PASCO's ezSample™ water quality test kits simplify chemical testing of water sources--even for measurements requiring titrations.
PASCO's ezSample Field Titrators contain a vacuum-sealed quantity of titrant. The entire process requires only a minute or two, is completely portable, and avoids all the setup and cleanup associated with ordinary titrations.You won't believe how easy it is to get great results--even in the field.
This kit contains 30 individual Alkalinity tests and one Field Titrator.
The Water Quality Field Guide is designed around the use of the Xplorer GLX.
Water Quality Field Guide (PS-2829A)
A complete reference for all your water quality needs covering 16 water quality parameters, why they are important and how to accurately measure them.
