Ametek Jofra mAcal Loop Calibrator

Designed for sourcing and measuring mA signals, the Ametek Jofra mACal Loop Calibrator is an economical and easy-to-use calibration instrument specifically optimised for two-wire transmitter loops with 4 to 20mA signals.

The Ametek Jofra mACal Loop Calibrator can source and measure current up to 24mA to an accuracy of ±0.05% full scale. It can also measure voltage between 0 and 45V DC to ±0.5V DC. Readings are indicated on the large display, as are error codes for loop mismatch, reverse polarity, and over range. You can view results in milliamps (up to 0.001mA), per cent, voltage, and seconds; switch between mA and % readings at the push of a button. Additionally, the Ametek Jofra mACal Loop Calibrator’s keypad is labelled for easy operation and includes dedicated function buttons that provide quick access to step functions and loop supply power.

Finally, the Ametek Jofra mACal Loop Calibrator offers 200 hours of operating time from four AA batteries. The Ametek Jofra mACal Loop Calibrator is a simple-to-use, precise and cost-effective calibrator.
