MD50 Colorimeter – Chlorine Dioxide (Powder & Tablet Reagents)

The MD50 Chlorine Dioxide is a rugged, single-parameter colorimeter designed for accurate chlorine dioxide analysis in drinking water, wastewater, and industrial water systems. Supplied with both powder and tablet reagents, it uses the DPD/Glycine method to deliver fast, reproducible results in the field or lab. Ideal for disinfection control and regulatory compliance, this instrument combines precision optics with effortless data transfer and GLP-compliant logging.
