Digital Pressure Gauge is fully temperature compensated.

Press Release Summary:

Model M1 Digital Pressure Gauge provides 0.2% of reading accuracy over entire operating temperature range. Gauge is tested and calibrated inside environmental test chamber using computer controlled pressure controllers and can be used to measure vacuum. Available with protective thermo plastic boot, CE certified product can survive being dropped and subjected to large over-pressure events with no change in calibration.

Crystal Engineering Corporation Announces the Development of the M1 Digital Pressure Gauge

San Luis Obispo, CA - Crystal Engineering Corporation, a leading pressure instrumentation company, has developed the M1, a new digital pressure gauge that can replace several mechanical gauges. The M1 is easy to use and delivers precision and performance at an affordable price.

M1 gauges are rated in percent of reading - like deadweight testers - but unlike deadweight testers, they're not affected by ambient temperature (or local gravity). M1's are fully temperature compensated, so the accuracy is the same over the entire operating temperature range, and they can be used to measure vacuum. "Because the rating is "of reading" - one M1 can often replace three or more 0.25% mechanical gauges!" says Tom Halaczkiewicz, President of Crystal Engineering Corporation. The M1 digital pressure gauge has 0.2% of reading accuracy.

All M1 gauges are tested and calibrated inside environmental test chambers using computer controlled pressure controllers. They are CE certified and are manufactured under a ISO 9001 registered quality system.

"Our pressure equipment are very rugged. All M1's come with a protective thermo plastic boot," says Tom. The display is protected by a hard polycarbonate/polyester blend lens, and the sensor is all welded stainless steel. A replaceable filter in the sensor keeps out debris. Unlike mechanical pressure gauges, M1's have the ability to survive being dropped and subjected to large over-pressure events with no change in calibration. The housing and boot are compatible with many industrial fluids including Skydrol®

For over 25 years, Crystal Engineering Corporation has been producing innovative, portable pressure measuring equipment and software that are accurate, reliable and easy to use. Our gauges and calibrators are used to measure pressure, calibrate other pressure measuring equipment and diagnose the performance of equipment that depends on pressures within it or applied to it. Our products are used worldwide in a variety of applications including NASA space shuttle flights, the International Space Station, and by top race car teams. Crystal Engineering manufactures products that are CSA, ATEX and IECEx Scheme registered. For more information about Crystal Engineering, visit
