Portable helium leak detector

Portable helium leak detector provides accurate registration of the flow of helium up to 1^.10^-7 Pa^.m³/s (7,6^.10^-5 l^.micron Hg/s) when working in sniffer mode.

The leak detector has a mass of 0.32 kg, capable of operating from the internal battery up to 10 hours. Due to the minimal size of the channel the motion of the gas, the device provides the response time for the flow of helium less than 0.1 seconds and the recovery time after the measurement of flow less than 1 s. The device does not need time to prepare for the measurements, it is ready for leak detecting immediately after power on.

Portable leak detector has two levels of sensitivity that allows the operator to search for leaks certain flows. Mode low sensitivity can detect a leak of helium to 1^.10^-5 Pa^.m³/s, in high sensitivity mode 1^.10^-7 Pa^.m³/s.

As large stationary leak detectors, portable leak detector has the function of zero the He background, which serves to bind the concentration of helium in the premises to zero, and allows the inspection of the tightness of constant regardless of the level of helium near the object.

Portable leak detector equipped with a screen, where indicated, the quantitative value of the measured flow of helium. The flow is also displayed in graphical form. The measurement results can be displayed on the computer and saved. The device is indicator, does not require calibration in the bodies of metrological control. Periodic calibration is neccesary for the helium leak used by the operator of the leak detector as the reference flow.
