Environment Monitor

Responsive image

The VP-TX-DCIM is a complete environment sensing / monitoring / alarm indicating transmitter designed exclusively for data centre applications. This device hosts multiple sensors for temperature, humidity, differential static pressure, carbon monoxide gas and water leaks.
The basic model has one internal temperature sensor, one internal humidity sensor, and up to four external (remote mounted) temperature sensors.

Each VP-TX-DCIM (Basic) Environment Monitor hub monitors:

Up to 6 VP-TX-DCIM Hubs can be connected to a VP-EC-DCIM Gateway and the “Enviro Cloud” web app for a total of 30 Temperature Points, 6 Humidity Points, 6 CO Gas Points, 6 Differential Static Pressure Points, and 6 Water Leak Detection Points.
