High Performance Helium Leak Detectors ASM 182 Series

There are several types of calibrated leaks, with or without reservoir, with or without valve, covering several leak ranges. All are based on permeable membrane technology. The choice of the appropriate external calibrated leak depends on the application requirements.

Most calibrated leaks last many years even though the helium is permanently escaping (the leak rate is very small in comparison to the amount of helium contained in the reservoir: yearly loss is indicated on the calibrated leak identification label). However, it is recommended to have every calibrated leak (with reservoir) recalibrated on regular intervals to validate its value: this is applicable for both internal and external calibrated leaks. Recalibration period of the calibrated leak depends on its leak rate value.

with 5 m cable length suitable for ASM 142, ASM 182 and ASM 192 series

The remote control is equipped with a magnet allowing the operator to place it on a magnetized surface. The operator can read the helium signal and has access to control keys such as cycle command autocalibration and auto-zero.

The multi-color remote control offers the choice from 3 different measurement units :

mbar.l/s and mbar.

Pa.m3/s and Pa.

Torr.l/s and Torr.

The remote control is delivered in standard with the ASM 192 series.

Spraying helium in order to detect a leak is usually very easy, especially if you need fast and rough detection.

Spraying helium could also become a technical challenge when you need to pinpoint very fine leaks, more so, when they are located in areas with difficult access.

The helium spray gun is an easy to use and multipurpose tool which allows you to work in various conditions of test:

• Multi standard: thanks to the 3 different adapters to be connected to the helium bottle (M 1/4 NPT, M 3/8G and M 1/8G)
• Multi purpose: thanks to the 2 nozzle lengths of 80 mm and 290 mm
• Standard leak mode: for quick and rough leak tests
• Fine leak mode.

The helium spray gun is provided with 2 standard needles wich allow the adjustment of the Helium flow at the outlet of the nozzle.
