Hanna Chromium (VI) Portable Photometer-Meter Only - HI97723

Hanna HI97723 Chromium (VI) Portable Photometer is a high-precision analytical instrument designed for accurate measurement of hexavalent chromium (Cr(VI)) in water samples across industrial, environmental, and laboratory applications. With a measurement range of 0 to 1000 µg/L, this photometer is ideal for monitoring toxic chromium levels in processes such as metal finishing, electroplating, paint and dye manufacturing, ceramics production, and wastewater treatment, where strict regulatory compliance and safety standards must be maintained.

Engineered with an advanced optical system that includes a reference detector and narrow band interference filters, the HI97723 delivers fast, highly repeatable, and reliable results without requiring any warm-up time, ensuring efficient workflow in both field and lab environments. It utilizes an adaptation of the ASTM D1687-92 Diphenylcarbohydrazide method, providing laboratory-grade accuracy of ±5 µg/L ±4% of reading at 25°C, making it suitable for critical environmental monitoring and quality control applications.

The instrument is designed for ease of use and operational efficiency, featuring a large backlit 128 x 64 pixel LCD display for clear visibility in all lighting conditions. A built-in tutorial mode guides users step-by-step through the testing procedure, making it accessible for both experienced technicians and new users. The CAL Check™ function allows quick verification of instrument performance, ensuring ongoing accuracy and reliability. Additionally, the photometer supports GLP compliance with storage for up to 50 readings, enabling proper documentation and traceability.

Built to perform in demanding conditions, the HI97723 features a rugged IP67-rated enclosure that provides protection against dust and water, making it suitable for both indoor and outdoor use. It operates efficiently in temperatures ranging from 0 to 50°C and humidity levels up to 100%. Powered by three 1.5V AA batteries, the device can perform over 800 measurements without backlight, making it highly portable and suitable for extended field operations.

Widely used in environmental laboratories, industrial plants, water treatment facilities, and regulatory monitoring applications, the HI97723 offers a dependable combination of precision, durability, and ease of use. It is an essential tool for professionals who require accurate chromium (VI) analysis to ensure environmental safety, regulatory compliance, and effective process control Portable Photometers
