Do more with less!

The M1 is a digital pressure gauge with 0.2% of reading accuracy. It 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 0.25% mechanical gauges with an accuracy reading of 0.2%.
