Brochure

Correct pressure switch operation is integral to the safety of a
furnace environment. The SDMN6 is a dual-port manometer that
also accurately tests pressure switches by simulating a draft with
an internal pump.
The SDMN6 allows you to test pressure switches the right way.
Adjust the pump’s speed to create a negative pressure (vacuum).
The red LED indicates when the switch closes. View the closing
and opening pressures directly on the LCD.
The dual-port manometer measures ±60 inches of water column,
high enough for gas manifold pressures.
Check building pressurization with static pressure resolution of
0.01”WC. View P1-P2 in the bottom line of the display for checking
the performance of a blower.
