Crystal Engineering M1 Digital Pressure Gauge
The Crystal Engineering Model M1 digital test gauge boasts a 0.2% of reading accuracy over a wide temperature range. The m1 is affordable and extremely durable, replacing low cost mechanical gauges or cheap imported digital gauges. The M1 is available in ranges from 30 to 10,000 psig and ships with a factory test report and a blue rubber boot. For this price point, you will be hard to find a better more accurate digital pressure gauge than the Crystal M1. It's time to start thinking of replacing your mechanical fleet of pressure gauges with the m1.

Technical Specifications
ACCURACY
|
0 to 20% of Range:
|
± (0.02% of Full Scale)
|
Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.
|
|
20% to 110% of Range:
|
± (0.1% of Reading)
|
All models indicate vacuum, but vacuum specification applies to 15 psi, 30 psi, 100psi, and 300psi models only.
|
|
Vacuum:
|
± (0.25% of Full Scale*)
|
Not recommended for continuous use below -14.5 psi.
|
|
|
* Full Scale = -14.5 psig
|
Refer to XP2i-DP data sheet for gauges that are intended for continuous high vacuum use.
|
