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 models C.A 6522, C.A 6524 and C.A 6526 are simple-to-use insulation and continuity testers designed for industrial maintenance operations. They are particularly popular for use in planned periodic insulation tests on installations and equipment. This helps prevent incidents by detecting ageing and the premature deterioration of insulation characteristics.
