Product Specification

Multiparameter Water Quality Instrument?INTRODUCTION
The instrument is a portable device that can monitor three different water quality parameters simultaneously, including temperature, pH(ORP), and any one of Yosemite's digital sensors of dissolved oxygen, conductivity, turbidity, or chlorophyll sensors. The microprocessor based meter can automatically detect Yosemite's digital sensors and can measure, display, log, transfer, and perform sensor calibration easily on a single platform.

The instrument is designed for outdoor applications and it is an ideal solution for field measurement of water qualities in lakes, rivers and oceans.
