Dwyer Slack-Tube 1211-8 Instrucciones Y Funcionamiento

Slack-Tube ® Manometer rolled up for easy handling
and storage.
Dwyer Slack-Tube
accurate as the finest laboratory "U" gages -
yet they are made to roll up compactly for easy
carrying and to withstand rough usage.
Simply unroll the
Manometer and set up to read static pressure,
vacuum, or differential pressure. Magnetic
clips hold it firmly to any steel surface or hang
it on a nail. Turn connectors one revolution to
open. When the pressure is imposed, add the
number of inches one column travels up to the
number of inches the other column travels
down. When reading is completed turn con-
nectors to seal columns, roll up manometer
into compact coil and tuck it away in its circu-
lar metal case or a tool box. No fluid lost. No
loose caps or inserts to lose.
Dwyer Slack -Tube
range of pressure readings from 4-0-4 inches
up to 60-0-60 inches. Use them in determin-
ing velocity and static pressures, for leakage,
fan and blower tests, calibrating control
devices, checking gas pressure and many
other applications.

exclusive molded nylon tubing connector
assemblies with rapid shutoff design in an
unbreakable molded top (see picture, page 2).
One turn counter clockwise and the instrument
is ready for use. Another turn seals the tubes
completely. Molded all-nylon construction
makes this assembly corrosion-proof leakproof
and practically unbreakable. Tubing connec-
tors extend horizontally allowing 360° freedom.
Tubes will not bend or pinch off.
All models have over pressure safety traps in
the top of both columns to prevent loss of fluid
due to over range pressures or surges in pres-
sure.
Slack-Tube ® Manometers are suitable for total
®
pressures to 50 psi and vacuum not exceeding
20˝ Hg. (10˝ Hg absolute). Can not be used
with 0.826 sp. gr. red gage oil;use only water
or mercury.
