Features

The Metrix MTX3297Ex digital multimeter is an advanced tool designed for professionals who need precise measurements in demanding and potentially hazardous environments. This device is certified to comply with the European Directive 2014/34/EU for use in explosive atmospheres (ATEX), ensuring safety and accuracy in industries such as oil, chemical, pharmaceutical, cosmetics, and mining.

Key Advantages of the Metrix MTX3297Ex Multimeter:

ATEX/IEC Ex IIC certification (gas) 0, 1, 2 and IIIC (dust) 20, 21, 22, as well as certification for M1 mining, enabling safe use in various industrial settings.
Precise measurement with TRMS AC+DC acquisition, ensuring accuracy in all conditions.
Large 5.7’’ digital display with 60,000-count resolution, making data easy to read in any environment.
100 kHz bandwidth and high resolution of 1 µV in voltage and 0.01 µA in current, perfect for detailed measurements.
Clear terminal strip indications to minimize connection errors.
Safety certifications outside ATEX zones: 1,000 V CAT III and 600 V CAT IV.
IP67 protection, resistant to water and dust for enhanced durability.

Measurement Capabilities:

The MTX3297Ex offers a wide range of measurement options, including:

Voltage and current (AC/DC)
Resistance, including continuity and semiconductor junction tests
Capacitance
Frequency with duty cycle and pulse width
Temperature
Current measurement using a clamp, with selectable input/output ratio

Advanced specific measurements include low-impedance AC voltage (VLowZ) to eliminate stray signals and a low-pass filter for PWM signal analysis.

Support Functions for Analysis and Diagnostics:

Recording functions for Min, Max, Peak+, and Peak- values.
Differential analysis with ∆X and ∆X/X functions.
Duty cycle and pulse width measurement.

Additional Features:

Designed and manufactured in France, ensuring high-quality standards.
3-year warranty, providing a secure and long-lasting investment.
Compatibility with SX-DMM software, allowing data transfer to a PC for in-depth analysis, available for free download.

The Metrix MTX3297Ex digital multimeter is an essential tool for professionals working in challenging environments who seek superior performance without compromising safety or compliance. Ideal for maintenance and troubleshooting, both in and out of explosive-risk zones.

What is ATEX?

ATEX is the abbreviation for “ATmosphères EXplosives” (Explosive Atmospheres). At the same time, it refers to a safety standard, a set of European Union directives that regulate all equipment installed in potentially explosive atmospheres (both gas and dust).

Directive 2014/34/EU (formerly known as 94/9/EC): This directive refers to equipment and protective systems intended for use in explosive atmospheres. It includes product certification and establishes the essential requirements that manufacturers must meet to ensure the safety of this equipment.
Directive 1999/92/EC (also known as "ATEX 137"): This regulates the safety of workers operating in zones with explosion risks. It defines the employer's responsibilities, such as classifying hazardous areas and adopting measures to reduce or eliminate the risk of explosions.

ATEX harmonizes various technical and legal requirements at the national level in Europe to ensure a very high level of safety.
The objective of Directive 2014/34/EU is to allow the free trade of ‘ATEX’ equipment and protection systems within the EU, eliminating the need for separate testing and documentation for each member state.

How is a potentially explosive atmosphere defined according to ATEX?

An explosive atmosphere is a mixture of flammable substances in the form of gases, vapors, mists, or dusts with air under atmospheric conditions, where, after ignition, combustion spreads to the entire unburned mixture.
An atmosphere that could become explosive due to operational conditions is called a Potentially Explosive Atmosphere.

Classification of explosive atmospheres

	Category	Atmosphere	Zones	Presence of Explosive Atmosphere
Group I (Mining Industries)	M1	Gas and Dust	Equipment will be energised
	M2		El equipo será desenergizado
Group II (Surface Industries)	1	Gas	0	Always
		Dust	20
	2	Gas	1	Occasionally
		Dust	21
	3	Gas	2	Rarely
		Dust	22

Areas of ATEX application

ATEX applies to industries that work with gases, vapors, dust, or flammable materials, such as sectors like:

Petrochemicals
Refineries
Mining
Chemical industry
Food industry (in cases of flammable dust)
