Product Description
Hanna HI97745 Portable Photometer is a versatile and high-performance multi-parameter instrument designed for accurate onsite measurement of key water quality parameters including pH, free and total chlorine, calcium, magnesium, total hardness, and low-range iron. Engineered for laboratory precision in a portable format, this photometer is ideal for environmental monitoring, water treatment, industrial testing, and educational applications.
The instrument features a sophisticated optical system incorporating a silicon photocell detector, a 525 nm LED light source with a narrow bandpass interference filter, and a reference detector. This advanced configuration ensures fast, stable, and highly repeatable measurements across multiple parameters, delivering reliable analytical results in both field and laboratory environments.
The HI97745 supports a wide range of measurements including pH (6.5–8.5 with 0.1 resolution), free and total chlorine (0.00–5.00 mg/L with 0.01 resolution), hardness parameters, and iron (0.00–1.60 mg/L). It operates using adapted Standard Methods (23rd Edition), ensuring compliance with recognized water testing protocols.
Designed for ease of use, the photometer includes a built-in tutorial mode that provides step-by-step guidance, making it suitable for both trained professionals and first-time users. The large 128 × 64 pixel backlit LCD display ensures clear readability in all lighting conditions, enhancing usability in challenging environments.
The device includes onboard memory capable of storing up to 50 readings, supporting GLP compliance and enabling efficient data tracking and reporting. The automatic shut-off feature after 15 minutes of inactivity (extended to 30 minutes before a READ measurement) helps conserve battery life and improve operational efficiency.
Built for durability, the HI97745 features an IP67-rated enclosure, offering protection against dust, water, and high humidity conditions. It operates reliably within a temperature range of 0 to 50°C and up to 100% relative humidity, making it suitable for demanding field applications.
Powered by three 1.5V AA alkaline batteries, the photometer can perform over 800 measurements without backlight, ensuring extended use in remote or continuous testing scenarios. It uses standard 24.6 mm round cuvettes for consistent and accurate sample handling.
Widely used in drinking water analysis, wastewater treatment, swimming pool monitoring, industrial process control, and laboratory education, the HI97745 provides a comprehensive solution for multi-parameter water testing.
