Series AT-2000 ATEX/IECEx Approved Magnehelic® Differential Pressure Gages
Magnehelic® Gage in Flame-Proof ATEX/IECEx Enclosure
The Series AT-2000 ATEX/IECEx Approved Magnehelic® Differential Pressure Gages combines the popular Magnehelic® line with a flameproof enclosure to extend usage to hazardous locations. This gage can indicate positive, negative or differential pressures and is accurate within 2%.
Attention: Check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous areas.
Please see Series 2000 for non-ATEX/IECEx approved.
Product Applications
