The Reference Plus thermometer is a high accuracy PT100 instrument that is supplied with a 5-point UKAS Certificate of Calibration. Each certificate indicates deviations from standards at various check points: -18°C, 0°C, +40°C, +70°C and +100°C.
Special ranges may be certified by arrangement with the ETI UKAS calibration laboratory.
In contrast to the standard Reference Thermometer (ord. #222-055), the Reference Plus Thermometer has got pushbuttons for the data hold and MAX/MIN memory functions.
Pressing the HOLD button the current reading can be "frozen" at the display.
Via the MAX/MIN button the max. and min. readings can be indicated. These readings are not deleted when the instrument is switched off, but they can be reset also via the MAX/MIN button.
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, or also with the Comparator.
The instrument measures temperature over the range of -199.99 to +199.99°C with a resolution of 0.01°C and an accuracy of ±0.05°C.
The unit features a simple on/off switch with low battery and open circuit 'Err' indication, when applicable.
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.
