Salt Spray Chambers

New In Stock Equipment


Corrosive atmosphere chambers subject test items to corrosion without introducing other contaminants into the test area.

Our salt spray chambers are entirely self-contained. The basic chamber conforms to military specifications, including MIL-STD-810, and is also used for many commercial and ASTM specifications.

The MX-9200 Corrosive Atmosphere Chamber:

A high reliability thermostatic temperature controller maintains the salt solution at a preset controlled temperature in a reservoir within the double wall construction. The salt solution is introduced into the chamber through an atomizing nozzle. The nozzle can be calibrated by us to perform to MIL-STD-19500B, paragraph 40.8 and other specifications. This specification requires that a salt residue be deposited on the specimens, in addition to generating salt fog atmosphere.

The preparation of a salt solution consists normally of sodium chloride containing as a dry compound not more than 0.1% of sodium iodide and not more than 0.2% of total impurities. This solution is prepared by dissolving five parts by weight of salt in 95 parts by weight of distilled water. It is important to maintain this solution at a specific gravity of from 1.023 to 1.037. The solution is maintained at a controlled temperature of 95°F by the chamber's own integral temperature control system (temperature is adjustable).
