The MTX 3297 is a digital multimeter designed and compliant with the applicable European Directive 2014/34/EU ATEX Explosive Atmosphere.
The MTX 3297 meets the constraints of use in industries such as the petroleum, chemical, pharmaceutical or mining industries.
The instrument meets the needs of electrical maintenance services: testing and intervention inside and outside all hazardous areas in explosive atmospheres, without sacrificing compliance or quality of measurements. The MTX 3297 complies with the IEC 61010-2-033 safety standard.
The cables comply with IEC 61010-031 for voltages up to 1000V in Category III.

Ergonomics
Designed in France, with resistant materials and maximum hardware and software safety protections, the MTX 3297 is recognizable in the environment thanks to its red overforming.
It fits in one hand and is easy to handle even when wearing personal protective equipment.
It allows a very comfortable use thanks to:
- Good measurement visibility with a large backlit digital screen (5.7 inches on 60,000 points) and 2 different views for each screen (multi-values).
- A design designed to facilitate field measurement with a digital keypad equipped with backlit function buttons that provide additional visibility into poorly lit areas.
- An overformed box that offers excellent grip.
- A secure terminal block with clear identification of connections to avoid any risk of error.
- A retractable stand for stable use.

Measures
The MTX 3297 offers precise measurements of current electrical quantities: current, voltage, resistance, diode, capacitance, frequency.
It allows precise temperature measurement using Pt100 or Pt1000 sensors.
Accurate, the MTX 3297 measures all types of signals whatever their appearance, even the most disturbed: effective measurement of AC and AC+DC TRMS.
Comprehensive, it includes analysis tools to help you quickly diagnose faults with just 1 button: time-stamped MIN/MAX/AVERAGE and PEAK surveillance to automatically record transient values and variations.
Measurement specifications worthy of a sample multimeter:
- VDC 0.05%, bandwidth 100kHz, bargraph with automatic center zero in DC and MIN/MAX or PEAK mode to monitor your variations.
- Direct measurement up to 10A and even 20A (30s max) and over 10A clamp meter function.

Supplied with 1 x 2 x 1.5 m straight-angle connector cable, 1 x measuring lead kit, 1 x quick start guide (in 18 languages) with link/QR Code for free download of the operating instructions, 1 x Ex safety data sheet, 1 x 4 x 1.5V AA/FR6 Li-FeS2 batteries (pre-installed in the device) in accordance with Ex.
