The Crystal Engineering m1M 3000 PSIG digital pressure gauge provides users with a 0.25% of reading accuracy over a wide temperature range.
Specifications
ACCURACY – 3 YEAR RECOMMENDED CALIBRATION INTERVAL
0 to 20% of Range:
±(0.05% of Full Scale)
Includes all effects of linearity, hysteresis, repeatability,temperature, and stability for three years.
20% to 110% of Range:
±(0.25% of Reading)
All models indicate vacuum, but vacuum specification appliesto 300 psi / 20 bar / 2 MPa models only.
Vacuum:
±(0.5% of Full Scale*)
* Full Scale = -14.5 psig / -1 bar / -0.1 MPa
Not recommended for continuous use below -14.5 psi. Refer toXP2i-DP data sheet for gauges that are intended for continuoushigh vacuum use.
OPERATING TEMPERATURE
