  • Data Logging Capability


You need to protect the equipment in your data center, computer room, or equipment room from the damaging effects of high temperature and high humidity. 

The best way to protect sensitive electronics is to constantly monitor the temperature and/or humidity in your data center, computer room, or server room and be notified immediately about an air conditioning system failure. 

TH Guard will give you immediate notification with a telephone alert call or an alert page. 

The early warning you receive will allow you to take corrective action before the servers melt down, bringing the enterprise to a halt.

The TH Guard will call up to four phone numbers or pagers to notify key personnel of a problem with any computer room, server room, or equipment room.  Call anytime and hear the temperature and humidity of any data center, computer room, server room, or equipment room.

For additional protection, water sensors can be connected to the TH Guard  to monitor for water leaks and warn you about damage from leaking air conditioners or pipes.

The TH Guard can be used as a simple single room temperature alarm, a multiple room temperature alarm, a simple humidity alarm, a multiple room humidity alarm, or any combination of sensors to fulfill your requirements for an environment alarm.

Advanced VM500-8-DCP-E model, in addition to the above features, you can set up a distributed data logging, monitoring and alarming system.

You have multiple sensors point and you are responsible for collecting and reporting temperature-humidity logs and then submitting them to various agencies.  The VM500-8-DCP-E makes this a simple task.  From your desk you can automatically collect and report temperature-humidity data from down the hall as well as all over the world.  The data can be graphed as well as exported to an Excel spread sheet.  Comes complete with software and an Ethernet cable.
