Electrochemical Sensor Based Analysers for CO,NO,NO2, SO2, O2 and many more gases
SERIES 89 PORTABLE / FIXED POINT TOXIC GAS ANALYSERS THE INSTRUMENT - LOW COST DEPENDABLE & INDIGENOUS
TOXIC GAS ANALYSERS SERIES 89 accurately measure the concentration of a particular gas in parts per million (ppm). These analysers may be used as a DESK-TOP model or PANEL-MOUNTABLE. These toxic gas analysers use electrochemical sensors which have an enviable reputation for reliability, stability and rugged design having an electrical output linearly proportional to concentration level of the gas. Ambient air monitoring can be done continuously. Process gas may be monitored only under certain conditions and levels.

Available Model : SERIES 89
Applications
These instruments find application in Process Control, Quality control and Safety in work areas of Factories and Research institutions
