The HANNA HI-97711 Free and Total Chlorine Portable Photometer is a high-precision handheld colorimeter designed for fast, accurate measurement of chlorine concentrations in water. Built with an advanced optical system featuring a reference detector and narrow band interference filters, this instrument delivers exceptional accuracy, repeatability, and reliability for both field and laboratory applications. It is ideal for monitoring chlorine levels in drinking water, swimming pools, wastewater, food processing, and industrial water treatment systems.
This rugged, waterproof photometer measures free and total chlorine from 0.00 to 5.00 mg/L (ppm) using the internationally recognized DPD colorimetric method (EPA 330.5). The built-in reference detector ensures consistent light output by compensating for temperature fluctuations and power variations, resulting in stable and reproducible measurements. Its LED light source provides superior efficiency, low heat generation, and extended instrument life.
The HI-97711 features an intuitive backlit graphical LCD with virtual keys and tutorial mode, guiding users step-by-step through calibration and measurement procedures. The integrated reaction timer ensures proper reaction time, improving measurement consistency across different users and environments. The meter supports both powder and liquid reagents, offering flexibility and cost efficiency for routine chlorine testing workflows.
Designed for durability and portability, the HI-97711 is fully waterproof (IP67 rated) and suitable for field use. Its ergonomic design fits comfortably in the hand, while the sealed optical chamber protects against contamination and damage. Automatic data logging stores up to 50 measurements, and the GLP (Good Laboratory Practice) feature records calibration data for traceability and quality assurance.
