Electro-chemical Sensor
Solid polymer electrochemical technology is a revolutionary innovation in the field of electrochemical detection.
In essence this technology is based on the principle of electrochemical catalytic reaction. As a general rule the sensors respond to the target gases and deliver a very small current signal that is usually proportional to the gas concentration.
Usually, electrochemical sensors are using either a liquid or a gel electrolyte which leads to a couple of challenges during the operation of the sensor.

Work in Hostile Environment
Industrial parts are available for gas monitoring in hostile environment, such as a continuous high ammonia environment such as a pigsty.
Gaseous NH3 can become acidic when coming in contact with moisture. This ECtox stainless steel probe can measure the continuously high ammonia concentration while keeping its long lifetime.
