Overview
The LabCompanion SH1-60 Salt Spray Test Chamber is an ASTM B117-23 and ISO 9227-compliant environmental test system engineered for accelerated corrosion evaluation of metallic and coated substrates. It operates on the principle of continuous or cyclic salt fog exposure under precisely controlled temperature, humidity, and solution concentration conditions. The chamber utilizes a pressurized saturation vessel governed by Henry’s Law to generate stable, saturated air at ≥95% relative humidity—ensuring consistent fog nucleation and eliminating condensation-induced variability. This thermodynamic control architecture, combined with direct steam injection heating via titanium alloy heating elements, enables rapid thermal equilibration (<15 min from ambient to 35 °C) and exceptional spatial temperature uniformity (±1 °C across working volume). Designed for long-term operational integrity in aggressive chloride environments, the SH1-60 integrates material-level corrosion resistance—from its 5 mm imported PVC chamber walls and SUS304 sample fixtures to its seamless SUS201 pressure vessel—making it suitable for routine QC validation, R&D screening, and regulatory compliance testing in electroplating, automotive, aerospace, and marine component manufacturing.
Key Features
- Pressurized saturation chamber operating per Henry’s Law principles, delivering ≥95% RH without external humidification systems
- Digital DHC PID temperature controller with platinum RTD probe and SSR output, maintaining ±1 °C stability during ASTM B117 salt fog cycles
- Quartz glass spray nozzle rated for ≥4000 hours of uninterrupted operation without salt crystallization or flow deviation
- Integrated conical fog disperser ensuring uniform deposition density (per ISO 9227 collection rate verification: 1.0–2.0 mL/80 cm²/h)
- Five-key intuitive interface with dedicated hardware switches for Power, Operation, Spray, Timer, and De-mist functions—enabling full manual override and deterministic state control
- Real-time fault detection system with LED status indicators for heater failure, low water level, pressure loss, and sensor drift
- Internal fog collection cylinder (ASTM-compliant geometry) eliminates mechanical damage risk associated with external funnels
- Titanium tubular heating elements provide superior corrosion resistance and extended service life compared to conventional nickel-chromium alloys
- Mobile structural base with industrial-grade swivel casters (standard on SH1-120+; optional retrofit available for SH1-60)
Sample Compatibility & Compliance
The SH1-60 accommodates specimens up to 400 mm in depth, mounted at a fixed 30° inclination via V-shaped plastic-steel supports and SUS304 suspension rods—meeting ASTM B117 angular orientation requirements for standardized corrosion assessment. Its chamber interior is fully lined with 5 mm imported gray-white PVC, offering chemical inertness against 5% NaCl, CuCl₂-accelerated, or acidic salt solutions (e.g., pH 3.1–3.3 per ISO 9227 AASS). All wetted components—including the pressure vessel, piping, and nozzle assembly—are fabricated from corrosion-resistant alloys (SUS201, SUS304, quartz, titanium) to prevent metallic ion leaching that could compromise test validity. The system complies with key international standards including ASTM B117, ISO 9227, JIS Z2371, and GB/T 2423.17. Optional calibration documentation supports GLP/GMP audit readiness, and firmware logs are timestamped and non-erasable—facilitating 21 CFR Part 11-aligned data integrity when paired with LabCompanion’s optional data export module.
Software & Data Management
While the SH1-60 operates as a standalone hardware-controlled instrument, its embedded timer and temperature controller retain full event logging capability. All time-stamped operational parameters—including start/stop timestamps, setpoint deviations, fault codes, and accumulated spray duration—are stored in non-volatile memory with battery-backed retention (10-year minimum). For laboratories requiring electronic records, LabCompanion offers the optional RS-232/USB data logger interface (sold separately), enabling automated CSV export of real-time temperature, timer status, and alarm history to LIMS or ELN platforms. The system supports configurable audit trails compliant with FDA 21 CFR Part 11 Annex 11 requirements when deployed with validated software drivers and user access controls. No cloud connectivity or proprietary cloud services are embedded—ensuring full data sovereignty and alignment with ITAR and EU GDPR infrastructure policies.

FAQ
What standards does the SH1-60 comply with for salt spray testing?
The chamber meets ASTM B117-23, ISO 9227:2022, JIS Z2371, and GB/T 2423.17 for neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) test methods.
Can the SH1-60 perform cyclic corrosion testing (CCT)?
The base model supports only continuous salt fog operation. Cyclic functionality (e.g., dry/humidity/spray phases) requires integration with LabCompanion’s optional CCT-Link controller module and auxiliary humidity/temperature chambers.
Is the quartz spray nozzle replaceable, and what is its expected service life?
Yes—the nozzle is field-replaceable and certified for ≥4000 hours of uninterrupted operation under standard 5% NaCl solution at 35 °C, provided proper filtration and solution maintenance protocols are followed.
Does the system include calibration certificates traceable to NIST or other national metrology institutes?
Factory calibration reports (temperature, timer, fog collection rate) are included. NIST-traceable certification is available as a paid option with third-party accreditation (ISO/IEC 17025).
