Products Description
MSA 0-56950-40 Gas Sensor

Feature & Principle
It is an electrochemical oxygen sensor for MSA gas transmitter. It relies on electrochemical reaction principle to detect oxygen concentration in the air. Oxygen molecules pass through the permeable membrane and react inside the electrolytic cell, generating current signal proportional to oxygen content. The signal is sent to the detector host for calculation, alarm and data upload, with fast response speed and stable output.
