GasAlert Extreme

The GasAlert Extreme portable gas detector has been designed to be comfortable and durable. It is capable of monitoring for any single toxic gas such as O2, SO2, H2S (High Range), H2S, ETO, PH3, HCN, CO (Low H2), CO, NO, ClO2, NH3 (High Range), NH3, O3, Cl2, and NO2.

The device features accurate and secure datalogging and has support for numerous languages including English, Portuguese, French, Spanish and German.

Daily operation couldn’t be simpler given the straight forward on/off button operation. A field replaceable sensor and battery allow for device longevity and calibration is easy given the compatibility with the MicroDock II (test and calibrate) system.

Different accessories are available such as the Sampler Motorized Pump which provides remote sampling. The Pump is a useful accessory for those needed a pre-entry solution or those working in confined spaces.

Here at Australian Dynamic Technologies we have expert staff (backed with years of experience) ready to take your call and assist with any questions on gas detectors that you may have.
