Midwest Precision Flow Test Kit 831 for 0-50” H20

This kit has no evidence of use. I purchased it as government surplus, and have not ended up using it. This is a current US made product with a replacement value of over $1250 USD plus tax and delivery. According to the manufacturer: 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, orfice plates etc.) Dials may be for reading differential pressure, or reading flow directly (not included).
