TPI 621C3 8 Piece Dual Input Digital Manometer Kit

High efficiency gas and oil fired furnaces along with condensing boilers require a manometer with 0.001 inches of water resolution to make proper adjustments.

• Kit includes 621 dual input differential manometer, 2 A605 T fitting, 1 A774 tubing, 2 A776 static tip, 1 A791 adapter tube and 1 A908 carrying case

• 0.001 inH2O resolution at less than 40 inH2O; 0.01 inH2O resolution over 40 inH2O
• Enough range and resolution to perform low pressure and draft measurements on high efficiency gas and oil fired equipment.
• +/- 120 inH2O range, over-pressure protected to 200 inH2O
• Enough range for low side regulator adjustments and protection against pressure spikes
• Temperature compensated to ensure repeatable measurements
• Pressure measurement is not affected by ambient temperature
• Dual input differential
• Troubleshoot and setup two stage pressure switches
• Seven units of pressure: inH2O, mbar, KPa, PSI, mmH2O, mmHg, inHg
• Enables equipment adjustments to be made easily
• Trim mode to stabilize readings

Applications:

• Adjust appliance regulators
• Setting delivery pressures
• Leakage “shut-in” tests
• Replace messy U-tube manometers
• Test low pressure gas systems for leaks
• Regulator adjustments for pressure and lock-up tests
• Test pressure switch operation on a 2-stage gas furnace in both positive and negative pressures
• Measure furnace and boiler draft
