Pfeiffer Vacuum and Scitek MiniTest 300 vacuum leak detector

Pfeiffer Vacuum and Scitek have introduced the MiniTest 300, which is claimed to be the first vacuum leak detector with quartz window technology. What makes this device different is the helium through a quartz window sensor rather than a mass spectrometer.

Weighing only 5 kg, the product is suitable for mobile leak detection, eg, as part of service jobs. In combination with the wireless remote control operation of the RC 500 WL, even large facilities and vacuum systems can be tested for leakages by just one person. The detection limit of 5x10e^-7 mbar L/s enables its use for leak detection in industrial and scientific applications such as vacuum coating, vacuum furnaces, freeze dryers, industrial valve and chamber products, as well as basic high vacuum systems.

The unit operates at a working pressure of up to 200 mbar, while a traditional leak detector with a mass spectrometer as a helium sensor commonly requires working pressures below 20 mbar. The product does not require a vacuum pumping system, making it virtually maintenance free.

The device is equipped with two different leak detection functions. An existing leak is located as quickly as possible when in search mode. If the size of the leak needs to be measured, the measuring mode is used. All measurement data can be saved in the device’s remote-control system and stored on a USB stick for further use.
