Metrix MTX 3297 EX Intrinsically Safe True RMS Multimeter

What is the Metrix MTX 3297Ex?

The Metrix MTX 3297Ex is an intrinsically safe True RMS digital multimeter designed for electrical and industrial maintenance in hazardous environments. ATEX and IECEx certification allows permanent use in specified explosive gas, dust and mining zones, making it suitable for industries including chemical processing, pharmaceuticals, power generation and mining.

 

High-Performance Electrical Testing in Ex Zones

The MTX 3297Ex provides TRMS AC, DC and AC+DC measurements with a 60,000-count dual display. It measures voltage, current, resistance, frequency, capacitance and temperature, with additional functions including MIN/MAX/AVG, Peak, relative measurement, a PWM low-pass filter and low-impedance voltage measurement.

 

How does the MTX 3297Ex stand out in everyday use?

Built for demanding industrial environments, the MTX 3297Ex combines intrinsic safety with an IP67 rugged enclosure, backlit controls and isolated optical communication. Outside explosive zones it is rated CAT III 1000V / CAT IV 600V, while dedicated Ex-qualified measurement limits allow appropriate electrical testing within hazardous areas.
