The two multi-function-instruments are outstanding for theri high accuracy of ±0,03°C. You can optional plug in Pt100 or thermocouple (type J, K, L, N, R, S, T), as well as probes for humidity and flow. The high precision makes them eminently suitable as reference instruments for testing subordinate measuring instruments in quality assurance laboratories or for checking temperature- critical processes. These instruments are frequently provided with a DKD calibration certificate.
