The AEMC MX 57EX is an intrinsically safe digital multimeter designed for use in dangerous or explosive atmospheres. This meter is considered a passive device without inductive or capacitive issues that are problematic in dangerous or explosive environments. This meter provides high functionality in a unique case designed for enhanced safety, reliability, ease-of-maintenance and protection from contaminants.

The meter is built into a rugged housing which provides a separate battery and fuse compartment to isolate the DMM's electronics from contamination. This meter offers a complete set of measurement ranges and is in compliance with international safety and quality standards to ensure a professional and reliable measuring tool.

The AEMC MX 57EX measures AC amps, AC volts, DC amps, DC volts, resistance, continuity (with beeper) and has a diode test function. The large and easy-to-read LCD features a 50,000 count digital display. The display features comprehensive user interface symbols, such as low battery, Min/Max/Avg and a 34-segment analog bargraph for easy trend readings. Accuracy is 0.025%. The meter is equipped with a data hold function that freezes the measurement for later viewing.

The AEMC MX 57EX intrinsically safe digital multimeter ships complete with:

  • Test leads (red/black)
  • 9 V alkaline battery
  • Hard carrying case
  • Manual
