Handheld Process Calibrator Frequency Current Voltage

Precision current voltage frequency calibrator is a hand-held process controlling signal calibration meter with high precision, high resolution and high reliability. It integrates output and measurement of V, mV, mA and Hz signals. This Volt mA calibrator has large liquid crystal display with clear reading, and it also has adjustable back light source and automatic shutdown function. The calibrator can be powered by DC power supply or AAA dry battery, which is more convenient to use. It is an ideal replacement of other brands Volt/mA Calibrator, Loop Calibrator, etc.
