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

These devices are sensitive to contamination, environmental factors, and mechanical wear, so a consistent and thoughtful care routine must be followed

Before operation, always examine the outer casing for signs of accumulated dust or foreign particles

Wipe the casing using a non-shedding fabric dampened with manufacturer-approved cleaning agents, avoiding excessive moisture

Do not use acetone, ether, or ethanol-based products unless the manufacturer permits them, as they may damage casing materials or lens coatings

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

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, 粒子形状測定 minimizing carryover between tests

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

Typically, optical wipes moistened with isopropyl alcohol of at least 90 percent purity are used in a circular motion from the center outward

Ensure all cleaned surfaces are fully evaporated before reinstallation or startup

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

Validate performance using accredited particle standards and maintain a permanent log of all calibration events

If the analyzer shows inconsistent readings, drift, or error alerts, perform a full diagnostic and recalibration before proceeding with further measurements

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

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

Avoid leaving the device in vehicles, direct sunlight, or freezing environments—they accelerate battery aging and risk component failure

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

Maintain humidity below 60% to prevent moisture-induced short circuits and long-term oxidation

Even if they look fine, replace filters, tubing, and seals at recommended intervals—they degrade silently and become contamination vectors

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

Keep spare parts on hand to minimize downtime

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

Uniform procedures eliminate variability and foster reliable results among multiple operators

Stay current by revisiting the handbook and checking for firmware patches or technical advisories

By investing time and care into routine cleaning and maintenance, users can rely on their portable particle analyzers for consistent, high-quality data over many years of service
