Product Details
ZN-S Water UV Light Test Chamber JG/T475-2015
Product use: Suitable for UV testing of sealants. The UV aging chamber uses UV lamps to simulate the effect of UV irradiation on products in water, and the tested material is placed under certain conditions of light for testing. It takes several days or weeks to reproduce the aging that occurred outdoors for months or years.
Reference standards: This product is designed and manufactured strictly in accordance with technical parameters such as JC/T883-2001 "Building sealants for stone materials", JC/T884-2001 "Building sealants for color coated steel plates", JG/T475-2015 "Silicone structural sealants for buildings", GB/T14683-2003 "Silicone building sealants", GB/T13477-2002 "Test methods for building sealing materials", JC/T485-2007 "Elastic sealants for building windows", JC/T882-2001 "Sealing sealants for curtain wall glass joints", etc,

2、 Light source
1. Users of the UV aging chamber can set the irradiation time themselves; Test time with power-off hold function, automatically resumes operation after power is restored. The equipment uses UV300W ultraviolet lamps as the light source, and conducts accelerated weather resistance tests on materials by simulating the UV radiation conditions in natural sunlight to obtain the results of material weather resistance. The effective service life of the lamp tube can be around 500 hours.
2. Accumulated/timed control of lamp irradiation time with power-off memory function (maintains original operating time and continues to operate when powered on again after power-off)
3、 Related configurations
1. One 300W ultraviolet lamp tube
2. One stainless steel sample holder
3. Inner box material: mirror stainless steel plate
4. Outer box material: steel plate with spray coating on the outer surface
5. 7.0-inch large touchscreen controller with automatic dimming capability
6. One set of installation type irradiation instrument（300～400nm）
After sales service: one-year warranty, lifetime maintenance, regular follow-up, listening to customer suggestions, establishing customer service files;
We promise to provide * and usage guidance services. For customers, we will respond within 1 hour. If technical service personnel need to be sent to the site for resolution, we promise to send personnel within 24 hours (except for special circumstances such as statutory holidays)
