The 120L Salt Spray Test Chamber is a professional corrosion testing equipment designed to evaluate the corrosion resistance and durability of materials, coatings, surface treatments, and industrial components under accelerated salt spray environments.

By simulating the corrosive conditions found in marine and atmospheric environments, this salt spray corrosion test chamber generates a controlled salt fog atmosphere to test the corrosion performance of various products, including metal parts, electronic components, automotive accessories, electrical products, hardware, plastics, electroplated coatings, FPC flexible circuit boards, and painted surfaces.

The chamber is widely used in industries such as automotive manufacturing, electronics, aerospace, hardware production, surface coating, electroplating, and quality inspection laboratories.

The 120L salt spray test chamber supports multiple corrosion test methods, including Neutral Salt Spray (NSS), Acetic Acid Salt Spray (AASS), and Copper Accelerated Acetic Acid Salt Spray (CASS), providing reliable and accurate corrosion resistance evaluation according to international testing standards.

Key Features of 120L Salt Spray Test Chamber

1. Multiple Salt Spray Corrosion Test Modes

The 120L salt spray corrosion chamber supports different accelerated corrosion testing methods:

• NSS (Neutral Salt Spray Test)
  Used for general corrosion resistance testing of metals, coatings, and surface treatments.

• AASS (Acetic Acid Salt Spray Test)
  Suitable for testing decorative coatings and protective surface finishes with higher corrosion requirements.

• CASS (Copper Accelerated Acetic Acid Salt Spray Test)
  Designed for accelerated corrosion evaluation of electroplated coatings and high-performance protective layers.

This multifunctional design makes the chamber suitable for different industrial testing requirements.

2. Accurate Temperature and Humidity Control

The salt spray test chamber adopts a precise temperature control system to ensure stable testing conditions.

• Test chamber temperature: RT +5℃ to 50℃

• Saturation barrel temperature: RT +5℃ to 63℃

• Temperature uniformity: ±1℃

• Temperature fluctuation: ±0.5℃

The accurate control system helps maintain consistent salt fog distribution and improves test repeatability.

3. Uniform Salt Fog Generation System

The advanced spraying system produces fine and evenly distributed salt mist inside the chamber.

Technical parameters:

• Salt deposition rate: 1–2 ml/80cm²·h

• Spray pressure: 0.7–1.2 ±0.01 kgf/cm²

• Spray mode: Continuous spray and intermittent spray

The uniform salt spray environment ensures reliable corrosion testing results.

4. Automatic Chamber Cover Opening System

The 120L salt spray test chamber is equipped with an automatic cylinder-driven cover opening system, which improves operational convenience and reduces manual handling risks.

The transparent chamber cover allows users to observe test samples during operation while maintaining a sealed corrosion environment.
