Handheld Gas Analyser Filters

Here are some key points about the filters used in handheld gas analysers:

1. Purpose:
   - Particulate Filtration: To prevent dust and particulate matter from entering the analyser, which could damage the sensor or interfere with readings.
   - Moisture Removal: To remove moisture from the gas sample, as humidity can affect sensor accuracy. This is where our excellent coalescing filters are used. 
   - Chemical Filtration: To eliminate or reduce the presence of interfering gases that could skew the results.
   
   
2. Types of Filters:
   - Particulate Filters: Our borosilicate glass microfibre filters are designed to trap dust and other solid particles.
   - Desiccant Filters: Headline Filters disposable inline filters contain materials like silica gel or molecular sieves that absorb moisture from the gas sample.
   - Chemical Filters: Often use activated charcoal or specific chemical absorbents to remove or neutralize interfering substances.
   
   
3. Replacement and Maintenance:
   - Filters need to be checked regularly and replaced according to the manufacturer's guidelines to ensure they function correctly and do not become clogged or saturated.
   - Proper maintenance extends the lifespan of the analyser and maintains accuracy.
   
   
4. Compatibility:
   - Filters must be compatible with the specific gases being measured and the operating environment of the analyser.
   - Some analysers come with customizable filter options to suit different applications.
   
   
5. Common Applications:
   - Industrial Safety: Monitoring toxic gases in factories.
   - Domestic & Commercial Boilers: Flue gas analysis including oil boilers.
   - Environmental Monitoring: Checking air quality and pollution levels.
   - Medical: Monitoring gases in healthcare settings.
   

When selecting or replacing filters for a handheld gas analyser, it's important to refer to the manufacturer’s recommendations to ensure optimal performance and safety.
