Nitrogen Dioxide (NO2) Sensor:
Prana Air NO2 sensors have been created with panache and precision for consumer and industrial grade safety monitoring. The sensor comes packed with the cutting edge technology of electrochemical detection of the highly-toxic NO2 gas. The ultra-thin, compact, and cost-effective package allows easy-inclusion into all kinds of NO2 monitoring and regulatory solutions. Our sensors, with their precision, have the potential to revolutionize the scenario of environmental and health based monitoring of air toxins. These robust sensors, due to high operational life, find diversified applications in residential, industrial, and commercial instruments.
The sensor’s ultra-thin package and small size enables it to get lodged in any kind of device or instrument. It is suitable for hand-held devices as well as real-time outdoor monitoring.
The highly accurate NO2 sensor comes with a long-lasting operational life of up to 10 years. Install it in your instrument once and forget all your sensor related worries.
The average response time of this NO2 sensor is 15 seconds making it robust and swift. Hence, it is the apt choice for real-time monitoring.
It requires low power input (0 mW at 0 mV bias) to function. Therefore, the overall energy consumption of the device decreases due to this energy-saving sensor.
Individual calibration service procures readings with the highest accuracy for every device the sensor is put in.
Our NO2 sensor is synchronous to the Restriction of Hazardous Substances Directive (RoHS) for electrical and electronic equipment.
Technology We Use
What technology is being used in the device
Prana Air NO2 sensors work on the principle of the electrochemical gas sensing technique. These sensors are amperometric fuel cells designed to quantify the concentration of a gaseous toxin.
There are three principal components in this type of sensor- a working (sensing) electrode, a counter electrode, and an ion conductor that acts as a bridge between the electrodes. The toxic gas, NO2 is detected on the working electrode and gets oxidized with water molecules. This oxidation results in the formation of electrons and protons as by-products.
The directional flow of electrons through the wire creates an electric current that is directly proportional to the concentration of gas. The gas sensor works by measuring this current flow between the two sensors.
