The Crystal Engineering m1M 3000 PSIG digital pressure gauge provides users with a 0.25% of reading accuracy over a wide temperature range.
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 applies to 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 to XP2i-DP data sheet for gauges that are intended for continuous high vacuum use. | |
OPERATING TEMPERATURE | ||
Temperature Range: | -10 to 50° C (14 to 122° F) | Non-condensing. No change in accuracy over operating temperature range. Gauge must be zeroed to achieve rated specification. |
DISPLAY | ||
Screen: | 5 digits, 16.8 mm (0.66") high | LCD readable in sunlight with bright backlight. |
Display Rate: | 4 readings/second | |
POWER | ||
2 x AA: | 900 hours, typical | Uses 2 alkaline AA (LR6) batteries. Use of backlight reduces operating time. Extended battery life is keypad selectable. Do not overtighten rear cover when replacing batteries. |
Extended Battery Life: | 1 reading/15 seconds: 3,000 hours 1 reading/30 seconds: 6,000 hours 1 reading/60 seconds: 10,000 hours 1 reading/5 minutes: 25,000 hours 1 reading/10 minutes: 30,000 hours | |
