Product Description

Hanna HI97750 Potassium LR & MR Portable Photometer is a high-precision analytical instrument engineered for accurate and reliable determination of potassium concentrations in water across both low and medium ranges. With dual measurement capability of 0.0–20.0 mg/L and 10–100 mg/L (as K), this photometer is ideally suited for laboratory testing, agricultural nutrient management, greenhouse monitoring, environmental analysis, and industrial water quality applications where precise potassium control is essential.

The instrument incorporates an advanced optical system featuring a reference detector, a 466 nm LED light source, and an 8 nm narrow band interference filter. This configuration ensures exceptional measurement stability, high sensitivity, and repeatable results. It operates using an adaptation of the turbidimetric tetraphenylborate method, a proven analytical technique that delivers accurate potassium determination across a wide range of sample conditions.

Designed for both efficiency and ease of use, the HI97750 includes a built-in tutorial mode that provides step-by-step guidance through testing procedures, minimizing user errors and improving workflow efficiency. The integrated CAL Check™ function allows users to verify instrument performance at any time, ensuring consistent accuracy and confidence in analytical results.

The photometer features a large 128 × 64 pixel backlit LCD display, offering clear visibility of readings in all lighting environments. Onboard memory can store up to 50 readings with associated data, supporting GLP compliance, traceability, and quality control documentation in professional settings.

Built for durability, the HI97750 is housed in a rugged IP67-rated enclosure, providing protection against dust, water ingress, and high humidity. It operates reliably in demanding environments ranging from 0 to 50°C and up to 100% relative humidity, making it suitable for both field and laboratory use.

Powered by three 1.5V AA alkaline batteries, the instrument supports over 800 measurements without backlight, ensuring long operational life. The automatic shut-off feature after 15 minutes of inactivity (or 30 minutes before a READ measurement) helps conserve battery power and extend usability during extended operations.

The HI97750 utilizes standard 24.6 mm round cuvettes for consistent and accurate sample handling. Supplied as a meter-only unit (reagents sold separately), it integrates seamlessly into existing analytical workflows.

Widely used in water treatment plants, fertilizer solution analysis, agricultural irrigation systems, environmental monitoring programs, and research laboratories, the HI97750 provides dependable potassium measurement to support effective nutrient management and water quality control.
