Wetness Monitoring - Care of Probes

The Environmental Monitor EM1 addresses wetness monitoring in a more sophisticated way than most wetness monitoring products. The Sensatronics range of probes do not just alarm on wet or not wet conditions, rather there is a wetness scale from 1 to 100, representing different levels of ’wetness’. The scale is an arbitrary one and may vary slightly from one probe to another but it is none the less useful as a guide to the degree of wetness. Setting a level too high may result in false alarms if humidity is high, so typically a value of around 40 would be used to trigger an alert.

Care of Sensatronics EM1 Wetness Monitoring Probes

Sensatronics Environmental Monitor Wetness Probes are robust, but bear in mind that they are sensitive devices and should be handled with care. However there are some basic handling rules that you should adhere to ensure accurate readings and long life from the probe. Once wetted a probe can be dried and used again.

• Avoid excessive handling of the wetness probe. Salt or grease from fingers could cause it to report false readings, especially in humid conditions.
• Avoid twisting or kinking of the probe, it is designed to be laid on the floor or coiled very loosely.
• If a probe gets wet or dirty, or begins to give false alarms, wash it carefully in distilled water. Try to avoid touching it with your fingers as much as possible.
• Hang the probe up in a warm, dust free area until fully dry.

If you require continuous wetness detection then it is a wise precaution to have a spare probe on hand to substitute for the one that has been cleaned.

Conclusion

Wetness Monitoring is as important as temperature and humidity monitoring in Server Rooms and Data Centers, to ensure early warning of leakage for instance from Air Conditioning Systems and to protect mission-critical devices. The Environmental Monitor EM1 Wetness probes are mechanically fairly robust but you should try to avoid handling them too much. Wetness probes can be used many times if properly washed and dried, to ensure continued wetness detection you should keep one or more spare probes on hand.
