| Pressure range |
Gauge mode: 1.4 kPa to 7 MPa (0.2 to 1000 psi) gauge
Absolute mode: 1.4 kPa to 7 MPa (0.2 to 1000 psi)
Vacuum mode: -100 to 0 kPa (-14.5 to 0 psi) gauge (Vacuum pressure achieved depends on local barometric pressure) |
| Electrical power |
115/230 VAC, 50/60 Hz, 15 W |
| Temperature |
Operating temperature 15 to 28°C (60 to 82°F)
Storage temperature -20 to 70°C (-4 to 158°F) |
| Humidity |
Operating humidity 20–75% relative humidity, noncondensing; storage humidity 0–90% |
| Pressure medium |
High purity nitrogen or dry, clean air with less than 0.5 ppm hydrocarbon and less than 5 ppm H2O content, dew point less than or equal to -50 °C, and less than 50 micron particulate size. Although lower quality gas can be used, the frequency of piston/cylinder cleaning will increase. |
