Overview
The OK-SH-60 Stainless Steel Touchscreen Salt Spray Test Chamber is an engineered environmental test system designed to evaluate the corrosion resistance of metallic materials, coatings, and finished components under accelerated saline atmospheric conditions. It operates on the principle of continuous or cyclic salt fog exposure—generating a controlled, atomized sodium chloride (NaCl) aerosol within a thermally stabilized chamber—per ASTM B117 (Neutral Salt Spray), ISO 9227 (NSS/ACSS/CASS), and JIS Z2371 standards. The chamber’s fully welded 304 stainless steel construction ensures long-term structural integrity and chemical resistance against aggressive chloride-laden environments. Its integrated 7-inch capacitive touchscreen HMI provides intuitive real-time monitoring and control of critical parameters including chamber temperature, saturation tank temperature, spray duration, and operational status—all without requiring external PCs or proprietary software.
Key Features
- Corrosion-resistant 304 stainless steel interior and exterior housing with seamless welding and electropolished finish for enhanced durability and cleanability.
- Intelligent touchscreen interface with multilingual support (English, German, French, Spanish), password-protected parameter settings, and event logging capability.
- Dual-mode salt spray generation: precision-controlled pneumatic atomization for NSS (5% NaCl, pH 6.5–7.2) and ACSS (acidified copper-accelerated salt spray); optional CASS mode (0.26 g/L CuCl₂ + 5% NaCl, pH 3.1–3.3) with dedicated thermal management.
- Independent dual-zone temperature control: laboratory chamber (±1 °C accuracy) and saturated air reservoir (±1 °C accuracy), both regulated via PID controllers with platinum RTD sensors.
- Two-stage air pressure regulation system (1 kg/cm² nominal) ensuring stable, pulse-free nozzle operation and uniform fog distribution across the test volume.
- Comprehensive safety architecture: automatic power cutoff upon low deionized water level in the reservoir; thermal cutout at ≥3°C above setpoint; real-time brine solution level monitoring with LED warning indicators.
Sample Compatibility & Compliance
The OK-SH-60 accommodates standard test specimens up to 600 mm in height and supports rack-mounted, hanging, or flat-placed configurations per ISO 7384 and ASTM G85 Annex A5. It complies with regulatory requirements for quality assurance documentation under ISO/IEC 17025-accredited laboratories and supports GLP/GMP traceability when paired with external data acquisition systems. While the unit itself does not include built-in 21 CFR Part 11 compliance features (e.g., electronic signatures, audit trails), its event log export function (CSV via USB) enables integration into validated LIMS or ELN platforms for full data integrity governance.
Software & Data Management
No embedded PC or proprietary software is required—the OK-SH-60 functions as a standalone instrument with local HMI-based configuration and runtime supervision. All operational events—including start/stop timestamps, temperature deviations, safety interlock triggers, and manual parameter changes—are timestamped and stored internally for up to 30 days. Logs are exportable via USB flash drive in comma-separated values (CSV) format for post-test analysis in Excel, MATLAB, or statistical process control (SPC) tools. Optional RS-485 Modbus RTU interface enables remote monitoring and integration into facility-wide SCADA or MES systems.
Applications
This chamber serves R&D, QC, and certification labs across automotive (ASTM D1654 for painted panels), aerospace (AMS 2700 for cadmium-plated fasteners), electronics (IPC-J-STD-006 for solderability), and medical device (ISO 10993-15 for metallic implant coatings) sectors. Typical use cases include comparative evaluation of electroplated zinc-nickel vs. trivalent chromium passivation; validation of powder-coated aluminum housings per SAE J2334; and accelerated life testing of marine-grade stainless steels (e.g., UNS S32205) exposed to synthetic seawater mist.
FAQ
Is an air compressor included with the OK-SH-60?
No—the unit requires an externally supplied clean, oil-free compressed air source delivering 1 kg/cm² at the inlet port. Users must provide filtration (≤5 µm) and drying (dew point ≤10 °C) per ISO 8573-1 Class 4.
What type of water must be used for the brine solution and humidification?
Deionized water with resistivity ≥500 kΩ·cm is mandatory for both the salt solution preparation and saturation tank fill to prevent nozzle clogging and electrical conductivity drift.
Can the OK-SH-60 perform cyclic corrosion testing (CCT)?
Not natively—the OK-SH-60 is configured for steady-state NSS, ACSS, and CASS protocols only. Cyclic testing (e.g., ISO 11997, VDA 621-415) requires additional humidity, drying, and condensation modules not present in this base model.
How often should the nozzles and level sensors be cleaned or calibrated?
Nozzles require ultrasonic cleaning every 100 operational hours; level sensors should be inspected and wiped weekly. Temperature sensors are factory-calibrated and do not require user recalibration under normal operating conditions.
Does the unit meet CE or UKCA marking requirements?
Yes—the OK-SH-60 conforms to the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU, and carries CE marking. UKCA marking is available upon request with technical file submission to a UK-approved body.
