ATEX Multimeter MTX 3297Ex – Unmatched Performance in Explosive Zones
The MTX 3297Ex is a high-precision ASYC IV series 60,000-point TRMS digital multimeter, designed specifically for use in potentially explosive Ex zones and is certified Ex/IEC Ex:
- IIC (gas): Zones 0, 1, 2
- IIIC (dust): Zones 20, 21, 22
- Mines: M1
This device meets the most demanding criteria for permanent use in all Ex zones. It measures voltage, current, resistance, capacitance, frequency, temperature, and diodes with high accuracy. Outside the Ex zones, it functions as a high-performance 1000V CAT III / 600V CAT IV industrial multimeter. The MTX 3297Ex comes with ATEX-specific batteries and fuse, and you can download the SX-DMM software for free from our website.
Chauvin Arnoux MTX 3297EX, Intrinsically Safe Multimeter (IP67)
The Chauvin Arnoux (Metrix) MTX 3297Ex is the ideal TRMS digital multimeter for your electrical measurement work in explosive Ex zones (intrinsically safe, ATEX) such as in mines, in the presence of gas, or in the presence of explosive dust.
The MTX 3297Ex is approved and certified for the highest levels of risk. It is an exceptional multimeter which meets the strictest requirements and is IP67 rated (liquid and dust-proofing).
It 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.
Key features include:
- Voltage, current and resistance measurements
- Audible continuity, diode test, etc.
- Capacitance and temperature
- TRMS AC+DC acquisition
- 60,000-count display
- Resolution from 1 μV for voltage and 0.01 μA 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
- Unrivalled ergonomics and rugged design
A stand out feature for the Chauvin Arnoux (Metrix) MTX 3297Ex is that when used with Chauvin Arnoux SX-DMM software for PC (free to download), the isolated optical communication allows real-time processing of the data, remote control of the MTX 3297Ex, upgrading and maintenance.
