GAOTek offers a wide selection of ion meters for precise calculation of number of ions in various kinds of solutions. These devices determine whether the solutions have positive or negative ion charge. A solution of known concentration is accurately prepared, and its mV value is plotted on a graph of mV vs. concentration to determine the corresponding unknown concentration. These devices are durable and easy to use portable field instruments.


Ion meters help control the substances under evaluation, to ensure that a solution is properly measured for different purposes such as a variety of experiments in laboratories. GAOTek ion meters are capable of storing up to 500 data sets.


GAOTek ion meters are top notch when it comes to stability and accuracy. With different types of ion-selective electrodes for measuring a solution, the process can be carried out in an effective and efficient way.
