Hanna Silica HR Portable Photometer-Meter Only - HI97770

Hanna HI97770 Portable Silica Photometer is a high-performance analytical instrument designed for fast and accurate determination of silica concentration in water samples. With a measurement range of 0 to 200 mg/L (as SiO₂), this photometer is ideal for laboratory, industrial, and environmental applications, including monitoring silica levels in drinking water, natural water sources, and critical industrial systems such as boilers and high-pressure turbines.

The instrument features an advanced optical system incorporating a reference silicon photocell detector and a 466 nm LED light source with a narrow bandpass interference filter. This ensures highly accurate, stable, and repeatable measurements in accordance with US EPA Method 370.1 and Standard Method 4500-SiO₂. The precision optics enhance selectivity and reduce interference, delivering reliable analytical results across a wide range of conditions.

Designed for ease of use, the HI97770 includes a built-in tutorial mode that guides users step-by-step through measurement and calibration procedures, making it suitable for both experienced professionals and new users. The large 128 × 64 pixel backlit LCD display ensures clear visibility of readings in all lighting environments.

The photometer is housed in a rugged IP67-rated enclosure, providing protection against dust, water, and high humidity, making it suitable for demanding field and industrial environments. It operates effectively within a temperature range of 0 to 50°C and up to 100% relative humidity.

Additional features include automatic shut-off to conserve battery life and onboard memory capable of storing up to 50 readings, supporting data logging and traceability for quality control and compliance purposes.

Supplied as a meter-only unit (reagents, cuvettes, and accessories sold separately), the HI97770 integrates seamlessly into existing laboratory and field workflows. It is widely used in water treatment plants, environmental monitoring programs, industrial process control, and research laboratories where silica monitoring is essential to prevent scaling and equipment damage.
