SAFETY NOTE:
Connection should be made via a PCB mounting socket. Soldering to pins will void the sensor's warranty.
It is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments, and operation;
If the Gas Sensor is removed from application circuit, a jumper should be added on 'R' and 'S' pin.
As applications of use are outside our control, the information provided is given without legal responsibility. Customers should test under their own conditions, to ensure that the sensors are suitable for their own. The data is given for guidance only. It does not constitute a specification or an offer for sale.
