Q-FOG SSP & CCT Cyclic Corrosion Testers | Salt Spray Testers Malaysia
If you are searching for Salt Spray Testers in Malaysia, you likely need dependable corrosion data to qualify coatings, plated parts, fasteners, or assembled components. H. J. Unkel (M) Sdn. Bhd. supplies industrial Q-FOG salt spray and cyclic corrosion test chambers for Malaysian manufacturers and laboratories—supported by local technical guidance on standards, methods, and test setup.
What is a salt spray tester?
A salt spray tester (salt fog corrosion chamber) is a controlled test chamber that exposes specimens to a fine mist of salt solution at defined temperature and spray conditions. It accelerates corrosion to compare materials and coatings under repeatable lab conditions.
Why Malaysian manufacturers use salt spray & cyclic corrosion testing
Malaysia’s heat and humidity can accelerate real-world corrosion—especially for components used near coastal or outdoor environments. Salt spray and cyclic corrosion testing help engineering and QA teams validate protective systems before shipment or approval.
Automotive & components
Validate coatings and fasteners using cyclic methods that better reflect wet/dry exposure and underbody conditions.
Metal finishing & coatings
Compare plating, paint systems, and pretreatments for relative performance and supplier qualification.
Electronics & electrical
Screen housings, connectors, and assemblies where corrosion can cause failures, leakage currents, or cosmetic defects.
Salt spray vs cyclic corrosion: which should you specify?
Conventional salt spray (continuous fog) is widely used for comparative testing, while cyclic corrosion adds wet/dry and humidity phases to improve correlation to outdoor exposure—often preferred for automotive and advanced coating systems.
| Requirement | Conventional Salt Spray (NSS) | Cyclic Corrosion |
|---|---|---|
| Quick comparative QC screening | Good fit | Good, but may be more than needed |
| Better outdoor correlation | Limited (no dry-off cycle) | Stronger (wet/dry + humidity options) |
| Automotive/OEM cyclic methods | Typically not sufficient | Designed for it |
| Test workflow (single chamber automation) | Continuous fog only | Multi-step programmable |
Practical tip: If your failures happen after storage, transport, or intermittent exposure, cyclic methods often reveal issues that continuous fog can miss.
Q-FOG salt spray & cyclic corrosion test chambers available in Malaysia
We supply Q-FOG chambers commonly specified for ASTM B117, ISO 9227, and cyclic corrosion protocols. The selection below helps Malaysian QA/R&D teams match chamber capability to the standard and corrosion mechanism of interest.
Cyclic Corrosion Testing (Why it’s used)
Conventional salt spray (continuous fog at ~35°C) is widely used, but it may not mimic natural wet/dry cycles. Cyclic corrosion testing alternates between corrosion environments to better simulate outdoor exposure.
In a Q-FOG cyclic corrosion tester, specimens are exposed to programmed cycles such as salt fog + dry-off, and (for more advanced methods) humidity/condensation phases. Complex cycles can be automated using the chamber controller to reduce operator variability.
Model SSP (Salt Spray + Prohesion)
- Supports ASTM B117 and ISO 9227 (NSS)
- Supports Prohesion (ASTM G85 Annex 5)
- Suitable for comparative testing of plated/painted finishes and maintenance coatings
Model CCT (Salt Spray + Prohesion + 100% RH)
- Adds 100% humidity for cyclic automotive-style methods
- Enables multi-step cycles in a single chamber
- Can run more aggressive methods such as CASS (e.g., ASTM B368 / ISO 9227 CASS) where required
Models (Chamber volume options)
- SSP-600: conventional salt spray + Prohesion, ~640 L
- SSP-1100: conventional salt spray + Prohesion, ~1103 L
- CCT-600: salt spray + Prohesion + 100% humidity, ~640 L
- CCT-1100: salt spray + Prohesion + 100% humidity, ~1103 L

How to select the right salt spray tester in Malaysia
To avoid mismatched specs (and re-validation later), selection should start from the standard and the real failure mode you are trying to predict.
Quick selection checklist
- Standard: ASTM B117 / ISO 9227 / ASTM G85 / OEM cyclic
- Test severity: NSS vs AASS/CASS vs cyclic
- Specimen size: panel size, racks, throughput per cycle
- Workflow: single-chamber automation vs manual movement
- Utilities: water quality, drain, ventilation, power
Common “wrong-fit” scenarios
- Choosing NSS when the spec actually requires cyclic wet/dry + humidity phases
- Underestimating specimen throughput and needing a larger chamber volume later
- Not planning for documentation needs (QC trending, audits, OEM reporting)
Need a recommendation for your Malaysian site?
Share your target standard (ASTM/ISO/OEM), specimen size, and daily throughput. We’ll recommend the suitable SSP/CCT model and setup approach.
