Equipment summary:
This equipment is suitable for the test of rainproof and immersion sand for industrial electronic products such as auto parts and electronic appliances. The auto parts include outdoor lamps, lights, door locks, electrical, instrument, dust jacket, electronic Testing of the complete sealing stability of systems such as household appliances.
The rain tester is a combination type, which is controlled by IPX5 IPX6 rain test level combination. It saves the customer’s laboratory space and saves 6 cubic meters of water per hour. Control mode programmable control system, set by touch screen setting interface. Set the spray time and independent sample carousel control.

Core Product Competitive Advantages
- Corrosion‑resistant full stainless‑steel wet‑zone construction
Inner cavity, rotating sample turntable and complete water‑circuit components are manufactured from SUS304 stainless‑steel material. It delivers long‑term rust‑proof performance under continuous water‑spray and high‑humidity operating conditions. The fully‑sealed turntable drive motor prevents water intrusion into electrical parts.
- Programmable touch‑screen intelligent operation
Colour touch‑screen HMI enables quick parameter setup for spray duration, turntable rotation speed and test‑mode switching. IPX5 / IPX6 can be activated via one‑touch command. System executes auto‑stop once pre‑set test duration is completed, minimising manual‑operation errors for routine QC workflows.
- Precision‑regulated water‑jet performance
Equipped with rotor flowmeters for intuitive water‑flow adjustment. Standard‑compliant interchangeable nozzles deliver accurate flow‑rate matching for each IP‑level requirement. High‑performance multistage stainless‑steel water pump guarantees stable water‑pressure output throughout long‑duration testing cycles.
- Self‑contained water‑supply system with multi‑layer safety safeguards
Built‑in water reservoir features float‑valve automatic water‑replenishment and low‑water‑level alarm function to protect water‑pump against dry‑run damage. Comprehensive protection covers electric‑leakage, short‑circuit and overload fault conditions.
- Flexible sample‑holding layout & mobile‑friendly cabinet
Sample turntable supports stepless speed adjustment plus forward‑reverse rotation, avoiding cable‑twisting risk for energised‑specimen testing. Heavy‑duty casters with locking brakes allow convenient re‑positioning inside labs or production workshops. Large viewing window permits visual monitoring of test progress without opening the chamber door.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Position equipment on level workshop floor and lock casters. Inspect water‑tank water‑level condition, nozzle assembly and turntable running status. Secure test‑samples firmly onto rotating platform; route power‑supply cables properly if energised testing is needed. Close chamber main door tightly. Switch‑on main power supply.
- Parameter Configuration
Access touch‑screen control panel. Select target IP‑test grade, set required test‑running‑time and configure turntable rotating‑speed. Adjust flow‑meter to achieve standard‑specified water‑flow value.
- Execute Water‑Ingress Simulation Test
Trigger test‑start command. Equipment carries out continuous water‑spray procedure according to pre‑loaded profile. Turntable rotates steadily so all surfaces of specimen receive uniform water impact. Machine automatically terminates upon completion of preset timing.
- Post‑Test Sample Retrieval & Evaluation
After test sequence finishes, open cabinet door and remove specimens. Examine enclosure interiors and structural gaps for water‑ingress traces. Document water‑penetration status for quality‑inspection reports. Multiple replicate tests are recommended to acquire reliable assessment conclusions.
- Post‑Test Tidying
Drain residual water inside chamber cavity. Wipe stainless‑steel inner surfaces to remove water‑stains. Clean nozzle orifices to prevent mineral‑deposit clogging. Reset all program‑parameters. Cut‑off main power for long‑term idle storage. Periodically inspect water‑circuit seals and pump‑operating‑condition.
