In many fields of work, quick and reliable gas detection is a must. This is why we offer the Dräger VarioGard® stationary gas detector range. The Dräger VarioGard® 2300 IR monitors possible gas leaks of methane or LPG.
• The one to count on
• Simple set-up and handling
• Gas library and variable measuring ranges
• Standardised output signal
The Dräger VarioGard 2300 comes equipped with highly precise infrared optical sensors, which greatly reduce the possibility of false alarms so that it should only sound when real danger is evident. The IR sensors are also extremely robust and rarely need to be recalibrated.
Type
Transmitter for the measurement of concentrations of gases in the ambient air
Gases and measuring ranges
CH4 : 0 to 100 % LEL
LPG : 0 to 100 % LEL
