UV radiation illuminance meterIt is a core tool for monitoring ultraviolet intensity, and its core component - ultraviolet sensors (such as photodiodes or photovoltaic cells) are extremely sensitive to dust, high temperature, chemical corrosion, and mechanical damage. Good daily maintenance can significantly extend the lifespan of equipment (from 1-2 years to 3-5 years) and ensure measurement accuracy. Here are 5 key habits to extend their lifespan.

Habit 1: Clean the sensor promptly before and after use

The sensor window (usually made of quartz glass or sapphire material) is prone to dust, oil stains, or UV curing residues (such as UV glue debris), which can block light and result in low measurement values. After each use, gently wipe the window with a clean, soft dust-free cloth (or lens paper) to remove surface dust; If contaminated with stubborn stains (such as grease or chemical glue), dip a small amount of anhydrous ethanol (or specialized sensor cleaner) and gently wipe in a circular motion (avoiding scratching the window with excessive force), and then dry with a dry cloth. It is strictly prohibited to use steel wire balls, hard brushes, or corrosive solvents (such as acetone) to prevent window damage or sensor coating damage.

Habit 2: Avoid storing in high temperatures and direct sunlight

The core components of the ultraviolet illuminance meter, such as sensors and circuit boards, are temperature sensitive (working temperature is usually 0-50 ℃, and high temperature can accelerate component aging). After use, do not leave the device in a high temperature environment (such as near a recently closed UV curing box, where the temperature may be>80 ℃). It should be stored in a cool and dry place (ideal temperature 10-30 ℃). At the same time, avoid prolonged exposure to strong light (such as direct sunlight or strong ultraviolet lamps), as even if the device is turned off, ultraviolet radiation may cause the sensor to experience "light fatigue" (sensitivity gradually decreases). It is recommended to cover with a dust-proof box (or original packaging bag) during storage to reduce environmental light interference.

Habit Three: Regular Calibration to Ensure Accurate Measurement Benchmarks

The sensor of the ultraviolet illuminance meter may experience sensitivity drift over time (light aging) or frequency of use (high-intensity light irradiation), resulting in an increase in deviation between the measured value and the actual value. Even if no obvious faults occur, professional calibration (returning to the factory or comparing with standard ultraviolet light sources) should be carried out every 6-12 months (3-6 months for high-frequency usage scenarios). Calibration can correct deviations caused by aging or contamination, ensuring that measurement results always meet standards (such as UV glue curing requirements with strength deviation<± 5%). Neglecting calibration can cause equipment to work with defects, and long-term accumulated errors may lead to process failures (such as incomplete curing) or safety risks (such as excessive phototherapy dosage).

Habit 4: Handle with care to prevent mechanical damage

The sensors (especially precision photodiodes) and display screens (such as LCD or OLED) of the illuminance meter are very fragile, and severe vibrations or drops may cause sensor displacement (poor contact), window breakage (dust intrusion), or circuit breakage. When using, avoid throwing the device randomly on the desktop or toolbox. When carrying it, put it in a special shock-absorbing bag (or original portable case) to prevent collision with other hard objects. When installing the probe, handle it gently and avoid forcefully twisting or squeezing it, ensuring a stable connection without applying force.

Habit 5: Reasonable maintenance of batteries and circuits

If the illuminance meter uses rechargeable batteries (such as lithium batteries), the battery level should be kept at 40% -60% when not in use for a long time (to avoid battery bulging or failure caused by full or low battery storage), and charged every 3-6 months; If using dry batteries, they should be removed when not in use for a long time to prevent leakage and corrosion of the circuit. In daily use, avoid prolonged use in low temperature environments (<0 ℃) (battery performance may decrease, leading to sudden device shutdown), and regularly check the battery compartment contacts (clean with alcohol swabs to prevent oxidation and poor contact).

These 5 key habits (cleaning sensors, avoiding high temperatures and strong light, regular calibration, handling with care, and maintaining batteries) may seem simple, but they actually prolongUV radiation illuminance meterThe 'core secret' of lifespan. Through daily careful care, not only can the equipment failure rate be reduced, but also the accuracy and reliability of each measurement can be guaranteed, providing lasting support for the safety and efficiency of UV related processes.
