The PHP 602 is a high accuracy, dual input thermometer suitable for use with RTDs. If a large number of probes already exists in the data base, the user can at anytime, Resistance measurement (1)................ | create new linearisation tables and the metrological parameters (correction versus standards, serial numbers, names, calibration dates ...) are stored in the memory. | Thanks to these functionalities, PHP 602 is perfectly designed for accurate probes calibration using comparison method and studies of temperature phenomena. | ||||||||||||||
