Description
Overview
GAOTek handheld multimeter pH measures six key water treatment parameters simultaneously: pH, conductivity, PTSA, Free Chlorine, ORP, and Temperature. Featuring simple, one-handed operation, the multimeter leverages proprietary technology combining electrochemical and optical measurements in a cuvette-less platform. With this you can view results in under a minute for all key parameters for a typical water treatment application such as cooling tower analysis. The multimeter logs a complete measurement history, which you can transfer via Bluetooth to your smart phone or PC for statistical analysis.
