Monster Meter Differential Gauge, 0.3% Accuracy Rated

The Monster Meter™ is a required component of In-line Pitotless Nozzles Kits.  This item comes with the INPN kits and can be purchased as a replacement.

The Monster Meter features smart functions like real-time GPM display, an intuitive user interface with pre-programmed device selection, and test data storage/recall capability.

  • With real-time GPM you will streamline your tests by eliminating the need to cross reference PSI to various flow charts or do any mathematical calculations.
