The detector uses natural diffusion into electrochemical sensors with it's state of the art electronics and software to give reliable and repeatable readings. The casing is a rubber based special high strength material giving it an IP67 rating making it anti-slip, completely dust proof and water proof up to 1 meter. The sensor has inbuilt data logging which will timestamp the gas level readings and alarms. This data can be downloaded to a PC using the SGT IR Link for analysis. The gas detector can be operated continuously for two years without replacement and then can be safely disposed of.

|Lift Shaft Wells|
Oxygen sensors are often placed in lift shaft wells to measure the atmosphere prior to entry. Problems arise due to the pressure changes in the left shaft well due to the air movements associated with the lift.resulting in false alarms . There is also an issue associated with safe work permits for access into the lift shaft area when the oxygen sensor requires calibration or replacement. The GDA 4500 system uses a vacuum pump ( dc brushless) , a flow fail mechanism and a sensor to extract the gas via a 6mm ID tubing . The Nylon tube is fitted with a filter element to provide dust filtering and prevent mycological build up in the sampling line.
