SILICA TEST HI705 – Low Range Silica Checker HC by Hanna Instruments
The SILICA TEST HI705 by Hanna Instruments is a portable handheld colorimeter designed to measure low concentrations of dissolved silica in both freshwater and marine systems. Utilizing a fixed-wavelength LED light source and a silicon photocell detector, it delivers laboratory-grade accuracy in a compact, user-friendly format.
Silica (SiO₂) naturally occurs in water and, when not controlled, can lead to scaling in reverse osmosis systems and heaters, or brown diatom algae growth in aquariums. The HI705 provides a cost-effective solution for accurately monitoring silica levels and preventing water quality issues.
Designed as a more reliable alternative to visual chemical test kits, this Checker HC offers clear digital readouts in four easy steps.
