Technical specifications
- Model: LY-ZW-UV
- Product: UV climate aging test chamber for accelerated UV exposure, condensation and spray cycles
Key features
- Inner box: SUS304 stainless steel plate
- Outer box: cold-rolled steel plate with electrostatic spray finish
- Box cover: A3 steel plate with spray coating
- Heating: high-speed titanium-alloy electric heating for fast, uniform temperature
- Light source: 8 ultraviolet fluorescent lamps, 40 W each (4 per side)
- Sample rack: stainless steel and aluminum-alloy mesh frame for easy loading
- Base: fixed foot pads for stable installation
Control system
- 7-inch color touch-screen programmable controller with direct temperature readout
- Operation modes: programmable (program) or fixed-value control
- Temperature sensor: PT100 high-precision probe
- Controller displays program curve and trend charts and can save historical operating curves
- Programmable segments: up to 100 STEP; supports program grouping
- Power control: manual or scheduled on/off; configurable power-off recovery during program operation
- Communication: standard RS-232 or RS-485; optional PC software for data exchange
- Lighting, condensation and spraying can be controlled independently or cyclically; independent and alternating cycle times configurable (up to thousands of hours)
- Operation and setting errors trigger warning signals
- Philips ballast and starter supplied to ensure reliable UV lamp ignition
Specifications
- Outer dimensions: 580 × 1280 × 1350 mm
- Inner dimensions: 450 × 1100 × 500 mm
- Temperature range: RT+10 °C to 70 °C (adjustable)
- Temperature fluctuation: ≤ ±0.5 °C (no-load, steady state)
- Temperature uniformity: ≤ ±2.0 ~ 3.0 °C (no-load, steady state)
- Time setting range: 0–9999 minutes (continuous) and 0–9999 hours
- Lamp spacing: tube-to-tube distance 50 mm; center distance 70 mm
- Lamp power: 40 W each, total 8 × 40 W
- UV wavelength: 315–400 nm (UVA-340 band)
- Supporting template size: 75 × 300 mm
- Irradiance range: 0.3–1.51 W/m² (automatic dimming)
- Installation power: ~3.5 kW, 220 V ±10%, 60 Hz ±1; protective grounding resistance ≤ 4 Ω
Heating system
- U-shaped titanium-alloy high-speed electric heating tube
- Independent heating circuit separate from testing and control circuits
- Microcomputer-calculated output for precise and efficient temperature control
Safety protection device
- Over-temperature protection: if internal temperature exceeds 93 °C ±10%, power to lamp and heater is cut and the chamber enters a balanced cooling state
- Low-water-level alarm in the reservoir to prevent dry heating of the heater
Light source
- Q-Lab UVA-340 series: 40 W rated UV fluorescent tubes, arranged left and right (one tube every 7 cm)
- Lamp options per test standard: UVA-340 or UVB-313 (user selectable)
- Emission spectrum of UVA-340 concentrated between 315 nm and 400 nm
Technical specifications
- Model: LY-ZW-UV
- Inner dimensions: 450 × 1100 × 500 mm
- Temperature range: RT+10 °C to 70 °C
- Temperature fluctuation/uniformity: ≤ ±0.5 °C / ≤ ±2.0–3.0 °C
- Timing range: 0–9999 minutes or 0–9999 hours
- Lamps: 8 × 40 W (UVA-340), wavelength 315–400 nm
- Irradiance: 0.3–1.51 W/m² (automatic dimming)
- Power supply: ~3.5 kW, 220 V ±10%, 60 Hz ±1
