Overview

Portable Multi-parameter Water Quality Meter LMPWM-A11 is adapted with different modes for measuring quality of water on different parameters such as pH, ORP, conductivity, TDS, salinity. Its memory can store & recalls up to 500 sets of data. Due to its portable design, it is suitable for outdoor measurements i.e. on site water testing, remote area water testing & for research purpose. It is reliable and user friendly.

Features
