Calog-TEMP, now available from Instrotech , is a hand-held calibrator which is made for testing, measuring and calibrating all Thermocouple and RTD based systems. Its small size, rugged design, rubber protective boot, high precision, logging facility and long-lasting re-chargeable lithium ion battery pack makes it well suited to industrial field calibration.
Using the simultaneous, isolated, combination of Thermocouple or RTD sourcing and mA measuring it is possible to calibrate any Tc/mA or RTD/mA temperature transmitter. The mA measurement can be passive with a remote supply or active 4-20mA 2-wire with the Calog-TEMP generating the 24VDC loop supply.
The accurate mA measure and source on the calibrator allows it to be used for all mA loop testing and instrument calibration. For temperature monitoring over time Calog calibrators may be set in trend mode with a selectable timebase to graph a temperature profile. This is ideal for testing ovens or for optimising PID temperature controllers. Data may be logged to the removable SD card in CSV format, with user-selectable data fields and timebase.
