・Evaluation of gas sensitivity should be made in clean air.
・Take care not to block the gas intake area as it may prevent gas entering the sensor.
・After the sensor is exposed to high concentration gas for long periods, the output signal may require
time to recover to normal operation.
・Do not blow organic solvents, paints, chemical agents, oils, or high concentration gases directly onto
sensors.
・Never put foreign material in the gas intake area as it may cause the electrolyte leakage
・Do not bend the pins.
・Do not apply more than 5 kgs/cm2 to the sensor housing.
・Do not expose the sensor to excess vibration or shock.
・Sensor can be soldered, but by manual soldering and the temperature of a soldering iron must be less
than 350o C be applied for less than 3-seconds. Excess heating may cause the deformation of the
housing and eventually leakage of electrolyte.
・Refrain from using reflow soldering or solder bath with PCB’s fitted with a sensor.
・If the sensor housing is damaged, do not use the sensor.
・Do not disassemble the sensor as this may cause electrolyte leakage.
・If the sensor is to be used in more irregular atmospheres, please contact us for assistance.
