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
G¼B BSP European 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. Download brochure
Accuracy
20% to 100% of Full Scale: ±(0.2% of Reading).
0 to 20% of Full Scale: ±(0.04% of Full Scale).
Vacuum, for 2MPa (300 PSI, 20 bar, 20kg/cm2) and lower pressure gauges:
0 to -99.9 kPa (-14.5 PSIG): ±(0.25% of Full Scale), where F.S.: -99.9 kPa (-14.5 PSIG).
(Not recommended for continuous use at high vacuum.)
Overscale Limit Display will flash at 110% of Full Scale.
