Salt Spray Corrosion Test Chambers

.

The SF series of salt spray corrosion test chambers by North American Envirosystems deliver high-reliability environmental testing built to withstand rigorous international standards (such as ASTM, ISO, MIL-STD, DIN, and automotive standards). Designed with a non-metallic, molded Fiber Reinforced Plastic (FRP) body, these chambers provide non-corrosive, long-life performance with advanced automation.

Construction & Core Hardware Features

Non-Metallic Structure: Molded Fiber Reinforced Plastic (FRP) body coated with PU-based paints for full corrosion protection.
Tapered Hood: Non-metallic hood prevents condensation drops from falling directly onto test specimens.
Water Seal Channel: Ensures fog does not escape into the laboratory environment.
Pneumatic Door Operation: Assisted hood movement for safe and easy access.
Atomizer Tower: Acrylic atomizer producing < 500 micron droplets for uniform fog delivery.
External Solution Tank: 50 L solution tank equipped with lid and filter for easy preparation and cleaning.
Levelling Casters: Heavy-duty anti-vibration casters for effortless mobility and levelling.
Isolated Electrical Panel: Fully isolated control housing to shield electronics from corrosive fog and moisture.

Control Platform & Automation

Interface: 5.7" or 7" TFT color touch screen with integrated PLC.
Programmer: Supports continuous 12-step test programming for complex cycle standards.
Connectivity: Ethernet and USB ports for real-time monitoring and downloading test data (graphical and tabular).
Security & Diagnostics: 3-tier user security (User, Admin, Factory) and automated preventive maintenance notifications.
Safety Alarms: Comprehensive monitoring for solution level, saturator water level, humidity tank, air pressure, and zone temperatures.
