Description
Chauvin Arnoux MTX3297Ex ATEX approved multimeter
MTX3297Ex Comes Supplied With:
• MTX 3297 delivered fitted with 4 EX-qualified 1.5V lithium batteries
• 1 set of 2 x 1.5m straight cables and CAT IV 1kV test probes
• Quick Start Guide on paper in 18 languages with QR code to download the User’s Manual
• ATEX safety manual on paper
The MTX 3297Ex is a digital multimeter with a Zone 0 classification 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:
- Petrochemical Refineries: Certain areas within refineries, such as storage tanks, process vessels, or pipelines where highly flammable substances are handled, can fall under Zone 0 classification.
- Chemical Manufacturing Facilities: Specific processing units or storage areas dealing with volatile chemicals or solvents may be designated as Zone 0.
- Fuel Storage and Distribution: Underground storage tanks, fuel depots, or loading areas where flammable fuels are present can be classified as Zone 0.
- Pharmaceutical Laboratories: Laboratories that handle and store highly flammable or volatile substances might fall under Zone 0 classification.
- Oil Rigs – Certain areas within offshore rigs
| Type of atmosphere presence | Gas/Vapour Zone | Dust Zone | Instrument Categories |
| …permanently or for long periods in normal operation | 0 | 20 | 1 |
| …occasionally in normal operation | 1 | 21 | 1,2 |
| …accidentally, in the event of dysfunction or for a short time | 2 | 22 | 1,2,3 |
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 the Chauvin Arnoux website free of charge.
Ex certification has been adopted by the countries in the European Union and several other European countries.
IEC Ex certification, developed by the International Electrotechnical Commission (IEC), aims to harmonize and simplify the certification of equipment for hazardous zones worldwide.
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.

Outside explosive zones, the MTX 3297Ex 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.
High performance for reliable, accurate measurements whatever the type, shape and amplitude of the signal
• TRMS AC+DC acquisition
• 60,000-count resolution
• 100 MHz bandwidth
• 1 μV resolution for voltage, 0.01 μA resolution 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
When used with the SX-DMM software for PC, the isolated optical communication allows realtime processing of the data, remote control of the MTX 3297Ex, upgrading and maintenance.
