 The MTX 3297Ex multimeter is an ASYC IV series 60,000-point TRMS digital multimeter designed for use in potentially explosive Ex zones and is Ex/IEC Ex certified:

- IIC (gas) 0,1,2

- IIIC (dust) 20,21, 22

- Mines M1

The most demanding criteria for permanent use in all Ex zones.

This comprehensive intrinsically safe portable multimeter measures voltage, current, resistance, capacitance, frequency, temperature and diodes. Outside the Ex zones, the MTX 3297Ex is a high-performance 1000V CAT III / 600V CAT IV industrial multimeter. The MTX 3297Ex comes complete with ATEX-specific batteries and fuse.
