Proper cleaning and maintenance of portable particle analyzers are essential to ensure accurate measurements, prolong instrument lifespan, and maintain compliance with industry standards

Due to their intricate design, these instruments require careful attention to contamination control, ambient conditions, and mechanical integrity

Begin each use by inspecting the exterior surfaces for visible dust or debris

Use a soft, lint-free cloth lightly dampened with distilled water or a mild, nonabrasive cleaner recommended by the manufacturer to wipe down the casing

Refrain from applying harsh chemicals—even if commonly used—unless formally endorsed, since they risk corrosion or delamination of sensitive surfaces

Pay special focus to the sampling entrance and exhaust vents—they are prime sites for particulate accumulation

Persistent particle deposits can narrow passages, alter flow dynamics, and lead to erroneous output values

Use a gentle brush designed for electronics or compressed air at low pressure to remove loose particles

Do not probe the ports with any rigid instrument—this risks irreversible harm to embedded detection elements

Following each session in dusty conditions, activate the purge function with filtered air or nitrogen if available

This helps clear residual particles from the internal chamber and reduces the risk of cross-contamination between samples

Internal optics, such as lenses and light sources, are vulnerable to smudges and deposits that affect measurement precision

These components should only be cleaned by trained personnel using manufacturer-recommended tools and solutions

Cleaning usually involves lint-free pads saturated with 90%+ isopropyl alcohol, applied in concentric circles starting from the center

Wait until no moisture remains—no matter how slight—to avoid electrical shorts or lens fogging

Calibration is not merely a periodic task—it is a core component of maintenance

Adhere strictly to the vendor’s calibration timeline, adjusted for operational intensity and ambient exposure

Use certified reference particles for calibration checks, and document all results for traceability

When readings become erratic, show systematic drift, or trigger alarms, halt operations and conduct a comprehensive diagnostic along with recalibration

Maintain a detailed service journal recording all cleaning sessions, calibrations, component swaps, and irregular behaviors

Battery health should also be monitored

Avoid letting the battery fully discharge before recharging, 粒子径測定 and store the device with a partial charge if it will not be used for extended periods

Exposure to extreme temperatures, both hot and cold, can reduce battery efficiency and damage internal electronics

Always store the analyzer in its protective case in a clean, dry, temperature-controlled environment

Humidity levels above 60 percent can promote condensation, leading to circuit corrosion

Swap out disposable components—filters, hoses, and gaskets—on the schedule provided by the vendor

Worn-out parts may seem functional but can leach particles or vapors into the sample stream

Maintain a stocked inventory of key consumables to ensure uninterrupted operations

When transporting the device, secure it with padding to prevent physical shock, and avoid placing heavy objects on top of the unit

Finally, ensure that all users are trained in proper handling and maintenance procedures

Clear, documented workflows minimize mistakes and align team performance with manufacturer expectations

Regularly review the user manual and any updated firmware or service bulletins from the manufacturer, as new best practices may emerge

Dedication to meticulous upkeep ensures your analyzer delivers trustworthy results for years to come
