The Chlorine Tester is used for testing the resistance of pipes and fittings to a diluted chlorine-dioxide solution under increased pressure and temperature. The test cycles can last for months.

Specimens are mounted in one of four pressure regulated test lines. Each test line can support up to four specimens. The concentrated chlorine-dioxide solution is mixed inside the tester and then injected via a dosing pump into the test line.

The conductivity of the water is automatically regulated prior to dosing. Specimens are tempered inside an oven chamber during the entire testing process. Any gases and vapors produced during testing are dissipated by a central exhaust system.
