The digital thermometer/datalogger Labcal PRO from Labfacility is fully characterised for Pt100 sensors and all major thermocouples J,K,N,T,E,R,S and B. Stable automatic cold junction compensation with a rejection of 100:1 is incorporated for thermocouple ranges. Alternatively, external or manual referencing can be selected as required. Displayed values and user information are indicated on a bright clear OLED screen with diffused backlighting. Data can be displayed in °C, °F, K, Ω or mV as required. Nine front panel push keys, the only user controls, are used in conjunction with the display screen. Resolution is a user selectable 0.001 or 0.01 °C for Pt100 sensors and 0.1 °C for thermocouples. All computations are preformed digitally without drift. Overall stability is optimised by utilising components including high precision, expensive metal film resistor networks. There are four input ports, two for thermocouples and two for 3 or 4 wire Pt100 sensors. The instrument automatically recognises 3 or 4 wire configurations.
