We are using Pfeiffer Vacuum Helium Leak Detector to check the leak in various vacuum systems. This is a microprocessor-controlled leak-detecting equipment. All the processes in the instrument are controlled automatically. Leak detection in vacuum and sniffer mode is possible by this equipment. HLT 560 leak detector is having wireless remote control facility. Which is highly useful in leak detection of a large vacuum system.

RC 500 WL remote control


 The RC 500 WL remote control operates the leak detectors SmartTest HLT 560 remotely.

 It is accommodated in a robust housing the shape of which enables ergonomic working. Magnets on the underside of the unit enable it to be attached to horizontal or vertical metal surfaces.

 Remote operation works over a distance of 100 m, depending on the reception conditions. The integrated rechargeable battery enables over 8 hours of operation, depending on the battery level.

 The leak rates can be displayed in digits or in a curve on the colour display.

 Measured values of up to several hours of recording can be stored in an internal memory. The data storage interval is adjustable. The data can easily be downloaded to a USB stick via the integrated USB interface to save it

 An internal trigger can be set to provide a warning if the limit leak rates are exceeded. An optical warning is shown on the display and an acoustic warning signal with variable pitch proportionally to the leak rate is sounded on the integrated loudspeaker or the connected headphones.
