Introduction to the Hf MicroTPI portable turbidimeter
Water clarity is an important determinant of the its condition and productivity. Turbidity is a measure of water clarity. Nephelometers measure the intensity of light scattered by contaminants such as suspended and colloidal matter like clay and silt, and microscopic organisms. Turbidimeters using the nephelometric principal compare the light scattered due to contamination with the light scattering from a standard reference suspension. The result is a measurement of turbidity in NTUs - Nephelometric Turbidity Units.

The Micro TPI is designed to provide the ease of portability needed in the field with rugged durability, this is an ideal instrument for anyone monitoring turbidity on the go. The shock-resistant carrying case holds everything needed for field operation while the instrument itself removes easily to go wherever you need it. With resolution of 0.01 NTU and an extended range to 1,100 NTU, the MicroTPI is a great instrument for field use.
The MicroTPI includes carrying case, one set of calibration standards, indexing rings, 4AAA alkaline batteries, operators manual and measuring cuvettes with light shield caps.
