MANOMETER
The Series 1211 Slack Tube
®
Manometer is as accurate as the nest laboratory

cover a wide range of pressure readings from 4-0-4 inches up to 60-0-60 inches.
The Model 1212 Gas Pressure Kit in comes supplied with a 1211-16 Slack Tube
®
Manometer, carrying case, necessary tubing, and connection ttings for checking gas
pressures in virtually all gas appliances.

• Rolls up for easy storage and transport
• Over pressure safety traps to prevent loss of uid due to over range pressures or
surges in pressure
APPLICATIONS
• Filter monitoring
• Duct static pressure for setting damper position
The Series 1227 Dual Range Flex-Tube
®
U-Inclined Manometers are versatile, low
cost manometers that can be used to read high-range pressure on the right leg or
as an inclined manometer to read low-range pressure on the bottom leg. It is made
of a sturdy, clear plastic and offers direct readings as a U-tube or an inclined gage.
Magnetic clips are attached to the unit to hold it in position on any steel duct surface
and instructions are conveniently printed directly on the scale.
FEATURES/BENEFITS
• Reads 0 to 16 in w.c. as a U-tube and -0.20 to 0 to 2.6 in w.c. as an inclined gage
• Clear, shatterproof indicating tube provides overpressure protection
• Black markings on a stark white scale for positive denition
APPLICATIONS
• Fan status
