Product Description

The HI97731 Zinc Portable Photometer is engineered for laboratory, industrial, water treatment, and environmental field applications requiring accurate measurement of zinc concentrations. With a measurement range of 0.00 to 3.00 mg/L (ppm) and resolution of 0.01 mg/L, this photometer uses the Zincon method, adapting the standard methods for water and wastewater analysis.

The device incorporates a reference detector and 8 nm bandpass filter (575 nm) to provide extremely fast, repeatable, and reliable measurements. The built-in tutorial mode facilitates step-by-step operations, ensuring user confidence and minimizing errors. CAL Check functionality supports performance validation, while Good Laboratory Practice (GLP) features ensure traceability and compliance.

Superior optical system designed with LED light source and silicon photocell detector.
No warm up time is required, resulting in rapid and efficient workflow.
Automatic shut-off reduces unnecessary battery drain during field or laboratory use.
50-readings data logging memory assists with result traceability and reporting.
Large, backlit 128x64 pixel LCD delivers clear readings and menu navigation in all lighting conditions.
Robust construction rated IP67, suitable for use in demanding environmental and industrial settings.
Operates reliably from 0 to 50°C and 0–100% RH, supporting a broad range of working environments.

Typical applications include drinking water testing, industrial effluent monitoring, surface finishing, cooling tower treatment, and more. Operates on 3x AA alkaline batteries, providing up to 800 measurements (without backlight). The portable, lightweight design (380 g) enables convenient on-site and field analysis.

Dimensions (LxWxH): 142.5 x 102.5 x 50.5 mm. Compatible with 24.6 mm round cuvettes. For laboratory professionals and field technicians seeking reliable zinc analysis, the HI97731 is an essential solution.
