Test Chamber Options

  • Standard Salt Fog Testing Start Up Package - Includes the necessary collector funnels with graduated cylinders, one 50lb bag of salt, and one specific gravity hydrometer. All items comply with ASTM B117. Also available as individual items (Included with purchase a new salt fog chamber)

  • External Condensate Collection Package - Provides external sampling of fog condensate collection without opening chamber or interrupting test. Complete with two condensation collector assemblies mounted externally on stand and piped to collector funnels mounted in exposure zone.

  • Flanged Access Ports - Allows access to specimens while under test. Industry standard 2", 3", 4", 6", and custom sizes available. Includes a bolted plastic cover to seal the port when not in use.

  • Reverse Cover Opening - Control Panel and Humidifying Tower on left side of cover opening. Ideal for side-by-side placement or units facing each other.

  • Insulated Shell - For operating temperature above 120° F. - 140° F, or SWAAT Testing. Interior protective lining. 1/8" thick semi-hard natural rubber.

  • Ontario Hydro Wiring Package (Canada Only) - Wiring to conform to Ontatio Hydro Wiring Standards.

  • Re-circulating Exhaust Condenser System - System condenses and collects chamber exhaust into a separate 24 gallon reservoir mounted on Level-Matic® stand. System is completely self-contained, no outside vent required.

  • Drain Pump Out System - Convenient drain system when no floor drain is available. Connects chamber drain to an automatic condensate pump with tubing. Waste solution is then pumped to a 45 ga. drum with lid and drain that is mounted on a dolly with casters. Can be easily rolled to the nearest drain to empty.

  • CALgrafix GUI interface Software - Allows connection to a PC for easy reporting and data export

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.

Corrosion Test Chamber SCCH

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. 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. Often half the price of competitors' coupons. This consistency and uniformity is now available through Q-Lab's CX-series corrosion test coupons.

  • All CX-series corrosion coupons include a Certificate of Analysis
  • They come pre-cleaned, the production process thoroughly cleans the panels and removes any oil or contaminants that might be on the surface.
  • Corrosion coupons are often half the price of competitors' coupons
  • May have a shelf life of up to 10 years
  • Multilayer packaging, packed in plastic bags with vapor phase rust inhibitor and shipped in a sturdy cardboard carton
  • Ready to use right out of the package, 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.
