AWT/Mini UV Accelerated Weathering Tester – Tabletop Model
The AWT/Mini UV Accelerated Weathering Tester reproduces sunlight, rain, and dew to simulate the effect of sunlight using fluorescent ultraviolet lamps, and simulates rain and dew with condensing humidity — accelerating specimen ageing through alternating cycles of light, moisture, and controlled elevated temperatures.
For some applications, the water spray can simulate end-use environmental conditions better — effectively replicating heat shock or mechanical erosion caused by dramatic temperature changes or rain. The spray system can run for a few minutes and then shut down, cooling samples quickly to create heat shock conditions.
Built with corrosion-proof stainless steel construction, this compact tabletop model is a user-friendly automatic instrument that finds material damage in a short time — predicting the damage formed under natural conditions over long periods and judging quality differences between tested products and samples.

Water spray system simulates end-use environmental conditions, heat shock, and mechanical erosion — spray runs for programmable intervals then shuts down, rapidly cooling samples to create realistic thermal shock conditions
Corrosion-proof stainless steel construction with touch panel control — compact, durable tabletop design for convenient operation and maintenance in any laboratory setting
Accommodates 18 standard panels (150×70mm each) with fully programmable test, spray period, and spray timers — identifies material damage in a short time that predicts long-term natural weathering performance
Key Highlights
UV + Moisture Weathering Simulation
Reproduces sunlight (UVA 340nm or UVB 313nm), rain, and dew simultaneously using fluorescent UV lamps, condensing humidity, and a programmable water spray system for realistic accelerated weathering.
Precise Temp & Timer Control
Adjustable temperature from RT+5°C to 80°C with independent timing for test period (up to 9999h), spray period, and spray duration — fully programmable cycles via touch panel for any test protocol.
Compact 18-Panel Tabletop Design
Corrosion-proof stainless steel construction in a 1000×600×800mm footprint holds 18 standard panels (150×70mm each) — ideal for laboratories requiring powerful weathering testing in a compact space.
The AWT/Mini UV Accelerated Weathering Tester is used to simulate the damaging effects of outdoor weathering — including sunlight, rain, and dew — in a controlled laboratory environment. It accelerates specimen ageing through alternating cycles of UV light, moisture, and elevated temperature to predict long-term material durability in a fraction of the time.
The AWT/Mini supports two UV lamp options: UVA lamps at 340nm and UVB lamps at 313nm. UVA 340nm best replicates the solar spectrum near the UV/visible cutoff and is used for general outdoor durability testing. UVB 313nm provides more intense UV exposure and is used for applications requiring faster degradation results. Each configuration uses 3 lamps at 20W each.
The AWT/Mini can accommodate 18 standard size test panels simultaneously, with each panel measuring 150mm × 70mm. This capacity allows multiple specimens to be tested in a single run, making it efficient for comparative testing of different materials or formulations under identical exposure conditions.
The AWT/Mini working chamber temperature is adjustable from RT+5°C (5°C above room temperature) up to 80°C. This wide range covers most accelerated weathering test protocols and allows realistic simulation of elevated-temperature outdoor conditions such as those found in tropical or desert environments.
The AWT/Mini offers three independently programmable timers: the test period timer ranges from 1h to 9999h; the spray period timer ranges from 1min to 9999min; and the spray timer ranges from 1min to 99999min. This flexibility allows the machine to replicate a wide variety of real-world weathering exposure schedules from short-term to very long-duration tests.
The UV fluorescent lamps in the AWT/Mini have a rated life of 1,000 hours. The machine uses 3 lamps of 20W each (UVA 340nm or UVB 313nm). Lamp replacement is straightforward due to the convenient stainless steel construction and user-friendly design, minimizing downtime during maintenance.
The AWT/Mini Tabletop Weathering Tester measures 1000 × 600 × 800mm (L × W × H) and weighs 110 kg. It operates on 220V, 50Hz, 4A power supply with a total power consumption of 1.2 kW. Its compact tabletop footprint makes it suitable for standard laboratory benches while still offering full-featured 18-panel weathering capability.
Yes. The AWT/Mini is equipped with a water spray system that simulates rain and dew conditions. It can also simulate heat shock and mechanical erosion caused by rapid temperature changes. The spray system runs for a programmable period and then shuts down, rapidly cooling samples to create transitory heat shock conditions — making it suitable for applications that require both UV and moisture testing.
