Reference Thermometers The Reference thermometer is a high accuracy PT100 thermometer that is supplied with a 5-point UKAS Certificate of Calibration. 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, see our dry-well calibrators. The reference thermometer measures temperature over the range of -199.9 to 199.9°C with a resolution of 0.01°C and an accuracy of ±0.05°C. The thermometer features a simple on/off switch with low battery and open circuit indication, when applicable.

Each calibration certificate indicates deviations from standards at various check points: -18, 0, 40, 70 and 100°C. Special ranges may be certified by arrangement with the ETI UKAS calibration laboratory.

The Reference thermometer is supplied with a permanently attached, high accuracy probe incorporating a 1/10th DIN PT100 sensor. The probe measures Ø3.3 x 130mm and is supplied with a one metre PVC lead.
