KR‑308 Fluorescent UV Accelerated Weathering Chamber
RT-308 ISO 20340 QUV Simulate Environmental Solar UV Accelerated Aging Testing Chamber
UV QUV test machine, the UV lamp can simulate the effect of the sun, condensation and water spray system can simulate the effect of rain and dew. the temperature can be controlled at the process of testing. A typical test cycle is usually testing at UV radiation of high temperature and the 100% humidity at dark; Typically used in paint and coatings, automotive, plastic products, wood products, glue, etc.
Product Details：
Product Overview
The KR‑308 fluorescent UV accelerated weathering chamber is laboratory‑grade environmental reliability equipment built for accelerated light‑ageing assessment. It utilises dedicated fluorescent UV lamps to reproduce the short‑wave ultraviolet component of natural sunlight. Combined with programmable condensation humidity and water‑spray cycles, it recreates real‑world outdoor stresses of sunshine, dew and rainfall.
Within several days or weeks of accelerated exposure, it reproduces typical long‑term outdoor degradation phenomena: colour fading, gloss loss, chalking, surface cracking, blistering, embrittlement and mechanical‑strength drop. Multiple interchangeable lamp types (UVA‑340, UVB‑313, UVA‑351) satisfy varied test‑norm requirements. Widely deployed for coatings, plastics, adhesives, wood‑based materials, automotive components and printing‑packaging goods in QC labs, material‑R‑D departments and accredited third‑party testing organisations.
Core Product Competitive Advantages
- Multi‑option interchangeable fluorescent UV‑lamp system
Accommodates three mainstream lamp variants. UVA‑340 closely mimics ground‑level solar ultraviolet spectrum for authentic outdoor‑correlation testing. UVB‑313 delivers high‑intensity short‑wave UV for fast‑track accelerated screening. UVA‑351 simulates UV radiation passing through window glass, ideal for indoor‑exposure material evaluation. Eight working lamps plus four spare lamps are supplied as standard; single lamp service‑life exceeds 1600 hours.
- Dual‑mode moisture simulation: condensation plus water‑spray
Heated‑tank condensation mechanism generates 100 %RH humid environment to mimic natural dew formation, reproducing long‑time wetting conditions of outdoor articles. Optional multi‑nozzle water‑spray assembly delivers intermittent cold‑water shower cycles, simulating rain‑induced thermal‑shock and surface erosion effects. Two moisture‑modes can be freely combined within segmented test‑programs.
- Precision closed‑loop temperature & optional irradiance control
Working‑temperature ranges 50 ℃‑75 ℃, with stable temperature holding during UV‑illumination and condensation phases. Optional irradiance‑monitoring sensor performs real‑time light‑intensity feedback, compensating for lamp‑ageing drift and securing repeatable test‑results across different batches.
- Heavy‑duty anti‑corrosion cabinet construction
Whole working cabinet is fabricated from SUS304 stainless‑steel plate. Internal air‑circulation duct together with high‑performance axial‑flow fan optimises temperature uniformity inside test cavity. Auto water‑replenishment avoids heater dry‑burn risk; U‑shaped drain‑structure handles waste‑water discharge conveniently.
- User‑friendly operation & large‑capacity sample‑holding layout
Stainless‑steel / aluminium‑alloy sample holders accommodate up to 48‑50 pieces of standard 75 × 150 mm specimens. Double‑flip top cover enables easy sample‑loading and routine internal inspection. Mobile PU castors support convenient workshop relocation. Touch‑screen controller supports multi‑segment cyclic‑program editing for fully‑unattended test‑running.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Place unit on level well‑ventilated ground. Check lamp condition, water‑supply pipeline, drain‑system and safety‑alarm functions. Prepare distilled water for tank filling. Mount specimens onto sample‑holders; keep test‑surface parallel to UV‑lamp plane. Close double‑flip cabinet cover and power‑on main‑unit.
- Program Parameter Configuration
Access touch‑screen interface. Edit multi‑segment test‑profile: set UV‑exposure duration, condensation period, water‑spray timing and target temperature. Activate irradiance‑monitoring function if radiometer accessory is fitted. Confirm water‑auto‑replenishment system operates normally.
- Execute UV Accelerated‑Weathering Test
Start saved test‑program. Equipment automatically cycles UV‑irradiation, high‑humidity condensation and optional water‑spray phases. System keeps tracking running‑parameters; alarm triggers upon abnormal status. Machine auto‑stops once total preset runtime is completed.
- Specimen Retrieval & Performance Assessment
Wait for inner‑cavity temperature to drop close to ambient. Open top cover and remove test‑samples. Inspect for fading, gloss‑reduction, chalking, cracking, blistering and embrittlement. Record observations for QC‑reports. Multiple replicate‑specimen testing is suggested for statistically‑reliable evaluation.
- Post‑Test Tidying
Drain waste‑water, clean cavity interior and sample‑holders of material residues. Check lamp surface for dust contamination. Reset program‑parameters. Shut‑down power for long‑term idle storage. Periodically inspect lamp ageing status and water‑system filter elements.
