Overview
The HAIDA HD-M007FN Saltwater Immersion Tester is an engineered environmental simulation system designed to evaluate material resistance to saline corrosion under controlled immersion conditions. It operates on the principle of static or quasi-static immersion exposure—where test specimens are fully submerged in a temperature-regulated sodium chloride (NaCl) solution for defined durations—to accelerate electrochemical degradation mechanisms typical of marine, coastal, or de-icing salt environments. This apparatus supports standardized corrosion assessment protocols aligned with ASTM B117 (salt spray), ISO 9223 (corrosion classification), and GB/T 10125 (artificial atmosphere corrosion tests), while offering extended immersion capability beyond traditional fog-based methods. Its robust stainless-steel chamber, precision temperature control (±0.5 °C), and corrosion-resistant fluid-handling components ensure long-term operational stability and measurement repeatability across industrial QC labs, R&D centers, and third-party certification facilities.
Key Features
- Stainless-steel immersion tank with integrated heating/cooling system for stable bath temperature control (typically 20–50 °C range, configurable per test standard)
- Adjustable immersion depth and specimen mounting fixtures accommodating flat panels, coated metals, fasteners, polymer composites, and coated textiles
- Digital PID controller with real-time temperature monitoring and data logging interface (RS485/Modbus optional)
- Corrosion-resistant circulation pump (optional) for dynamic immersion testing per ISO 16701 or ASTM G85 Annex A5
- Integrated safety interlocks including low-level liquid detection, overtemperature cutoff, and leak-proof sealing design
- Compliance-ready architecture supporting audit trails, user access levels, and calibration documentation per ISO/IEC 17025 requirements
Sample Compatibility & Compliance
The HD-M007FN accommodates specimens up to 300 mm × 300 mm × 100 mm (L×W×H), with customizable rack configurations for multi-sample parallel testing. Compatible materials include ferrous and non-ferrous metals (e.g., galvanized steel, aluminum alloys), organic coatings (epoxy, polyurethane), elastomers, laminated composites, and packaging substrates. Test protocols executed on this platform align with international standards including ASTM D1141 (synthetic seawater preparation), ISO 9227 (neutral salt spray), ISO 16701 (cyclic corrosion with immersion), GB/T 10125, and JIS Z 2371. The system’s design facilitates integration into GLP-compliant workflows, with traceable calibration records and documented maintenance logs required for regulatory submissions under FDA 21 CFR Part 11 or EU MDR Annex I conformity assessments.
Software & Data Management
The HD-M007FN supports standalone operation via front-panel controls or PC-based supervision using HAIDA’s proprietary LabLink™ software (v3.2+). LabLink enables scheduled test initiation, continuous temperature profiling, event-triggered alerts (e.g., bath level deviation >2 mm), and export of time-stamped CSV reports compliant with ISO/IEC 17025 clause 7.7. Audit trail functionality records all parameter changes, operator logins, and system errors with immutable timestamps—meeting ALCOA+ principles for data integrity. Optional Ethernet connectivity allows remote monitoring via secure HTTPS endpoints, while firmware updates follow IEC 62443-3-3 security guidelines to mitigate unauthorized access risks.

FAQ
What concentration of NaCl solution is recommended for standard testing?
Typical concentration is 3.5 wt% NaCl (simulating natural seawater), though concentrations from 1–5 wt% are configurable per ASTM D1141 or customer-defined specifications.
Can the HD-M007FN perform cyclic immersion-corrosion tests?
Yes—when paired with optional external drying chambers or programmable environmental controllers, it supports ISO 16701 and ASTM G85 Annex A5 cyclic protocols involving immersion, drying, and humidity phases.
Is calibration certification included with shipment?
Each unit ships with a factory calibration report traceable to NIM (National Institute of Metrology, China) standards; UKAS-accredited calibration services are available upon request.
How is bath temperature uniformity verified during validation?
Per ISO/IEC 17025, temperature uniformity is validated using ≥9-point mapping with NIST-traceable PT100 probes; HAIDA provides IQ/OQ documentation templates for GxP environments.
Does the system meet electromagnetic compatibility (EMC) requirements for laboratory use?
Yes—the HD-M007FN complies with EN 61326-1:2013 for EMC and EN 61010-1:2010 for electrical safety, certified by SGS and TÜV Rheinland.
