The MGD-2002 Multi-Gas Leak Detector, using a common tracer gas, such as helium or hydrogen, can locate leaks in most pressurized systems with pinpoint accuracy.

Helium is non-polluting, non-reacting and safe to use, making it the ideal tracer gas when applied to critical systems.  In addition, the sensitivity of the MGD-2002 allows helium to be mixed with ambient air in large volume systems, further reducing the cost of use.

Convenient and easy to use, the MGD-2002 is designed for one-handed operations of all functions.  Equipped with a tactile membrane keypad, all selections are easily confirmed with a distinctive "click", and the backlit display can be viewed in all light conditions.  The MGD-2002 is supplied with a built-in headphone jack for use with the audio indicator.

The MGD-2002 is equipped with a rechargeable Ni-MH battery pack that provides over 8 hours of use per charge.  Operating life can be further extended with an additional battery, available as an accessory, that can be installed in seconds.  The MGD-2002 can also be recharged with the AC or car adaptors included in the kit.
