useCL541-PLUS calibratorYou can check and calibrate all thermocouple instruments and measure thermocouple sensors. Automatically indicate the connections on the display screen for easy connection. Enter the store, factory, or site carefree. It adopts rubber sleeve and sturdy thin switch protection. Even in dark areas of plants with backlit displays, it is easy to operate. Stop carrying millivolt power supplies and thermocouple meters, you can calibrate directly at temperature (° C and ° F).

CL541-PLUS calibratorCan be used in conjunction with your T/C, including J, K, T, and E types. The adjustable digital potentiometer "DIAL" can quickly set any value within 0.1 ° C and store any three temperatures for instant calling. Quick calibration through automatic output step by step. Select steps 2, 3, 5, 11, and 21 to automatically increase the output by 100%, 50%, 25%, 10%, or 5%. Select the step times that match the system, which are 5, 6, 7, 8, 10, 15, 20, 25, 30, and 60 seconds, respectively. Directly connected to the smart transmitter, PLC， Thermocouple inputs for controllers and multi-channel recorders, and verify their outputs or displays. Measure and eliminate any faults in the thermocouple sensor connection, and locate any broken or high resistance connections. Connect sensors,CL541-PLUS calibratorThermocouples that automatically measure C or F degrees.
