Pakmo’s CASS Cum Salt Spray Chamber with HMI Touch Screen

In industries like automotive, aerospace, defense, coatings, and electronics, corrosion remains a persistent and costly challenge. Products exposed to environmental factors such as humidity, saltwater, and chemical pollutants often suffer from degradation, rusting, and reduced service life. To ensure long-lasting performance and surface integrity, manufacturers rely on advanced corrosion testing methods. One of the most comprehensive and powerful solutions available today is the Pakmo CASS cum Salt Spray Chamber with HMI Touch Screen—a dual-purpose corrosion testing system that offers both CASS (Copper-Accelerated Acetic Acid Salt Spray) and NSS (Neutral Salt Spray) testing capabilities in a single unit.

Designed for maximum precision, user convenience, and global testing compliance, this chamber combines innovative automation with rugged construction to deliver accurate and repeatable results for every corrosion resistance evaluation.

What Is CASS Cum Salt Spray Chamber Testing?

Before exploring the features of the chamber, it’s important to understand the two corrosion testing methods it supports:

• NSS (Neutral Salt Spray): This is the standard salt spray test where a 5% NaCl solution is sprayed onto test samples in a controlled environment. It is ideal for evaluating paints, coatings, electroplating, and general metal protection.

• CASS (Copper-Accelerated Acetic Acid Salt Spray): This is a more aggressive form of salt spray testing where the solution contains copper chloride and acetic acid. It is used for testing anodized aluminum, chrome plating, decorative coatings, and high-end metal finishes where accelerated corrosion results are needed.

Having both these test modes in a single chamber gives users flexibility and cost-efficiency in validating a wide range of materials and finishes.

Professional Grade Testing Chamber – Built for Modern Labs

The Pakmo CASS cum Salt Spray Chamber is manufactured with high-grade Fibre Reinforced Plastic (FRP) for enhanced durability and chemical resistance. FRP is ideal for corrosive environments, making it a long-lasting choice even under continuous use with acidic and copper-laced solutions.

Its chamber body, internal sample holders, and mist delivery system are designed to endure both NSS and CASS solutions without deterioration, ensuring consistent performance over time.

Intuitive HMI Touch Screen Control

Modern laboratories demand smart control systems. The chamber is equipped with a fully digital HMI touch screen, offering:

• Feather-touch operation

• Test parameter setup (temperature, timing, spray interval, pause mode)

• Real-time monitoring of temperature and test status

• On-screen error detection and alarm alerts

• Historical data logging and test report access

Whether for R&D or production-line testing, the HMI system simplifies testing procedures and reduces the need for highly skilled operators.

Precise Fog Generation System

At the core of the system is a high-performance fog generation unit, featuring:

• Air saturator with heating element for pre-conditioning the compressed air

• Auto-refill mechanism to maintain optimal humidity and mist flow

• Special atomizer nozzles that evenly disperse salt fog or CASS mist throughout the chamber

The result is uniform and consistent exposure of samples to corrosive conditions—ensuring accurate test results that are reproducible and comparable to international standards.

Dual Solution Compatibility

The chamber includes a solution reservoir tank with clear markings and drain valves for:

• Neutral Salt Solution (NaCl + distilled water – NSS)

• Copper-accelerated Salt Solution (NaCl + CuCl₂ + acetic acid – CASS)

Operators can switch between test types with ease, following appropriate chamber cleaning and reconfiguration steps. The anti-corrosive tank materials and pipelines prevent contamination between test cycles.

Sample Flexibility and Large Test Volume

Pakmo’s chamber allows users to test multiple samples of varying sizes simultaneously. The internal space is designed for:

• Hanging or racking different types of metal sheets, plated parts, painted components

• Testing parts such as fasteners, automobile badges, hardware fittings, and more

• Long-duration testing up to 1000 hours for extended lifecycle simulations

Test setups are supported with angled V-shaped holders, rods, and racks for optimal fog exposure.

International Test Standard Compliance

Pakmo’s CASS cum Salt Spray Chamber is engineered to comply with major corrosion testing standards, including:

• ASTM B117 – Standard Practice for Salt Spray (Fog) Testing

• ASTM G85 Annex A1 – CASS Testing

• ISO 9227 – Corrosion Tests in Artificial Atmospheres

• JIS Z 2371 – Salt Spray Test Standards

• IS 9844 & IS 101 – Indian standard for coating and paint resistance

This makes the chamber suitable for export validation, client testing certification, and product development benchmarking.

Automation & Safety Features

To improve test efficiency and safety, the chamber includes:

• Automatic overheat protection

• Float-controlled water refill system

• Digital buzzer and display alert system for low solution or errors

• Transparent hood to observe samples during operation

• Safety interlocks to prevent chamber opening during the test

These features reduce manual errors, ensure operator safety, and protect samples from test interruption.
