DR-H304-160 Salt Fog Test Chamber
An approximately 800 L salt fog chamber with a 1600 × 1000 × 500 mm working space for corrosion testing of larger components and higher specimen quantities. Its corrosion-resistant PVC construction, continuous or periodic spray control and adjustable specimen rack support repeatable salt spray exposure for metals, coatings, fasteners, electronics and automotive parts.
What the “160” Configuration Provides
The “160” designation refers to the chamber’s 1600 mm internal width—not a 160 L capacity. With internal dimensions of 1600 × 1000 × 500 mm, the usable workspace is approximately 800 L.
This larger horizontal test area is intended for long panels, multiple coated coupons, automotive components, fasteners, electrical enclosures and other specimens that do not fit comfortably inside a small benchtop cabinet.
Aplicações principais
Coatings and plated metals
Compare protective coating systems and identify pores, discontinuities, edge corrosion, blistering or underfilm attack using an agreed exposure and evaluation method.

Expose fasteners, brackets, stamped parts, connectors and coated assemblies to a controlled salt fog environment before appearance, rating or functional evaluation.
Electrical and electronic products
Assess enclosures, connectors, terminals and metal hardware where salt-laden environments may contribute to corrosion or loss of electrical reliability.
Marine-related hardware
Evaluate materials, finishes and components intended for coastal or salt-exposed service under a repeatable laboratory condition.
Industrial quality control
Compare batches, suppliers or surface-treatment processes using the same specimen preparation, placement, exposure and acceptance criteria.
Research and validation
Support material screening and failure investigation when salt fog results are interpreted together with product-specific and field-performance evidence.

Provide specimen dimensions, quantity, weight, rack angle and a proposed loading drawing.
Set the exposure
Confirm duration, inspection intervals, interruption rules and required fog collection checks.
Confirm utilities
Verify power, compressed air, purified water, drainage and exhaust conditions at the installation site.
Define evaluation
State appearance, corrosion-area rating, mass-loss, functional or coating-adhesion acceptance criteria.

Confirm solution handling, ventilation and wastewater treatment requirements with the facility’s EHS team.
Installation and Utility Requirements
| Item | Planning requirement |
|---|---|
| Ambient environment | Recommended 5–30°C, ≤85% RH, level floor and adequate ventilation; keep away from heat, direct sunlight and strong vibration |
| Água | Use distilled or deionized water suitable for the governing test method and chamber steam/spray system |
| Compressed air | Clean, oil-free and stable air supply; confirm flow, pressure and filtration with the final utility drawing |
| Exhaust | Route corrosion-resistant exhaust safely outdoors with minimal restriction; the final route must follow DERUI’s installation drawing and local requirements |
| cURL Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits | Provide corrosion-resistant drainage below the outlet level and treat test waste according to local environmental regulations |
| Service clearance | Allow sufficient clearance around the cabinet for cover movement, solution filling, maintenance and electrical access |
Operation and Maintenance Priorities
- Prepare the solution and adjust pH using the procedure specified by the governing standard.
- Verify chamber and saturated-air temperatures before starting the formal exposure.
- Check fog collection at the specified locations and interval; do not infer compliance from pressure alone.
- Prevent specimens from contacting one another and avoid condensate runoff from one specimen onto another.
- Rinse the spray circuit and nozzle with suitable purified water after testing to reduce salt crystallization.
- Inspect air filters, seals, heaters, sensors, solution lines and safety alarms on a documented schedule.
- Use calibration and cabinet-corrosivity checks required by the laboratory quality system.
Perguntas Frequentes
Does “160” mean the chamber has a 160 L capacity?
No. It refers to the 1600 mm internal width. The 1600 × 1000 × 500 mm workspace is approximately 800 L.
Can the DR-H304-160 run continuous and periodic spray?
Yes. The controller supports continuous and periodic spray modes. The exposure sequence must still follow the selected test standard or customer specification.
What fog collection rate is specified?
The published specification is 1.0–2.0 ml per 80 cm² per hour. Operators should verify collection under stabilized conditions using the locations and procedure required by the applicable method.
Does it support NSS and CASS?
The supplied specifications include 35°C NSS and 50°C CASS chamber settings. Confirm the required method before ordering so the solution-contact materials, temperature settings and accessories are configured correctly. AASS requirements should also be stated explicitly when needed.
Is ASTM B117 a product pass/fail standard?
No. ASTM B117 specifies how to create and operate the salt fog environment. The relevant product or coating specification defines exposure time, specimen preparation, evaluation and acceptance criteria.
