Multitest ND ME


Computer-assisted equipment tester for performing static tests on full-face masks and lung-governed demand valves



Article number:330-396



Why use Multitest ND ME?

Featuring only four controls, Multitest ND ME makes it easy to efficiently and conveniently carry out all the static tests that need to be performed on full-face masks and lung-governed demand vales.

The tester is equipped with an electronic pressure transducer. It can, thus, be connected to a computer, which guarantees an outstanding quality in terms of equipment testing and data documentation. While Multitest ND ME is operated manually, data can be recorded and managed in a computer-assisted manner thanks to the feature-rich MENZL Equipment Management and Testing program. It is, however, also possible to use the tester without a computer and record data manually by taking the reading of its low-pressure gauge. The gauge has a zero-offset calibration screw.

Multitest ND ME comes with round-thread connectors for lung-governed demand vales and full-face masks. Adapters (sold separately) are available for all commonly used types of positive-pressure masks and positive-pressure lung-governed demand valves. The required levels of positive and negative pressure as well as the necessary flow rates for opening-pressure tests and closing-pressure tests are supplied by the built-in pump.

Full-face masks are strapped onto an inflatable dummy head for testing in order to guarantee a perfect fit. Two-point (HMC) masks can be tested using special accessories (sold separately) (see below).
