pH meter TAN-1 (potentiometric)
pH meter TAN-1 (potentiometric) Designed to measure the activity of hydrogen ions pH and redox potential with simultaneous temperature measurement, it has a color touch screen that provides simple online control of the pH meter, and measures pH and redox potential using a combined electrode (with a BNC connector). Ease of use of the TAN-1 pH meter: Operating the analyzer is simple and intuitive thanks to the large touch panel. The setting is carried out by selecting the required measurement method and the combined electrode used in the pH meter menu. Measurement parameters for the selected methods and characteristics of the electrodes are stitched into the analyzer’s memory. It is possible to create new measurement methods, enter the parameters of new electrodes and save them in the pH meter’s memory. Measurement results can be saved in the pH meter’s memory (up to 149 thousand results). When saving measurement results, the time and date of the measurements are recorded. The user can select the discreteness of the measured values (from one to four decimal places). You can independently set the brightness of the display backlight, the backlight time (switching to “sleep” mode) and the time to turn off the pH meter if you are not working with it. Power is supplied from the built-in battery, from an external power supply or a personal computer using a cable via a USB connector. The power supply is included with the pH meter. Wireless charging of the pH meter is possible. The basic delivery set of a pH meter includes a combined electrode for measuring pH and a temperature sensor. The device is supplied with initial verification. Features and Benefits: color touch control panel; temperature-compensated pH measurement taking into account the coordinates of the isopotential point of the electrode used; the coordinates of the isopotential point of the electrode do not need to be entered manually, because they are programmed into the pH meter’s memory; constructing a calibration graph using 2-5 points and viewing the calibration graph in tabular and graphical form; linearization of the calibration graph and automatic exclusion of “dropped out” points. automatic calculation of the slope of the calibration characteristic of the electrode and comparison of it with the passport data for the electrode (diagnostics of the electrode operation); continuous operation time from the built-in battery is at least 13 hours.
