Description
Overview
GAOTek portable 3 channels conductivity tester 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 IP67 robustness rating.
Features
- Smart sensors available to measure a wide variety of parameters including Total Dissolved Solids (TDS), Optical Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Temperature, Conductivity, and pH
- Smart probes are automatically retaining calibration history and method settings to minimize errors and setup time
- Deliver superior accuracy and response times –even when measuring challenging samples or challenging operating environments
- Offer a range in measurement versatility – eliminating the need for multiple pieces of equipment
