Precision Flow Test Kit 843
(2 Gauge Test Kit)

Rugged (2) gauge medium duty portable flow test kit (Models 831 & 841). This kit is equipped with two differential pressure gauges     with complimentary dials ranges, enabling it to cover a broad range differential pressures and accuracies;

Model 831, 0-5″ H2O to 0-9.9″ H2O ±5% / 0-10″ H2O to 0-400″ H2O ±3/2/3% full scale (ascending).

Model 841, 0-50″ H2O to 0-400″ H2O ±5% / 0-15 PSID to 0-100 PSID ±3/2/3% full scale (ascending).

Both gauges are protected against over-range to the maximum working pressure of the test kit. While primarily used for balancing HVAC systems it has numerous other applications which include but are not limited to: checking pump performance, checking pressure drop across filters, leakage, etc.
