Yokogawa CA71 Handy Multifunction Calibrator

Handy Multifunction Calibrator
CA71

The CA71 lets you handle regular tests on TCs, RTDs and various other types of sensors and instruments, as well as operation checks when a problem has occurred. By itself it can source signals for input to equipment, and check output signal from equipment. With the CA71, you don't need to worry about synchronizing operations with other setting devices. (TC and RTD measurement functions are CA71 only.)

● Simultaneous signal source and measurement capacity
● Wide array of useful functions
● Easy operation
● Online communication function
