Standard Salt Spray Test Chambers
SP series salt spray test chamber is constructed with imported PVC & PP anti-corrosion hard plastic, featuring acid-alkali resistance, anti-aging and leak-free structure. It supports three mainstream corrosion test standards: NSS neutral salt spray, ASS acetic acid salt spray and CASS copper accelerated salt spray. Taking model SP-HL-90 as standard, its internal dimension reaches 900×600×500 mm, with controllable spray volume ranging from 1.0 to 2.0 ml/80cm²/h, temperature fluctuation controlled within ±0.5℃. Equipped with dual-language LED LCD touch screen and USB data storage port, it realizes remote computer linkage monitoring and automatic water replenishment to guarantee uninterrupted testing. This equipment is compliant with DIN 50021, ASTM B117, ISO 9227 and other global test standards, widely applied for corrosion resistance inspection of automotive parts, surface coatings, electronic components, aerospace and chemical materials.
Product Details
SP-HL-90
The whole machine adopts P.V.C material, corrosion resistance, easy to clean, no leakage phenomenon.
Using button type intelligent temperature control instrument, multiple sets of PID automatic routing,
high control precision, instrument can also be equipped with LCD touch screen.
108 l, 270 l testing machine cover adopts acrylic transparent roof, more than 480 l model adopts hard P.V.C plastic board, cover automatically opened and closed by cylinder, enclose the window light, may at any time to monitor the spray state machine and working state of the sample.
Tower spray system and device have salt liquid filter, no crystallization nozzle, spray uniform distribution, settlement free adjustment.
Sample number was laid (150 * 70 mm), such as 48 pieces can be placed in a 15 degree Angle, such as 32 can be placed in 30 degrees.
After completion of the experiment, with automatic mist device, the sample (s) can be observed clearly.
Clearance or continuous spray optional, multiple protection system, the use of safe and reliable.

SP-AHL-90
machine adopts imported PVC&PP hard plastic, solid structure, acid and alkali endurable, high temperature corrosion, never aging. Suitable for neutral salt fog NSS, acetic acid test along, copper acetate CASS and other experimental requirements.
Use plastic precision nozzle and conical spray, mist evenly fast, nozzle long service life, no crystallization.
Using LED LCD touch screen, can connect with computer to realize remote monitoring and operation, can be arbitrary switching in both Chinese and English.
With USB interface, can insert U disk to download historical data (the alternative recorder.
Internal control, spray time without additional time relay.
Through the flow meter, high pressure valve to regulate brine flow and pressure of compressed air, to ensure uniform settlement of salt fog.
Use the manual water system, water shortage with the function of automatically added, ensure continuity of test.
