Clarkson HI97712C
Aluminum Photometer Kit
Hanna Instruments HI97712C

HI97712 is an advanced, portable photometer for the measurement of Aluminum in water. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.

No warm up time before taking a measurement
Tutorial mode for step-by-step instructions
Display results in aluminum (as Al3+) or aluminum oxide(as Al2O3)

Significance of Use
Due to its vast occurrence in minerals, rocks and clays, aluminum is present in nearly all natural water as a soluble salt, a colloid, or an insoluble compound. These forms of aluminum may also appear in treated water and wastewater due to its use during coagulation processes. When concentrations are greater than 0.2 mg/L, water will be colored, but cause no significant human health effects.
