Test Gauge, Stainless Steel - 332.30, 333.30
Brand: WIKA Alexander Wiegand SE & Co. KGThe model 33x.30 high-quality test gauge has been specifically designed for increased safety requirements during highaccuracy pressure measurements and is suited for calibration tasks. With an accuracy class of 0.6 %, the Bourdon tube pressure gauge is suitable for testing industrial type pressure gauges or for precision measurement in laboratories. Optionally, an accuracy class of 0.25 % is possible for pressures
≤ 400 bar.
Features- Safety pressure gauge with solid baffle wall designed in compliance with operational safety requirements of EN 837-1.
- All stainless steel construction.
- Knife edge pointer for optimal accuracy of reading.
- Wear-resistant precision movement of stainless steel.
- Scale ranges up to 0 ... 1,600 bar.
