ASF Pressure Tester Type VDM 300 R

Application

For testing of switching values of leak detection equipment or other pressure/vacuum devices.
The measured values can be displayed in: bar , mbar , kPa , mmHg , psi
To measure the switching values of the leak detector a suitable hose must be plugged on the corresponding input (+ = positive pressure, or - = negative pressure), depending on the pressure/vacuum ratio. The other end of the hose is plugged onto the measuring port of the leak detector.
Display: 2 four-digit LCD displays
Power-Off-Function: The unit turns off automatically after a set delay time.
Controls: Membrane keyboard
Interface: Can be connected to a PC with an optional interface converter (accessory)

The VDM 300 R must not be used in hazardous areas!

Operating Conditions

The VDM 300 R is not suitable for leak detection systems with an operating pressure of more than 2 bar.
The leak detectors or pressure devices must feature the appropriate connections.
The user's manual of the VDM 300 R must be observed.
The tester is supplied in a carrying case. Content is the VDM 300 R, about 30 cm sampling line, battery, and lanyard for the tester.
The leak test scoreboard and functional checks listed in the technical descriptions are to be observed.
