WatchGas SST1 External Filter for Fine Particles
Description
Dust, fine particles, and airborne contaminants shorten sensor life and compromise reading accuracy — the external filter stops them before they reach the sensor.
The WatchGas SST1 External Filter for Fine Particles fits over the SST1 single-gas monitor's sensor port and blocks particulates before they can accumulate on the sensor element. In any environment with significant airborne dust, particulate, or aerosol — grain facilities, mining, concrete and demolition work, chemical powders, heavy manufacturing — an unfiltered sensor is exposed to material that degrades its response over time. The external filter is a consumable barrier that takes the wear instead of the sensor.
When to use an external filter:
- Dusty or particle-heavy environments: grain handling, mining, demolition, construction, foundries
- Environments with chemical powders or aerosols that could coat or foul the sensor
- Any operation where sensor drift or sluggish response has been observed and environmental contamination is a likely cause
- As a standard protective measure on any SST1 monitor deployed in industrial or outdoor conditions
When to replace: inspect filters visually at each bump test or calibration. Replace when the filter material is visibly loaded with particulate, when it restricts airflow, or on a set interval — frequency depends on environmental conditions. Having a 10-pack on hand means a blocked filter doesn't interrupt a calibration run or leave a sensor unprotected.

Frequently Asked Questions
What does the SST1 External Filter protect against?
The SST1 External Filter blocks fine particles, dust, and airborne particulates from reaching the SST1 monitor's sensor element. In environments with significant airborne contamination — grain handling, mining, demolition, concrete cutting, chemical powders, heavy manufacturing — particulate accumulation on the sensor degrades response accuracy and shortens sensor life. The filter acts as a consumable barrier, taking the particulate load so the sensor doesn't have to.
How often should I replace the external filter?
Inspect the filter visually at each bump test or calibration cycle. Replace when the filter material is visibly loaded with particulate, shows discoloration consistent with contamination, or restricts airflow through the sensor port. In heavy-dust environments, replacement may be needed weekly or daily. In lighter-duty applications, monthly replacement is typical. Having a 10-pack on hand prevents a blocked filter from interrupting a calibration run or leaving a sensor unprotected between inspections.
Which WatchGas monitors does the SST1 External Filter fit?
The SST1 External Filter (SST-XF-10 / SST-XF-100) is designed for the WatchGas SST1 and SST1/E single-gas monitor series. It is not compatible with the SST4 series (SST4-MICRO, SST4-MINI, SST4-PUMP) or SST5 monitors. If you're unsure whether a filter is available for your monitor model, call PK Safety at
800.829.9580.
Can I use an external filter during bump testing and calibration?
The external filter should be removed before connecting calibration gas — whether using the
SST1 calibration cap for a standalone calibration or docking the monitor in the
WatchGas SST-DOCK. The filter is a protective barrier for ambient-air monitoring; it must be clear of the sensor port for calibration gas to flow accurately. Refit the filter after calibration is complete and you've returned the monitor to service.
