3 8 flexible gas line for sale, brand-new and used.

The QuadScan II has been developed with an abundance of built-in, flexible features that make it the ideal receiver to economically centralize display and alarming for up to four gas transmitters, fire detectors, or other 4-20 mA instruments. QuadScan II’s in-the-field “Channel Expansion” feature allows users to initially purchase only the channels they need. Unused channels can then be easily activated with the purchase of a passcode.
