Valcom VPG8 Series
(Semiconductor diaphragm-type for Low-Absolute pressure)
- Suitable as a secondary calibration device for bourdon pressure gauge.
- Lightweight, compact, high accuracy (±0.25%F.S.) and waterproof equivalent to IP65
- Pressure peak and fluctuating pressures (±) can be checked by the peak hold function.
- Traceability documents available separately.
- Battery-operated (AAA alkaline cells) type serves as a portable pressure meter. Easy to change batteries.
