Resolution: 0.1°C (0.2°F)
Field of View : approx 12:1
Response Time : approx 0.5 s
Accuracy : ±2°C (4°F) or ±2% of reading – a needle valve and a reverse free-flow
check valve connected in parallel.
– It restricts the flow rate in one direction
– While allowing the air to flow freely in the other direction.
- e) Pressure Gauge (digital high range)
To Provides a direct reading of the pressure in one of many convenient
measurement units. It features two
interconnected pressure ports, and is equipped with a mounting bracket for simple
installation on the workstation.
