## Description

The instrument can measure the air pressure of single pipe , or differential pressure of two pipes ,It is suitable for measuring of ventilation and air conditionsystems, and widely use for gas measurement, calibration and any trouble shooting of any gas pressure systems Product Details Measuring Range: ±20.68 kPa / ±2.999 psi , Accuracy: ±0.3% FSO (at 25 OC) Repeatability: ±0.2% (MAX±0.5%FSO) Linearity / Hysteresis: ±0.29%FSO Response Time : 0.5Seconds, Over Range Indicator : Err 0 , Under Range Indicator : Err1 Temperature : -40 to 80 c (-40- 176F) Operating Conditions : 0 to 50 C ( 32 to 122F) storage conditions : -10 to 60C ( 14- 140 F) Battery : 9V battery Dimension : 164X70X32 MM weight : 200g Package include: 1x manometer 2x Soft Tubes 1x manometer protective bag 1x Barb access fitting 1x instruction Manual 9V battery Temperature : -40 to 80 c (-40- 176F) Operating Conditions; 0 to 50 C (32 to 122F)

Review: Accurate satisfactorily! Good enough for fluid mechanics lab equipments. Only for gases. And connected appropriately, the pressure is safely carried by the air in the connecting pipes to this gauge ! Can rely on Pascal to read liquid pressures
Review: Bastante útil para medir perfiles de velocidad en función de la presión estática y absoluta, aunque el juego de conexiones que compré solo tiene el detalle de que los tubos pitot L no están perforados de la boquilla

## Questions & Answers

**Q: can the units be switched from psi to "WC?**
A: Yes I used mine for measuring LP gas pressures.

**Q: What is the thread size of the barb metal connector - 1/4 in. or 3/8 in?**
A: The hose Barbs appears to be molded into the housing, for the supplied 1/8" ID dia hose.

**Q: why are there 2 connector ports?**
A: Second port is for measuring differential pressure, not needed if only reading pressure, and there is a positive and negative.

**Q: Why does it read -.018"H2O without even taking the measurement? That would be quite an error.**
A: Because it hasn’t been “zero’d” yet.
