Lovibond® MD 100 Colorimeter – Chlorine, pH, Cyanuric Acid, Alkalinity-m (Liquid Reagents)

This Lovibond® MD 100 is a 4-in-1 colorimeter designed for accurate testing of chlorine, pH, cyanuric acid, and alkalinity-m using liquid reagents for chlorine and pH and tablet reagents for stabilizer and alkalinity. With rugged waterproof construction and high-precision optics, it’s ideal for poolside, field, or lab use in water quality monitoring.

Also known as a photometer, this device supports disinfection, pH balance, stabilizer, and buffering capacity analysis using DPD, Phenol Red, Melamine, and Alka-M methods.
