pH meter / ion meter TAN-2 (potentiometric)
pH meter/ion meter TAN-2 (potentiometric) Designed to measure: indicator of hydrogen ion activity pH; indicator of the activity of рХ ions (with the possibility of automatic recalculation into mass and molar concentration); redox potential; temperature (carried out simultaneously with the indicators indicated above); nitrate content using the double addition method (Gran method) according to GOST 34570-2019. It has a color touch screen that provides simple interactive control of the pH meter and measures pH and redox potential using a combined electrode. The TAN-2 pH meter/ion meter works with any type of ion-selective electrodes that have a BNC connector (bayonet-locking electrical connector), including combined electrodes. Ease of use of the TAN-2 pH meter: Operating the analyzer is simple and intuitive thanks to the large touch panel. Configuration is carried out by selecting the required measurement techniques and electrodes used. Method parameters measurements and characteristics of the electrodes are stitched into the analyzer’s memory. Yes the ability to create new measurement techniques, enter parameters for new electrodes and save them in the memory of the TAN-2 pH meter/ion meter. 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 the TAN-2 pH meter/ionomer includes combined electrode for measuring pH and temperature sensor. The device is supplied with initial verification. Features and Benefits: the ion content can be automatically calculated in the form of activity index (рХ), mass concentration (mg/dm3), molar concentration (mol/dm3); 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); ability to work with any types of electrodes, including combined ones; continuous operation time from the built-in battery is at least 13 hours; Scope of delivery: Name Quantity, pcs. 1.
