Product Overview

Core Product Competitive Advantages

1. Multiple‑Option UV‑Fluorescent Lamp‑Configurations

   Supports interchangeable lamp‑types for distinct test objectives: UVA‑340 accurately reproduces solar near‑UV spectrum for real‑world outdoor‑exposure simulation; UVB‑313 delivers high‑intensity short‑wave ultraviolet for fast‑track quality‑screening; UVA‑351 is dedicated for indoor‑window‑filtered light‑ageing assessment. Lamp centre‑to‑centre spacing is fixed at 150 mm for consistent irradiation distribution.

2. Dual Moisture‑Simulation Modes: Condensation & Programmable Water‑Spray

   Condensation mode heats bottom water reservoir to generate water‑vapour; specimen‑surface temperature‑differential creates continuous liquid‑condensation, which faithfully simulates long‑term outdoor dew‑wetting conditions. The independent water‑spray subsystem drives multi‑nozzle spray cycles to achieve thermal‑shock and rain‑erosion simulation, configurable for spray‑duration and rest‑interval parameters.

3. Adjustable‑Height Specimen‑Rack & Full‑Stainless‑Steel Inner Compartment

   Lift‑modifiable sample shelf allows fine‑tuning of lamp‑to‑sample distance, catering for specimens of varying thickness. Both inner cavity and door liner adopt corrosion‑resistant stainless‑steel, resisting long‑term attack from hot‑steam and spray‑water. Compact overall footprint adapts to standard laboratory benchtop placement.

4. Flexible Programmable Cycle‑Logic & Power‑Failure Memory‑Retention

   Users build combined test‑profiles consisting of UV‑irradiation, dark‑condensation and water‑spray segments. Timer supports maximum 9999‑hour cumulative runtime, with power‑off memory function; testing resumes automatically once mains‑power recovers. KR‑308B touch‑screen edition enables visual multi‑segment recipe editing.

5. Precise Closed‑Loop Temperature‑Regulation & Complete Safety‑Protection

   Stable temperature‑control covers ambient up to 60 ℃. Elevated‑temperature settings accelerate ageing‑degradation while maintaining test‑repeatability. Built‑in protective interlock mechanisms mitigate risks from over‑temperature and abnormal operating‑states.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation
   Place cabinet on level lab‑bench surface and stabilise unit. Connect appropriate power‑supply; fill water‑reservoir with purified water for condensation and spray functions. Install selected UV lamp variant. Mount test‑specimens onto adjustable‑height sample rack, ensure samples are evenly spaced without overlapping shielding. Close and lock chamber door. Configure test‑program: temperature, runtime, illumination‑period, condensation‑duration and spray‑cycle parameters via physical‑buttons (KR‑308A) or touch‑screen (KR‑308B).
2. Initiate Accelerated UV‑Ageing Sequence
   Start test‑run. Equipment executes programmed sequence: UV‑irradiation phase, high‑humidity condensation phase and/or intermittent water‑spray phase. System maintains target chamber‑temperature throughout experiment.
3. Intermediate Observation
   Pause program periodically for visual inspection of specimen changes (discolouration, cracking, gloss‑variation). Avoid opening cabinet door during long‑time continuous‑operation whenever possible.
4. Test Completion & Specimen Evaluation
   When pre‑defined runtime expires, machine automatically terminates ageing‑process. Open cabinet door after internal space cools moderately. Retrieve specimens and perform visual assessment plus physical‑property measurement, record degradation symptoms for lab‑report documentation. Parallel‑sample testing is recommended for statistically‑trustworthy comparison results.
5. Post‑Test Tidying
   Remove all test‑pieces. Drain residual water from reservoir, wipe stainless‑steel inner cavity clean of water‑scale and debris. Shut‑off main‑power‑supply. Periodically inspect lamp ageing‑status, replace UV‑tubes upon reaching service‑life; clean water‑spray nozzles to prevent mineral‑deposit blockage.
