Description
Overview
GAOTek Portable Multi-meter ph Meter is for water quality professionals who want to perform electrochemical analysis for field and lab environments. Our new portable platform will allow you to collect intuitive, accurate measurements, manage data, and easily review results, while supplying an IP 67 robustness rating. These meters offer a range in measurement versatility – eliminating the need for multiple pieces of equipment. We offer standard laboratory and rugged field smart sensors available with the sensor to measure a wide variety of parameters including Total Dissolved Solids (TDS), Optical Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Temperature, Conductivity, and pH.
