WatchGas SST4-MINI & SST4-PUMP CAT LEL Sensor SST-SPARE-X2 Docking Station Using a 3rd gen photoionizationWhen your LEL sensor drifts, you don't replace the whole monitor. You swap the sensor cell. That's the operational advantage of the serviceable WatchGas SST4 line. This WatchGas Replacement CAT LEL Sensor drops into the WatchGas SST4 MINI Diffusion 4 Gas Detector and the WatchGas SST4 PUMP 4 Gas Detector when either is configured with a CAT (catalytic bead) LEL sensor. An LEL sensor is the fire channel of a 4 gas monitor. It doesn't measure toxicity
