Corrosion Test Chamber SCCH

Salt Fog, CASS, Corrodkote, Humidity

Performs a wide range of accelerated corrosion tests including, but not limited to:
ASTM B117 (Salt Spray [Fog] ), ASTM B368 (Copper Accelerated Salt Spray), ASTM D1735 (Water Fog Humidity), ASTM D2247 (Condensing 100% Humidity), ASTM D1654 (Evaluation of Painted or Coated Specimens Subjected to Corrosive Environments), DIN 50021 (Salt [Fog] Spray), ASTM G85-[A1] (Acetic Acid- Salt Spray [Fog]), [A2] (Cyclic Acidified Salt Fog), [A3] (Acidified Synthetic Sea Water [Fog]), A4 (Salt/SO2 Spray [Fog]), and many others. {Note: optional equipment may be required}


Corrosion Test Chamber SCCH

ASTM D1654
  • Water jacketed design for uniform controlled test environment

  • Acrylic or Polypropylene Cover (model specific)

  • Easy to clean, seamless, polymer coated interior lining

  • Digital Temperature controls

  • Exposure zone wet and dry bulb

  • Humidifying tower

  • Data Logging for PC with communication control and software available




  • Cabinet: Painted exterior, water-jacketed design for more accurate temperature stability and control.
  • Interior Lining: High, performance, one-piece, seamless, oven-cured polymer lining. NO seams, NO glued on plastic sheets. Lower maintenance, higher durability, easier to clean.
  • Cover: Full view, acrylic cover with gas spring lifters - Models: SCCH20, SCCH21, SCCH22. Polypropylene with viewing window and pneumatic cover lifters: SCCH23 and larger
  • Comp-Test™ Digital Temperature Controls: Individual, constant, temperature displays for: (1) exposure zone dry bulb (2) exposure zone wet bulb and (3) humidifying tower. Allows for RH determinations at a glance. No switching required. Higher Accuracy ±0.1° temperature display in either °C or °F.
  • Comp-Test™ Air Flow Meter Instrumentation: Easy view meter showing the amount of air flow through the humidifying tower and atomization system. Provides more comprehensive monitoring capabilities of test functions and operations. Allows for immediate response to changes.
  • Comp-Test™ Dual Stage Compressed Air Control Pkg: (1) Oil and water extractor (filter), (2) High pressure regulator, and (3) Low pressure precision regulator combine to provide more accurate control of test conditions. Additionally act as fail safe protection for compressed air systems.
  • Level Matic® or Automatic Dl Water Fill System: Includes 10 gallon water supply reservoir with automatic Level Matic® (patented) solution level control system for humidifying tower, individual pressure gauge and 24 or 36 gal. solution reservoir on a stand (model specific) or Alternative Direct Dl Feed System available at no extra charge.
  • Low Water Cut Out Protection System: Safety feature automatically turns off the humidifying tower heater in the event of an interruption in the water supply. Resets when the water supply is restored.
  • Opti Fog® Generation Tower: Internally baffled for optimum fog generation for more accurate testing.

Corrosion Test Coupons


For over 50 years, Q-PANEL® test substrates have been recognized as the world standard for a consistent and uniform test surface for paints, plating, adhesives, sealants, rust inhibitors and other coatings.

This consistency and uniformity is now available through Q-Lab's CX-series corrosion test coupons. Corrosion test coupons ensure repeatability and reproducibility when performing laboratory corrosion testing. They help a user independently monitor the test conditions in the chamber by measuring the mass loss of the coupons as the test progresses. CX corrosion coupons are designed to meet the stringent requirements specified in many international modern corrosion test methods.

All CX-series corrosion coupons include a Certificate of Analysis, come pre-cleaned, and are ready to use right out of the package. This allows the user to simply weigh the panels and place them in the tester, saving time and effort. And best of all, CX corrosion coupons are often half the price of competitors' coupons.

Corrosion Test Chamber SCCH
The production process thoroughly cleans the panels and removes any oil or contaminants that might be on the surface. Steel panels are packed in plastic bags with vapor phase rust inhibitor and shipped in a sturdy cardboard carton. With this multilayer packaging, our steel panels may have a shelf life of up to 10 years. In most cases the panels can be used right out of the package. However, for critical applications it may sometimes be necessary to remove traces of the rust inhibitor with a distilled water or MEK wipe prior to coating the panel.

Quantity discounts are available. Please contact us for details.
  • Meets requirements of GMW14872, ASTM B117, SAE J2334, SAE J2721, ISO 9227, and VDA-233-102
  • Pre-cleaned and ready to use right out of the package
