Description
The HI701 Free Chlorine Checker® HC allows users to measure active free chlorine with speed, precision, and simplicity, replacing traditional chemical test kits. Free chlorine is essential for maintaining safe water in pools, spas, and food processing, while excess levels can damage reverse osmosis membranes and other water systems. By using the DPD reagent, the device creates a pink color change proportional to chlorine concentration, which is quantified by the handheld colorimeter.
Designed for convenience, the HI701 is small, portable, and single-parameter focused, making it ideal for water quality monitoring, environmental studies, and educational applications. Its LED light source (525 nm) and silicon photocell detector ensure accurate measurements, while the compact size and low weight (64 g / 2.25 oz.) allow easy handling. The device includes sample cuvettes, reagent starter kit, battery, and instructions for immediate use.
