[Notes]

?Use only within specified conditions.

?Sensor characteristics must be measured in clean air.

?Electrode pins must be correctly connected.

Wrong connection does not allow correct functions.

?Do not apply voltage directly to electrode pins.

?Do not bend pins.

?Do not put excess vibration or shocks.

?If sensor housing is damaged or scratched, do not use.

?Do not blow organic solvents, paints, chemical agents, oils, or high concentration gases

directly onto sensors.

?Do not solder to pins of sensor directly.

Use exclusive sockets.

?Do not use contact grease when sensor connected to the sockets.

?Do not disassemble or change any parts.

?If sensor is used under irregular atmosphere, contact us.
