M1 Digital Pressure Gauge

The M1 is a affordably accurate digital pressure gauge. The M1 has an accuracy of 0.2% of reading, which  competes directly with mechanical gauges. Accuracy is not degraded by dropping, over-pressure, rapid pressure changes or temperatures between -10˚C and 50˚C.

One M1 gauge can replace up to five mechanical gauges with an accuracy reading of 0.25% of full scale.
