Combined electrode ESK-10309/4 (glass)
Combined electrode ESK-10309/4 (glass) Glass laboratory combined pH electrode for general purpose with built-in temperature sensor (3 in 1). The combined glass electrode ESK-10309 (laboratory) in a plastic case 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 most laboratory analysis applications. 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 80.12 – cable length – 80 cm, BNC + RCA connector Manba: https://www.nv-lab.ru/catalog_info.php?ID=9136
