✅ Introduction to Corrosion Testing and Its Importance

Corrosion is one of the most significant challenges faced by industries that rely on metal and coated components for structural, mechanical, or functional performance. From automotive parts and aerospace components to industrial machinery and marine infrastructure, corrosion can lead to material degradation, safety risks, and costly maintenance or replacement. To ensure durability, safety, and compliance with global standards, manufacturers need a reliable method to test how well their materials resist corrosion in aggressive environments.

This is where the Pakmo Salt Spray Chamber becomes essential. Developed by Pakmo Testing Instruments Pvt. Ltd., this advanced chamber offers unparalleled precision, automation, and reliability for conducting Neutral Salt Spray (NSS) tests in accordance with ASTM B117 and JIS Z 2371 standards. By simulating harsh environmental conditions in a controlled laboratory setup, the Pakmo Salt Spray Chamber helps manufacturers evaluate the effectiveness of coatings, paints, and corrosion-resistant treatments on metal surfaces.

⚙️ Designed for Precision and Performance

The Pakmo Salt Spray Chamber is more than just a corrosion tester; it is a smart, user-centric solution designed with high-grade components, modern automation, and intelligent control features. With its advanced HMI-based touchscreen, inbuilt PID temperature control, and auto refilling saturator system, it eliminates guesswork and manual inconsistencies, ensuring repeatable and accurate results every time.

This instrument provides a full-featured platform for conducting prolonged salt spray tests to simulate years of exposure in just days or weeks. The chamber environment is precisely monitored and maintained, offering exceptional control over temperature, humidity, air pressure, and salt fog generation.

🔬 Applications Across Industries

The versatility of the Pakmo Salt Spray Chamber makes it indispensable across various industrial sectors:

🚗 Automotive Industry

🛠️ Manufacturing and General Engineering

• Evaluates components like nuts, bolts, screws, bearings, and fittings

• Helps in process quality control and ISO/ASTM standard compliance

🖥️ Advanced HMI-Based Touchscreen Interface

The Pakmo Salt Spray Chamber is equipped with a modern 7-inch HMI touchscreen (TFT LCD) that brings a new level of usability and control. The interface is intuitive and provides real-time visibility of testing parameters such as:

• Chamber temperature

• Saturator temperature

• Test duration

• Air purge time

• Alerts and system messages

The HMI makes it easy for users to set test conditions, monitor real-time progress, view runtime logs, and make adjustments without navigating complex menus. The user-friendly layout ensures that even non-technical personnel can operate the machine with ease.

🌡️ Precision Temperature and Environment Control

Accurate temperature control is a cornerstone of reliable corrosion testing. The Pakmo chamber includes an inbuilt PID temperature controller, which ensures precise temperature regulation throughout the test duration.

🔧 Key Temperature Features:

• Test Chamber Range: Ambient to 40ºC

• NSS Test Temp: 35ºC ± 2ºC

• Saturator Range: 45ºC to 47ºC

• Least Count: 0.1ºC for both chamber and saturator

• Repeatability: ±2ºC

The saturator automatically refills when needed, minimizing manual intervention and reducing the risk of test interruptions. A corrosion-resistant PT-100 sensor ensures long-term accuracy and performance.

🧠 Smart Features for Enhanced Performance

Pakmo has equipped this chamber with several advanced features that help streamline operation and increase reliability:

• Auto air purge after test completion for fog settling

• Preset timer to automate test cycles

• Air regulator for adjusting test pressure up to 1.2 Kg/cm²

• Humidity indication (optional) to provide ambient condition feedback

• Data recording and USB export for documentation and traceability

• Alarm system for low water levels, low air pressure, and temperature deviations

• Auto tuning and Advanced Hysteresis Setting for precise PID performance

• Pneumatic canopy operation in 250-liter model for user convenience

🔒 Construction and Durability

Constructed using high-strength fiberglass (FRP), the chamber body is corrosion-proof, leak-proof, and designed for high-impact resistance. This ensures it withstands years of salt exposure without degrading or requiring costly maintenance.

The chamber interior is ergonomically designed for easy sample placement, and the angled canopy design prevents condensation droplets from falling onto test samples, preserving the integrity of results.

🧪 Optional Accessories for Customization

Depending on user needs, the Pakmo Salt Spray Chamber can be upgraded with optional accessories to improve test accuracy or versatility:

• Online pH meter – for continuous monitoring of salt solution’s acidity

• Tabletop pH meter – for sample preparation and quality assurance

• Standalone humidity indicator and sensor – for extra environmental control

These optional features make the system adaptable for research labs, manufacturing facilities, and quality testing departments with specific regulatory requirements.
