Notes:

Use only within specified conditions.
Do not disassemble or change any parts.
Do not touch sensor element.
Do not apply any direct current to the sensor.
Do not touch the film or the surface of the sensor.
In use and stock, freezing, dust, mist, oil, alcohol, corrosive gases or any other dirty/anomalous ambient may cause degradation of the sensors characteristics.
Protect the sensor film from flux/fume and high temperature during soldering.
Do not immerse sensor in water.
