All TPI manometers feature temperature compensation to ensure reliable, repeatable measurements. Over-pressure protection prevents sensor damage due to inadvertent pressure spikes. Wide input ranges and high resolution increases versatility and performance.

SP620 Differential Pressure Meter

Dual input differential manometer with +/- 60 inH2O input range. Use with TPI Smart Probe App to display pressure.

Use the TPI app to display real time readings in numeric and graph format. Save readings to a CSV file. The app allows the customer’s information to be stored and a report sent via email!
