MiniTest 300 portable 
helium leak detector is light weight, easily operated and provides superior performance. At only 5 kg, the ASM 300 is compact and easy to move around and is an ideal solution for maintenance applications. It has multiple interfaces including RS-485, RJ-25, Gauge, I/O D-Sub-9, Fernbedienung D-Sub 9.
The Pfeiffer MiniTest 300 has no backing pump. It uses a quartz window sensor for vacuum leak detection. The MiniTest 300 can work at a high inlet pressure of up to 200hPa and is not sensitive to water vapor. Data recording via a USB interface in the Remote control makes this user friendly for logging data. All functions of the detector can be controlled up to 100 meters away with the RC 500 WL remote control.
