Hãng: PureAire Monitoring Systems

The PureAire Universal Gas Detector is a compact gas monitor that’s ideal for protecting workers from toxic and corrosive gas exposures in the workplace. It consists of a generic transmitter/controller connected to a dedicated, renewable gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Universal Gas Detector can also be connected to any programmable logic controller or SCADA system.
The heart of the system is a smart renewable sensor cell that’s programmed with the specific gas and measurement range information. Simply plug the sensor into any Universal Gas Detector transmitter and it’s ready to go. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas calibrated in the maintenance shop away from the transmitter.
