The instrument is based on an air/gas blender in a heated box, a catalytic combustion chamber where is burnt the air/gas sample and a cell to measure the oxygen remaining after combustion..
The savings achievable through the use of the meters, the availability of near real time control signals, and the low cost of ownership compared with alternative measurement methods such as..
Those devices allow the detection of differents types of gases like CO, CO2, CH4, refrigerant gases etc. The instrument is very accurate and the detection is done by a capillary diffusion in the sensor.
The ZOA 100 oxygen analyzer model uses a gaseous diffusion micro zirconium oxide cell. This technique allows continuous or intermittent use with reduced maintenance..
