Intelligent digital vacuum gauge Laboratory refrigeration system vacuum inspection vacuum gauge VMV-1 The VMV-1 uses Pirani #39;s professional vacuum sensors to accurately measure vacuum. In this way, the best information on dehumidification and foreign matter removal in the vacuum system can be obtained, and the state of the best refueling refrigerant can be obtained, and the vacuum system can be monitored in real time. Identify the use of vacuum pumps, etc. Maximum overload pressure: 72PSI/0.5Mpa Range: 0-10000Pa, 0-100.00mBar, 0-75.000mmHg, 0-75000Microns Resolution: 0.01 ( lt;10pa), 0.0001 ( lt;10mBar), 0.0001 ( lt;10mmHg).1 ( lt;30000 Micron) Measurement accuracy: 2-100Pa (degree ± 5%) Operating temperature: 0-50°C Battery Life: 45 hours (3pcs AA battery) not included Units: Pa, mBar, mmHg.Microns Refresh rate: 0.5 seconds Interface: 1 7/16-20UNF Sensor: Pirani sensor Automatic shutdown: 10 minutes Backlight: 20 seconds Beep Horn: 90 dB, closes after 10 seconds Weight: 125G Scope of application: Atmospheric environment
