Description
Overview
GAO Tek’s pH meter is designed to measure the electric potential, pH, pX concentration and temperature value. It contains several concentration measurement methods, including direct reading of concentration, known addition, unknown addition, and GRAN method. The device also provides slope calibration methods such as one-point, two-point, multi-point and multi-addition calibration, and power failure protection. This instrument features a large LCD screen with touch keys and an English operating system. The RS-232 port is also provided and can be connected with TP-16 serial printer as well as PCs for transferring data. As an upgraded version of pH meter, GAO Tek’s pH meter can store up to 200 sets of mV, pH, pX and concentration measuring data.
