Valcom VHR3(G3) Series
Excessive High Pressure Transducer (High Accurate)
- Adoption of hastelloy C22 diaphragm offers high corrosion resistance.
- Diaphragm structure enables high accuracy measurement even in lower pressure range. (Non Linearity: ±0.2%R.C.)
- Atmospheric pressure reference and absolute pressure reference available.
- Highly leak-proof and can be used even at high vacuum.
