Humidity Threshold Monitoring System

Description and Purpose

Storing paper, grain, certain chemicals, and other material that is negatively effected by humidity can be a challenge for kitchen and food service facilities, laboratories, hospitals, schools, and other facilities. Critical humidity levels are also needed in computer server rooms.  

If the facility has a number of storage units, the system can monitor each one with its own identification. If the facility currently provides individual humidity sensing units, the system can unify them into a single, easier-to-use system, many times using the existing humidity monitoring equipment. This makes the collection of storage units easier to manage from a single keypad annunciator. The system can also monitor the storage room door using a door position sensor. It can even provide a panic alarm for the inside to allow trapped personnel to call for help.

Capabilities and configuration depends upon the control panel that you choose.

Solving Humidity Issues

Those who use dry storage as a critical service for preserving or processing material are challenged with keeping humidity levels within an acceptable range. The system can monitor the dry compartment or room and sense when the humidity is too high. When the compartment is out of tolerance, the system can provide indications locally and transmit the indication to the central station to begin a pre-determined policy.

Weather patterns, power failures and extended door propping cause the humidity to drift out of range. The system can provide an immediate notification so that users can take action. When notified, users will typically find a tripped fuse, a power failure, the door ajar, or that the storage unit is in need of repair. Correcting the causal issue quickly saves the value of the dry compartment’s contents.
