WatchGas Replacement SO2 Sensor SST-SPARE-S CONFINED SPACE KITS That physiology has one operational

That physiology has one operational implication for SO2 monitoring: smell is NOT a reliable early-warning backup when the monitor drifts

Non-absorbing

For replacement foam inserts (in case of contamination

4-Gas Mix 34 Liter Calibration Gas (optional)

Because the setpoints are factory-set

WatchGas Replacement SO2 Sensor SST-SPARE-S CONFINED SPACE KITS That physiology has one operationalWhen your SO2 sensor drifts, you don't replace the whole monitor. You swap the sensor cell. That's the operational advantage of the serviceable WatchGas SST1 line. Traditional single gas monitors are single use when the sensor reaches end of life or a bump test reveals unrecoverable drift, the whole unit gets discarded. The SST1 platform is designed to be maintained: this WatchGas Replacement SO2 Sensor drops into the WatchGas SST1 S Serviceable SO2
