Digital function
​The Dräger VarioGard 3000 EC is connected with the controller via the digital VarioGard bus. This is how it is supplied with electricity and how it transmits its measuring results. You can easily control the entire VarioGard system via the VarioGard bus.

High reliability
​The VarioGard 3000 EC is equipped with an electrochemical DrägerSensor. This sensor measures the concentration of toxic gases in the ambient air. The measured values are transmitted digitally to the controller and displayed there. An alarm is triggered if the gas concentration exceeds one or more of the limit values configured.

Easy operation
​The operation is extremely easy. You can make all configurations comfortably from the controller using VarioGard software. You can configure and monitor four current limit values and four averages over time for each transmitter. The alarms are optically and acoustically displayed on the transmitter and transmitted to the controller. A three-colour LED indicates the operating status of the transmitter. The calibration is controlled using a magnetic wand via contact points.

Individually configurable
​The VarioGard 3000 EC is adaptable to your needs. This means that you have different sensors available depending upon the desired use:

CO, NO2 and NO for garages, O2 for oxygen supplies and NH3 for cooling facilities, for example.

In addition, you can place the cable inlets on all four sides of the transmitter. The transmitter can be mounted vertically as well as horizontally.
