HI97770 Portable Silica Photometer is designed for measuring silica concentration in water from 0 to 200 mg/L as SiO2 with advanced optical and user-friendly features.
The HI97770 Portable Silica Photometer provides fast, accurate measurement of silica concentration in water samples ranging from 0 to 200 mg/L (as SiO2). Designed for laboratory, industrial, and environmental water analysis, this portable meter is ideal for the monitoring of silica in natural, drinking, and industrial water systems, including high-pressure turbine applications.
Featuring a superior optical system with a reference silicon photocell detector and an LED light source (466 nm bandpass filter), the HI97770 offers consistent, repeatable results according to the US EPA Method 370.1 and Standard Method 4500-SiO2. The robust construction, large 128 × 64 pixel LCD with backlight, and tutorial mode provide excellent usability for both routine and advanced measurements. The IP67-rated housing ensures durability in humid and rugged settings, while automatic shut-off and a memory for up to 50 readings boost operational convenience.
Typical industrial, laboratory, water treatment, and environmental uses include monitoring for silica deposits and scale formation, especially in boiler and high-pressure turbine water systems. Package includes meter only; cuvettes, reagents, and accessories available separately. Dimensions: 142.5 × 102.5 × 50.5 mm. Weight: 380 g.
