More About this Item

Gauges are fully temperature compensated, so the accuracy is the same over the entire operating temperature range. All gauges are tested and calibrated inside environmental test chambers using computer-controlled pressure controllers. Unlike mechanical pressure gauges, M1 gauges have the ability to survive being dropped and subjected to large over-pressure events with no change in calibration.

Easy-to-read 5-digit display features large 0.66” H digits and a bright backlight. Water-resistant enclosure is a polyester/polycarbonate blend and has o-ring seal. The housing and included boot are compatible with many industrial fluids including Skydrol.® The pressure sensor is a piezoresistive silicon sensor with a permanent oil isolation system and integral filter.

Available in the USA only.
