Description Overview GAOTek Analytical Laboratory PH Meter is a common laboratory precise meter which is also the upgrade product for original meter. This new pH meter has a newly designed shape, big LCD screen and clear display. The meter is added with automatic standard buffer solution distinguishing function which has the ability of distinguishing three different standard buffer solutions: 4.00pH, 7.00pH, 10.01pH. For easy use, a meter is also added with a necessary protection function as well as a reminder function. The meter is suitable for use in the laboratories of universities, research institutes and industrial enterprises for measuring the pH value and potential (mV) value of water solution. In addition, it can also be matched with ion selective electrode to measure the electrode potential of the particular electrode.
