Major Tech MT993 Multifunction Loop Calibrator

The Major Tech MT993 is a multifunction loop calibrator with dual independent channels for sourcing and measuring different signals at once. It sources and measures voltage (0–24V), current (0–24 mA) and frequency (0–9999 Hz), with a real-time curve display that tracks signal changes and a PWM output with independent frequency and duty-cycle control.

A 2.4-inch high-definition TFT with adjustable backlight gives clear readings anywhere, and a 3000 mAh rechargeable lithium battery delivers up to 26 hours of standby — ideal for PLC and loop testing in the field.
