gaz sf6 Transmitter - Draeger

The infrared sensor measures sf6 gas in the ppm range so the transmitter can detect a leak in time. It also makes it easier for you to comply with occupational exposure limits. Connect the Sulfr hexafluoride transmitter via an analogue or digital interface with a Dräger control unit to a gas warning system. This warns you early on exceeding the preset alarm values.Get price
