Combined electrode ESK-10315/7 (glass)
Combined electrode ESK-10315/7 (glass) General purpose glass laboratory pH combination electrode with reservoir for increased electrolyte supply. The combined glass electrode ESK-10315 (laboratory) is designed together with an electronic converter (for example, an ion meter or pH meter) for measuring the activity of hydrogen ions (pH) in aqueous solutions. The electrode is a general purpose instrument for use in scientific and industrial analytical laboratories. Suitable for laboratory and semi-industrial installations for various purposes. The presence of a pipe on the electrode body allows you to connect an external container with electrolyte (KCl solution for the built-in reference electrode). Particularly recommended for measurements at elevated temperatures, as well as for the analysis of highly alkaline solutions with a high content of Na+ ions. Cable and connector: K 80.7 – cable length – 80 cm, BNC connector Manba: https://www.nv-lab.ru/catalog_info.php?ID=8452
