Regular upkeep of portable particle analyzers is critical for reliable data, extended device life, and adherence to regulatory requirements
Portable particle analyzers are highly vulnerable to dirt, humidity, temperature shifts, and physical stress, demanding a disciplined maintenance protocol
Before operation, always examine the outer casing for signs of accumulated dust or foreign particles
Gently clean the exterior with a microfiber cloth moistened in distilled water or an approved non-scratch cleaning solution
Do not use acetone, ether, or ethanol-based products unless the manufacturer permits them, as they may damage casing materials or lens coatings
The intake and outlet channels demand frequent inspection due to their direct exposure to airborne particles
Persistent particle deposits can narrow passages, alter flow dynamics, and lead to erroneous output values
Clean these areas using an anti-static brush or controlled bursts of filtered air, never direct high-pressure streams
Do not probe the ports with any rigid instrument—this risks irreversible harm to embedded detection elements
After each use, especially in high-dust environments, perform a flush cycle using clean, particle-free air or an inert gas if the device supports it
It eliminates leftover particulates from the measurement zone, minimizing carryover between tests
The optical pathway—including lenses, mirrors, and emitters—is easily compromised by fingerprints, oil residues, or dust films
Only qualified staff armed with manufacturer-specified kits should handle internal optics to prevent irreversible damage
Use high-purity alcohol-soaked swabs in gentle, spiral motions, beginning at the core and moving radially outward
Wait until no moisture remains—no matter how slight—to avoid electrical shorts or lens fogging
Regular calibration isn’t optional; it is the cornerstone of measurement integrity
Tailor your calibration intervals based on how often the device is used and the severity of surrounding conditions
Use certified reference particles for calibration checks, and document all results for traceability
If the analyzer shows inconsistent readings, drift, or error alerts, perform a full diagnostic and recalibration before proceeding with further measurements
Keep a maintenance log that includes dates of cleaning, calibration, part replacements, and any observed anomalies
Battery condition is a critical factor in operational reliability
Never allow complete depletion; recharge when the battery drops below 20%, and store it at 40–60% charge during long dormancy
Heat above 40°C or cold below 0°C can degrade cell chemistry and impair circuit function
Never leave the device exposed—always return it to its designated case in a controlled, debris-free space
Excess moisture above 60% RH risks internal condensation that may corrode traces and connections
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 粒子形状測定 vapors into the sample stream
Always have replacements ready—for filters, seals, and tubing—to avoid costly delays
Protect against vibration and impact by immobilizing the unit with shock-absorbing materials and never load weight on its surface
Finally, ensure that all users are trained in proper handling and maintenance procedures
Standardized protocols reduce human error and ensure consistency across teams
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
