SenSmart 4000 Series Fixed Gas Detector - LIST OF DETECTABLE GASES
SenSmart 4000 Series Fixed Gas Detector - LIST OF DETECTABLE GASES
by RC Systems
- The SenSmart 4000 Series accepts only one of the four sensor technology types RC Systems manufactures: Electro-Chemical (EC).
- The table below lists the gases detected, with the sensor characteristics for each. If some of the gas types appear multiple times, look closely. The sensor specification differs in some way, such as the min/max span, or the sensor response time.
- When configuring your 4000 Series Gas Detector with SensorPros online you will be able to choose which sensor type you want, based on your application. The table below is only a partial list of the gases detected. If a gas is not listed, please call us and we will help you find a solution.
