Combined electrode ESK-10312/7 (glass)
Combined electrode ESK-10312/7 (glass) Glass laboratory combined “semi-micro” pH electrode. The combined glass electrode ESK-10312 (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 device for use in scientific and industrial analytical laboratories. It is used for analyzing solutions in containers with a narrow neck (test tubes, flasks, bottles, etc.), as well as samples of small volumes (~0.2...0.5 ml). Preferred 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=8574
