ION Meters

GAOTek offers a wide selection of different types of ion meters that are used to precisely calculate the number of ions in various kinds of solutions. It determines whether the solutions have positive or negative ion charge. The solutions of known concentration must be accurately prepared to determine the corresponding solution concentration. They are portable field instruments designed to be used in a simple, and suitable way and are durable for long-lasting use.

Ion meters helps control the substances being evaluated to make sure that the measurement of the solution is properly measured to use for different purposes such as experiments in laboratories. GAOTek ion meters are also capable of containing up to 500 data sets that help you to store a large amount of data and can be useful for future references.

GAOTek ion meters are top notch when it comes to stability and high accuracy readings. With the different types of an ion-selective electrode that are used to measure the solution, the process can be done in an effective and efficient way.

Technologies

The technology that is used to develop this product is the ion-selective electrode (ISE) also known as specific ion electrode (SIE). This device is a transducer or sensor that converts the activity of a specific ion dissolved in a solution into an electrical potential. For example, a pH electrode is an ISE for the Hydrogen ion. This potential is measured against a stable reference electrode of constant potential. Ion-selective electrode is mainly used in analytical chemistry and biochemical/biophysical research, where measurements of ionic concentration in an aqueous solution are required. The ion-selective electrode also consists of a thin membrane across which only the intended ion can be transported. Standard solutions of known concentrations are measured with the pH/mV meter.

Features

GAOTek ion meters are designed to be used in an easy and convenient way. They are portable, lightweight, user-friendly and are compactly made for a long-lasting use. This high quality low-cost devices are equipped with a large backlit LCD display with an English operation interface, which shows you all the information that you need and has 2 to 5 points calibration from low to high concentrations. System menu can be used to set 8 parameters, including the number of calibration points, stability condition and hold function. The elaborate measurement process is simplified by the direct ion concentration readout for a clearer understanding of the solution’s concentration. Multiple concentration units are also available such as ppm, mg/L, mml/L, and mol/L to keep track of the desired measurements that you want. The calibration due reminder also prompts you to calibrate the meter regularly to check the instrument’s accuracy. In addition, the current measurement status is automatically shown so you won’t miss any single detail. An auto-hold function is also included to freeze the stable reading for an easy viewing and data recording. Stored data can be transferred to a computer by USB communication interface and a built-in real-time clock stamps stored data to meet GLP standard. Help message as an operational guide for using the meter is available to help you quickly begin the process. Some offered products are also touch screen and have an mV range of -1999.0-1999.9 with an ion accuracy of ±0.5% F.S. The mV measurement mode also allows the user to check the performance of the ion selective electrode. Lastly, a long-lasting battery life for continued usage and to avoid work interruption.

Applications

Ion meters are mainly used in laboratories like medical, biochemical/biophysical research or school labs to collect data in making different kinds of solutions. The acquired data can be used in experiments and mixtures to produce different types of product. The accurately prepared known concentrations are measured with the pH/mV meter. Once the mV reading of each solution is noted and a graph of concentration vs. mV reading is plotted then the unknown solution can be measured. The typical response time for the reading to stabilize is approximately fifteen minutes when measuring standard or sample solutions. The outcome of the experiments made by these tools in the lab can improve our lives, our community and our work. It tests many different theories or hypothesis that scientists have. Most importantly it significantly advances the level our technology for a better standard of living.
