ETI Reference thermometers are high accuracy PT100 instruments that are supplied with a 5-point UKAS Certificate of Calibration. Each certificate indicates deviations from standards at various checkpoints: -18, 0, 40, 70 and 100 ℃. Special ranges may be certified by arrangement, please contact us for more information.

Benefits

• ±0.03 ℃/°F high system accuracy
• 5-point UKAS Calibration Certificate included
• supplied complete with high accuracy probe
• ideal for calibration comparison checks
• meets the European Standard EN 13485

The Reference thermometers are 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 instruments measure temperature over the range of -199.99 to 199.99 ℃ with a resolution of 0.01 ℃ and a system accuracy of ±0.03 ℃ (-49.99 to 149.99 ℃) ±0.1 ℃ (-150 to 200 ℃).

The units feature a simple on/off push button with open circuit 'Err' and low battery indication, when applicable. The Reference Plus thermometer incorporates the additional features of a max/min and hold function.

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