Salt Spray Test Chamber

Product Overview

The Salt Spray Test Chamber is a specialized environmental testing device designed to simulate corrosive salt-laden environments to evaluate the corrosion resistance of materials, coatings, and components. Widely used in industries such as automotive, aerospace, marine, electronics, and metal processing, this chamber accelerates corrosion testing to predict product lifespan, validate protective treatments (e.g., galvanization, powder coating), and ensure compliance with international corrosion standards.

Key Features

Standardized Corrosion Simulation:
- Compliant with ASTM B117 (Salt Spray Fog Testing), ISO 9227 (NSS, AASS, CASS), DIN 50021, and other global standards.
- Supports neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) tests.
Precise Environmental Control:
- Temperature range: 35–50°C (adjustable with ±0.5°C accuracy).
- Spray rate: 1.0–2.5 mL/80 cm²/hour (programmable for consistent fog distribution).
- Salt solution concentration: 4–6% NaCl (with automatic calibration).
High-Performance Components:
- Corrosion-resistant stainless steel chamber and accessories (SS316L grade).
- High-pressure diaphragm pumps and nozzles for uniform fog distribution.
User-Friendly Operation:
- Touchscreen HMI with preloaded test programs and customizable parameters (test duration, temperature, spray intensity).
- Real-time monitoring of temperature, humidity, and salt concentration.
Safety & Durability:
- Overload protection, door interlock, and emergency stop function.
- Compact design with easy-to-clean drainage and fog collection systems.
