The Metrix MTX 3297Ex (by Chauvin Arnoux) is the ideal TRMS digital multimeter for your electrical measurement work in explosive Ex zones (intrinsically safe, ATEX) such as in mines, in the presence of gas, or in the presence of explosive dust.

The Metrix MTX 3297Ex is approved and certified for the highest levels of risk.  It is an exceptional multimeter which meets the strictest requirements and is IP67 rated (liquid and dust-proofing).

It is a high-performance industrial multimeter compliant with the IEC 61010-2-033 standard for work on 1000 V CAT III / 600 V CAT IV electrical installations.

Key features include:

  • Voltage, current and resistance measurements
  • Audible continuity, diode test, etc.
  • Capacitance and temperature
  • TRMS AC+DC acquisition
  • 60,000-count display
  • Resolution from 1 μV for voltage and 0.01 μA for current
  • Min, MAX, Peak+ and Peak- functions
  • ΔX differential and ΔX /X relative functions
  • Low-pass filter for measurement on PWM signals
  • VLowZ low-impedance DC voltage in the presence of disturbance voltages
  • Unrivalled ergonomics and rugged design

A stand out feature for the Metrix MTX 3297Ex is that when used with Chauvin Arnoux SX-DMM software for PC (free to download),  the isolated optical communication allows real-time processing of the data, remote control of the MTX 3297Ex, upgrading and maintenance.
