Description
Product Summary
The NAVAC NMV1 is a compact digital micron vacuum gauge that uses a high-precision Pirani sensor to measure system vacuum during evacuation. It reads across a 0 to 75,000 micron range with ±5% of reading accuracy from 15 to 750 microns, the critical window for confirming system dehydration.
A digital display gives a clear view of vacuum conditions, and built-in alarms keep you informed without constant monitoring: the gauge buzzes when the preset vacuum target is reached and, if vacuum rises above the preset level during a decay test, buzzes rapidly and flashes the backlight to warn of a leak. At just 4.5 oz, it fits easily in any tool bag.
Key Features
- Pirani Sensor: High-precision vacuum sensor for accurate micron readings.
- Wide Range: 0-75,000 microns, with Pa, mBar and mmHg units available.
- ±5% Accuracy: From 15 to 750 microns at 68°F.
- Target Alarm: 90 dB buzzer sounds when the preset vacuum level is reached.
- Leak Warning: Rapid buzz and flashing backlight when vacuum rises above the preset level.
- Lightweight: Only 4.5 oz for easy carry and mounting on the manifold or hose.
