Equipment Overview
The UL Water Spray Test Chamber is specially designed to evaluate the enclosure protection performance of self-ballasted lamps, lamp adapters, and U.S. standard charging connectors under controlled water spray conditions. By simulating UL-specified spray scenarios, the chamber tests the ability of electrical components to resist water ingress, ensuring their safety and reliability in real-world environments.
Equipped with three UL-standard spray nozzles, pressure meters, control valves, and a robust water supply frame, the system allows precise regulation of water pressure and nozzle distance to the specimen. Ideal for R&D labs, quality control, and certification testing, this chamber helps manufacturers verify waterproof performance and improve product durability.
Key Features:
Complies with UL water spray test standards
Adjustable nozzle distance and water pressure for accurate testing
Suitable for self-ballasted lamps, lamp adapters, and US standard charging connectors
Real-time monitoring with reliable pressure control
Ensures product safety and enclosure water resistance
Technical Parameters
| Distance between the center Nozzle and the Device | Approximately 1.4m (55 inches) |
