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%.
- Enclosure is rated to NEMA 4, IP65
- Can be customized for specific vendor applications
- Battery life up to 3 years continuous use
- Bright backlit display
- G ¼ B BSP parallel fittings available
- Protective boot included

Applications
- Replaces ruggedized 0.25% mechanical gauges
- Basic digital pressure gauge
|
Included with every new M1 Digital Pressure Gauge is an A2LA accredited calibration certificate with test data recorded at 5 different temperatures - proving that it meets published specifications over the entire operating range. You won't get this kind of detailed report anywhere else!
Specifications
Specifications include all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.
