Model 831 Precision Flow Test Kit

Sensitive yet rugged medium duty portable test kit. 

This test kit is equipped with a ±3-2-3% of full scale accuracy (ascending) diaphragm type differential pressure gauge. 

Ideally suited for applications where differential pressures of 0-5" to 0-400" H2O may be encountered. 

Popular applications are balancing heating & cooling systems, checking pump performance, leakage, checking equipment for excessive pressure drop (i.e. filters, balancing valves, averaging pitot tubes, orifice plates etc.) .

Dials may be for reading differential pressure, or reading flow directly, if ordered with a flow (square root) dial.
