NOTES
1. Use only within specified conditions.
2. Don’t disassemble or change any parts.
3. Don’t touch sensor element.
4. Don't apply any direct current to the sensor.
5. Don't touch the film and the surface of the sensor.
6. In use and stock, freezing, dust, mist, oil, alcohol, corrosive gases or any other
dirty/anomalous ambient may cause degradation of the sensor's characteristics.
7. Protect the sensor film from flux/fume and high temperature during the soldering.
8. Don’t put sensor in water.
