 °C.
The unit includes a simple on/off switch with low battery and open circuit indication, when applicable.
The Reference thermometer is supplied with a permanently attached, high accuracy probe which has a 1/10th DIN PT100 sensor. The probe dimensions are Ø3.3 x 130 mm, this is supplied with a one metre PVC lead.
A comparator chamber can be purchased for use with the reference thermometer. This enables a probe to be inserted in the base for measurements used with Infrared thermometers.
