Best Practices for Accurate Airborne Particle Detection
Choose Proper Sampling Locations
- Near air intakes and production areas
- Entrance/exits to controlled environments.
Follow Routine Calibration and Maintenance
- Regularly calibrate as per the manufacturer's guidelines
- Clean the optical path and check filter integrity.
Keep a Log of Environmental Conditions
- Temperature and humidity levels can influence particle counts; record these during sampling.
How Do I Maintain and Calibrate My Particle Counter?
Maintaining and calibrating your particle counter is very important for its accuracy and long-term performance. Regular maintenance includes keeping the device clean, inspecting the sampling probes, and replacing the filters on time. After each use, the device should be stored in a clean and dust-free place.
The calibration process typically follows the manufacturer's guidelines, which may involve using certified calibration equipment or getting verification from a third-party lab—this should be done every 6 months or once a year. Accurate calibration ensures that the particle counter gives correct readings, which is crucial for cleanroom compliance and quality control.
Regular Maintenance Tips for Longevity
First of all, always store the device in a clean and dry environment, and after use, gently wipe it with a soft cloth to prevent dust or contamination buildup. Inspect the sampling inlets and sensors at least once a week and replace or clean them if necessary.
Regularly check the power cable and battery, and install firmware updates if provided by the manufacturer. Changing the filters on time is also very important—it protects the device from blockage and sensor damage.
Also, never miss the calibration schedule; certified calibration should be done every 6 months or according to the manufacturer’s guidelines. These simple steps not only extend your device’s lifespan but also ensure accurate results.
| Issue | Possible Cause | Solution |
|---|---|---|
| Device not turning ON | The battery is dead or loose power connection | Charge the battery, check the power cable |
| Inaccurate readings | Outdated calibration or a dirty sensor | Renew calibration, gently clean the sensor |
| Data not saving | Storage full or software issue | Delete old data, update firmware |
| The screen is frozen | Software glitch or overheating | Restart the device, and contact the manufacturer if it happens repeatedly |
| Zero count error repeating | Sensor blocked or contaminated air | Clean air filter and inlets, rerun the zero count test |
| WiFi/Bluetooth not connecting | Network settings issue or outdated firmware | Reset settings, update firmware |
| Device overheating | Ventilation problem or prolonged usage | Let the device rest after use, and keep it in a cool and dry place |
| Unexpected shutdowns | Battery fault or hardware issue | Replace the battery, and have a technician inspect the device |
