Hanna Anionic Surfactants Portable Photometer-Meter Only - HI97769

Hanna HI97769 Portable Photometer is a high-performance, precision instrument engineered for rapid and reliable determination of anionic surfactants in water and wastewater samples. Designed for professional laboratory, industrial, and environmental applications, this photometer delivers accurate measurements across a range of 0.00 to 3.50 mg/L (as SDBS), making it ideal for monitoring detergent concentrations and wastewater discharge quality.

Equipped with an advanced optical system, the HI97769 incorporates a reference detector, a 610 nm LED light source, and an 8 nm narrow bandpass interference filter. This ensures exceptional measurement stability, high sensitivity, and repeatable results. The system operates in accordance with US EPA Method 425.1 and Standard Methods for Water & Wastewater (20th Edition, 5540C), providing confidence in regulatory compliance and analytical accuracy.

The photometer is designed for ease of use, featuring a built-in tutorial mode that guides users step-by-step through testing procedures, reducing operational errors and improving efficiency. With no warm-up time required, users can perform immediate measurements, making it highly suitable for both field and laboratory environments.

A large 128 × 64 pixel backlit LCD display ensures clear visibility of readings in all lighting conditions. The instrument also includes onboard memory capable of storing up to 50 readings, supporting data logging, traceability, and quality control processes.

Built for durability, the HI97769 features an IP67-rated enclosure that protects against dust, water, and high humidity, allowing reliable operation in harsh industrial and environmental conditions. The unit operates within a temperature range of 0 to 50°C and up to 100% relative humidity.

Powered by three AA alkaline batteries, the photometer can perform 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) further conserves battery power.

Supplied as a meter-only unit (cuvettes, reagents, and accessories sold separately), the HI97769 integrates seamlessly into existing workflows. It is widely used in wastewater treatment plants, industrial process monitoring, environmental testing, and detergent analysis in commercial and municipal applications.
