DURPARK CO and NO2 detectors communicate using a proprietary protocol through three wires with the DURPARK control panel, allowing them to be addressed (1-16).
They are specially designed for use in car parks, with a new type of electrochemical sensor with low cost and great performance that allows a useful lifetime of up to 5 (CO) and 3 years (NO2) with almost no maintenance.
The CO model offers a range of 0-300ppm and a resolution of -+1ppm, and the NO2 model a range of 0-20ppm and a resolution of -+0.5ppm.
In the detector, calibration and maintenance tasks have been simplified. Algorithms have been created for gain and zero automatic calibration through the use of software, as well as an algorithm and a special hardware that allows verifying CO sensor sensibility without the need to apply gas.
For the CO detector, the composition of its electrolyte is respectful with the environment. Its structural shape cancels the risk of the electrolyte leaking. It does not use up active materials in its electrodes during operation, has a lower sensitivity to interfering gases, long life and good stability and precision.
A version is available with RS485 communication format and 4 wires that is compatible with the DURGAS control panel.
