Do you kown what is a salt spray chamber?

Salt Spray chambers are commonly used to evaluate the corrosive properties of:

1. Phosphated surfaces (with subsequent paint/primer/lacquer/rust preventive)

2. Zinc and Zinc-alloy plating (see also electroplating)

3. Electroplated chromium, nickel, copper, and tin

4. Coatings not applied electrolytically (such as zinc flake coatings)

5. Organic coatings

6. Paint coatings

Salt spray test chambers maintain two very precise temperatures during operation, which is crucial for consistent salt spray concentration and test item cover. The internal testing area is held at 35°C (95°F) while the external compartment is held at 45.5°C (113.9°F).

Working volume is defined as one-tenth of the measure of each axis toward the center of the test chamber. These minimum measurements are size-dependent and define the volume within the test chamber exposed to high precision temperature uniformity.

Temperature uniformity is made up of two averages: The temperature variation in space and the temperature gradient. Temperature variation in space is the average difference between the operating temperature in the middle of the test chamber versus multiple other discretionary points around the chamber.

The temperature gradient refers to the average difference in operating temperatures between those discretionary points around the test chamber. QINSUN ensures your devices will be tested with uniform, reliable, and repeatable environmental conditions.

Why choos QINSUN Salt Spray chambers ?

QINSUN's salt spray test chambers feature a high-reliability thermostatic temperature controller that maintains the salt solution at a preset temperature in a reservoir within a double-wall construction. The salt solution is introduced into the test chamber through an atomizing nozzle, which can be calibrated by QINSUN to perform to MIL-STD-19500B, paragraph 40.8, and other specifications.
