The MTX 3297Ex is a digital multimeter which complies with European directive 2014/34/UE on explosive (Ex) atmospheres. The MTX 3297Ex fulfils all the requirements related to the operating constraints in sectors such as:

  • the oil industry
  • the chemicals industry
  • the pharmaceutical industry
  • the cosmetics industry
  • mining, etc.

It meets the needs of electrical maintenance teams: tests and troubleshooting inside and outside any hazardous zones with explosive atmospheres, without sacrificing compliance or measurement performance.

Usable outside Ex zones (out of operation), whatever the industrial activity, the MTX 3297Ex is a communicating instrument offering optimum industrial performance. It is possible to record the measurements on a PC by means of the SX-DMM software available for download from our website free of charge.

Measurements

  • Voltage
  • Current
  • Resistance (continuity, semiconductor junction)
  • Capacitance
  • Frequency (duty cycle/pulse width)
  • Temperature
  • AC/DC current measurement with selection of the I/O ratio

 

Functions

Specific measurements:

  • VLowZ low-impedance voltage measurement in the presence of “stray” disturbance voltages.
  • Low-pass filter for measuring the PWM signal

Functions to help with analysis and diagnostics

  • Min, MAX, Peak+ and Peak- functions
  • ∆X differential and ∆X/X relative functions
  • Duty cycle and pulse width

Additional specifications

  • Designed and manufactured in France
  • 3-year warranty
