Description
The MTX 3297Ex is a digital multimeter which complies with European directive 2014/34/UE on explosive (Ex) atmospheres.
It meets the needs of electrical maintenance teams: tests and troubleshooting inside and outside any hazardous zones with explosive atmospheres, without sacrificing compliance or measurement performance.
Usable outside Ex zones (out of operation), whatever the industrial activity, the MTX 3297Ex is a communicating instrument offering optimum industrial performance. It is possible to record the measurements on a PC by means of the SX-DMM software available for download from our website free of charge.
