Functional principle of the device
For CXHY measurement the device contains a high-capacity low-consuming optical sensor which
functional principle is based on the preferential absorption of infrared radiation by molecules of
hydrocarbons in the field of 3,3 - 3,4 microns wavelengths. For measurement of oxygen and toxic gases
concentration the device contains sensors which utilise the measurement principle of the
electrochemical method.
The device is also has a barometric pressure and temperature sensor to compensate for external
factors affecting the accuracy of measuring the concentration of gases, sensor data is not displayed.
For electrical power; a non-rechargeable chemical current source is used which is calculated
(depending on the modification) for 2 years of continuous operation.
