Introduction
Constantly increasing demands with regard to the performance and operational safety of
respiratory protective equipment call for a sustained effort to continually optimize equipment
testers.
Combining pinpoint accuracy with utmost operator friendliness and a stylish design, the Menzl
“Multitest ND” tester meets all the requirements of state-of-the-art equipment testing.
The tester
The “Multitest ND” tester is suitable for testing respiratory protective masks and lung-governed
demand valves at low pressure. In its basic configuration, it can be used for performing tests
on pieces of normal-pressure equipment with round-thread connectors. Thanks to a wide
range of adapters (see
), it is also possible to test positive-pressure equipment as
well as different makes of chemical protective suits.
Features of the tester
One battery (type D cell) is required for operating the tester. A compressed-air supply is not
needed. Optionally, the tester can be powered via a 230V/1.5V mains adapter. The low
pressure for leak-tightness tests and functional tests is provided by the tester's built-in pump
and shown on the low-pressure gauge. Chemical protective suits get inflated via the filling
hose's push-button valve, which features a plug-in nipple that is compatible with the plug-in
safety coupling. The dummy head can be inflated with compressed air from either an SCBA
or a compressed-air supply line.
Scope of possible tests
- all leak-tightness tests, opening-pressure tests and closing-pressure tests
- all tests performed at low pressure
- all tests done with a suction pump or a pressure pump
