Questions & Answers

Frequently Asked Questions (FAQs)

Find answers to common technical queries regarding specifications, selection, calibration, and delivery.

Standard gauges use brass internals which corrode rapidly in contact with ammonia, acids, sea water, or sulfur compounds. All-SS gauges feature SS 316 wetted parts that prevent corrosion, scale build-up, and premature instrument rupture.

Yes, our SS gauges are rated IP65/IP66 weatherproof with neoprene rubber gaskets that seal against dust, driving rain, and corrosive coastal saline spray.

Yes, we supply specialized SS 316L and Monel wetted gauges compliant with NACE MR0175 for sour gas (H2S) applications.
