The Reference thermometers are precision PT100 instruments delivering high accuracy and come with a 5-point UKAS Certificate of Calibration. This certificate outlines deviations from standards at key checkpoints: -18, 0, 40, 70, and 100 °C. Special ranges can be certified upon arrangement with the ETI UKAS calibration laboratory. Designed for comparison checks of thermometer and probe calibration, these instruments operate within a temperature range of -199.99 to 199.99 °C, offering a resolution of 0.01 °C and system accuracy of ±0.03 °C (-49.99 to 149.99 °C) and ±0.1 °C (-150 to 200 °C). With a straightforward on/off push button, they include an open circuit 'Err' and low battery indication when applicable. The Reference Plus thermometer, featuring a max/min and hold function, enhances the Reference thermometer's capabilities. Equipped with a permanently attached, high-accuracy probe housing a 1/10th DIN PT100 sensor, measuring Ø3.3 x 130 mm, it comes with a one-meter PVC lead.
