Multitest 720 twin
Automated computer-assisted twin tester with fully automatic pneumatic mask tighteners for static tests on masks
Why use Multitest 720 twin?
Offering the top quality and operator-friendliness typical of MENZL equipment testers, Multitest 720 twin allows you to efficiently and conveniently carry out all of the static tests that need to be performed on respiratory protective masks.
The twin tester features two fully automatic pneumatic tighteners for masks with five-point head harnesses. Two-point helmet masks can be docked and tested in combination with optional accessories. The mask tighteners make it easy to swap masks quickly and guarantee that they sit properly on the dummy head.
Since you can test one mask and, simultaneously, prepare another one for testing, you will be able to test a maximum of masks in a minimum of time. As a result of this and because it is capable of operating in an automated computer-assisted manner, Multitest 720 twin meets the highest demands in terms of efficiency, the quality of equipment testing and data documentation. What is more, it could not be easier to use: There is a joystick for adjusting the size of the dummy head. During mask testing, the feature-packed yet easy-to-use Equipment Management program, which we develop in-house, not only controls the execution of the automated test procedures but also guarantees the accurate and tamper-proof documentation of the data recorded by the pressure transducer, whose accuracy class is 0.5.
Testing two-point helmet masks
We offer a comprehensive range of optional accessories for testing two-point helmet masks, including a purpose-built stainless-steel mask holder that is a great help and time-saver, especially if you need to test many two-point helmet masks. In its default configuration, the mask holder is suitable for Dräger and MSA two-point helmet masks (Gallet system). Two-point helmet masks with a docking mechanism for AUER F200 helmets (Schuberth system) or Rosenbauer helmets can be docked by means of optional adapters. Installing and removing the mask holder is easy and does not require any tools.
Available models
Multitest 720 twin: Automated computer-assisted twin tester with fully automatic pneumatic mask tighteners for performing tests on respiratory protective masks.
Multitest 720 M twin: Has the same features as Multitest 720 twin but comes with built-in low-pressure gauges, making it possible to operate the tester manually and perform tests in a non-computer-assisted manner.
