  • -4 to 140 deg F storage temperature, 0 to 80 percent RH
  • 9 V, NEDA 1604A, IEC 6LR61 9 V alkaline battery power
  • 200 hr battery life (manometer only, backlight off), 12 hr (pressure switch testing at 27 percent pump speed, BL off, approximate - 2-1/2 in WC induced pressure without pump bleed accessory)
  • 15 minutes auto power off
  • Low battery indication
  • 0.01 in WC resolution
  • 17.4 psi maximum pressure
  • Compatible with dry, non-corrosive gases
  • Pressure ports, 2 connectors (P1, P2) for flexible tubing (4-1/2 mm to 8 mm ID)
  • Pump port, 1 connector (pump) for 5 mm (3/16 in) ID flexible tubing
  • Lead jacks - 2 banana plug jacks for testing open/close switch status
  • Correct pressure switch operation is integral to the safety of a furnace environment
  • SDMN6 is a dual port manometer that also accurately tests pressure switches by simulating a draft with an internal pump
  • Adjust the pump's speed to create a negative pressure (vacuum)
  • Red LED indicates when the switch closes, view the closing/opening pressures directly on the LCD
  • Dual port manometer measures +/- 60 in of water column, high enough for gas pressures
  • Check building pressurization with static pressure resolution of 0.01 in WC, view P1-P2 in the bottom line of the display for checking pressure differentials
  • Use the static pressure probes to check for a pressure drop across two points in a duct, is useful for evaluating a blower or finding airflow restrictions in the ductwork
  • +/- 1.5 percent FS at 32 to 122 deg F accuracy
  • Accuracy: +/- 1.5% FS
  • Includes: SDMN6 Dual Port Manometer and Pressure Switch Tester, ANC1 - Four Pocket Carrying Case, ASP2s - Static Pressure Probes, RMA316 - Pressure Tubes, Quick-Connect Leads, Hoses and Y-Splitter and Hoses with Brass Screw Fittings
