pH meter / ion meter ITAN (stationary)
pH meter/ion meter ITAN (stationary) Designed for measuring the pH value, redox potential, ion concentration in drinking, natural, waste water, aqueous solutions of soil samples, food products, food raw materials using potentiometry. The ITAN pH meter/ion meter is an automated tabletop device, which includes: measuring transducer; color LCD display with touch control panel; magnetic stirrer (the magnetic stirrer is controlled automatically); electrode holder and temperature sensor (installed on a tripod with a foot). The operation of the ITAN pH meter/ion meter is controlled using the commands of the system menu displayed on the device display. Used electrodes: The pH meter/ion meter works with any type of ion selective electrode that has a BNC connector, including combination electrodes. Ease of use of the ITAN pH meter/ion meter: The pH meter/ion meter can operate either autonomously or under PC control (the software included with the pH meter/ion meter is specified at the order stage). In standalone mode, the device is controlled using a touch panel located on a color graphic LCD display. Thanks to the presence of a graphic display, the operator can view the calculated equation of the calibration dependence, as well as the dependence itself in the form of a graph or table. In automatic mode, the linearity of the calibration graph is assessed, “dropped out” points are discarded, and the slope of the electrode function is compared with its certified value for the electrode used (when measuring pH - a glass electrode). The type of electrode used and its characteristics are entered and stored in the analyzer's memory. Each action of the operator is regulated by the selected analysis method and is displayed on the screen of the pH meter/ion meter. To obtain an accurate analysis result, it is enough to carefully follow the instructions of the device. The operator can use up to 50 analysis methods, the parameters of which are stored in the device’s memory. Advantages of ITAN pH meter/ionomer: Large color display (display size: 152x84 mm). Metal body, resistant to chemical and mechanical influences. Magnetic stirrer and electrode holder built into the device body. Ability to work with any type of electrodes, including combined ones. Temperature-compensated pH measurement. Possibility of constructing a calibration graph using 2-7 points (2-15 points when connected to a PC). Visualization of calibration graphs on the device display. Checking the calibration curve using (1-2) standard solutions. Monitoring the serviceability of the electrodes and the correctness of the construction of the calibration based on the slope of the electrode function. Automatic or manual termination of the measurement process after potential stabilization. Automatic calculation of the analysis result and its error characteristics based on two (four) individual measurement results. Storage of parameters of 50 measurement methods in the device memory. Saving analysis results in the analyzer archive. ITAN pH meter/ion meter meets technical safety requirements regulations of the Customs Union TR CU 004/2011 and TR CU 020/2011.
