Gas detection, gas warning and gas concentration measuring device for working in the ppm, LEL, and vol. % ranges.

The EX-TEC PM4 is suitable for use for gas detection, gas warning, and gas concentration. It is also utilized for dynamic and static measurements. The unit functions through basic operator guidance, which uses selections from DVWG applications. The device provides visual alarms and temperature compensated sensors.

Additionally, the device is designed with a corrosion-proof structure and stainless steel body. It features three keys for simple operation and alarm thresholds for each gas. The equipment is integrated with a menu for separate device configuration and an adjustable test gas protection. Also, it is manufactured with an EC examination certificate, for the passive explosion protection. For active explosion protection, it has secured a certificate of BVS 09 ATEX G 002 X.
