Features
1. Provide comprehensive and detailed real-time monitoring and curve recording for important test parameters such as irradiance, temperature and time (controller with recorder function), and generate reports and curve printing through computer.
2. Irradiation/condensation/water spray test can be conducted separately, or any combination of irradiation/condensation/water spray test can be programmed.
3. The independently developed industrial level 7-inch true color touch screen control system is adopted, with good stability, monitoring, operability and maintainability.
4. The service life of the imported ultraviolet lamp with expensive materials (the lamp is a consumable, and the service life is about 1600 hours) is provided to facilitate the user to confirm the replacement time of the lamp and save the use cost.
5. The automatic water supply and drainage design is adopted, and the high-power pump with high cost is used to ensure the flow rate and uniformity of water spray.
6. The installation and wiring of the electrical part of the equipment shall comply with the international electrical standards.

Chamber

Inner box material	The inner plate is made of high quality SUS304 stainless steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot workability are good, and there is no heat treatment hardening phenomenon (non-magnetic, use temperature - 196 ºC~800 ºC).
Outer box material	The box body is made of full numerical control, with advanced technology, smooth lines, and beautiful appearance. The external material can be made of high-quality SUS304 stainless steel or fine powder baking paint.
Equipment sample area	Dimension of standard test piece: 75mm * 140mm, 48 pieces, 75mm * 280mm, 24 pieces. (Non standard size can be customized) Schematic diagram of sample suspension at the illumination part of sample rack front

Control system

Controller	Self developed 7-inch super large touch intelligent controller: it has fixed value and program options.
Operation mode	Manual and programmed control
Input method	Touch screen
Setting method Program Editing	Constant value operation function: the user can use this function to realize continuous ultraviolet test function. In the customized operation screen, the user can manually control the opening and closing of each function. It can realize temperature adjustment and has the function of automatic temperature calculation.
	Program test run function: On the program control screen, the user can automatically run the equipment according to the edited program. When the program is running, the device has the function of keeping skip segments. And it can intuitively observe the total running time of the program, the running time of the program segment, the program number and other basic information. At the same time, the operation status of each system will be displayed on the screen intuitively.
Blackboard temperature monitoring	120 groups of programs can be programmed, and each group of programs can be programmed with a maximum of 100 segments, and cyclic operation can be set;
Communication interface	The standard Pt-100 blackboard temperature sensor is used to precisely control the sample surface temperature during the test process.
Ancillary functions	(RS232/RS485, maximum communication distance 1.2km [optical fiber up to 30km])
Controller	Fault alarm and cause, processing prompt function, power failure protection function, timing function (automatic start and automatic stop), self diagnosis function.

Operation & storage conditions

Installation place	The ground is flat and well ventilated, and there is no strong vibration around the equipment No strong electromagnetic field around the equipment No flammable, explosive, corrosive substances and dust around the equipment Proper use and maintenance space shall be reserved around the equipment.
Working conditions	Temperature: 5 ºC~ 28 ºC Relative humidity: ≤ 85% Air pressure: 86kPa~106kPa
Power supply	AC220 V, two wire+protective ground wire Installed power: 4.5 KW Allowable voltage fluctuation range: AC (220 ± 10%) V Allowable frequency fluctuation range: (50 ± 0.5) Hz The grounding resistance of protective ground wire is less than 4 Ω Users are required to configure air or power switch with corresponding capacity for the equipment at the installation site, and the switch must be used independently for the equipment
Storage environment	When the equipment is not working, the ambient temperature shall be kept within 0 ºC~+45 ºC. When the ambient temperature is lower than 0 ºC, the water in the equipment shall be drained to prevent the water in the pipeline from freezing and damaging the pipeline.
Others	Open the door of the test box during the test. Long time exposure to the open lamp will cause UV damage to eyes and skin. Please open the door as little as possible when starting the test.
