The RC67-Series Free Chlorine electrode is an excellent choice for continuous measurement of residual chlorine in swimming pools, spas, industrial applications, or dirty/colored samples where colorimetric methods are inadequate. The electrode will fit many existing flow cells and uses a three-electrode amperometric measurement technology. The measured chlorine concentration is proportional to the output (0-5V or 4-20 mA), which is compensated by an internal temperature sensor. It is primarily intended for free chlorine analysis, but can also be calibrated for use in total chlorine determinations.

Features:

1-inch compression fit - fits the ASI Flow Cell or many industry standard flow cells
