Combined electrode ESLC-01.7 (glass)
Glass combined pH electrode ESLC-01.7 ESLC-01.7 is a laboratory combined electrode designed for measuring the pH value of aqueous solutions and other liquid media, complete with secondary converters (pH meters and ionomers). It is used in analytical laboratories of industrial enterprises, in agricultural, environmental, scientific and other laboratories. Supplied with initial verification. The upper limit of the linear range of the hydrogen characteristic is indicated for solutions with a sodium ion concentration not exceeding 0.1 mol/dm³. Temperature range of the analyzed medium from 0 to 40°C The deviation of the hydrogen characteristic from linearity in the linear range is no more than ±0.2 units. pH. The slope of the hydrogen characteristic in its linear part upon release from production is in absolute value no less than 53 mV/pH at a solution temperature of 20°C. The values of the same parameter after operating for 500 and 1000 hours are no less than 51 and 50 mV/pH, respectively. The electrical resistance of the glass (measuring) electrode at a temperature of the analyzed medium of 20°C is no more than 100 MOhm. The electrical resistance of the internal reference electrode at a temperature of the analyzed medium of 20°C is no more than 20 kOhm. Overall dimensions of the electrode: glass part diameter 6 mm, length 160 mm, connecting cable length 1000 ± 50 mm. The weight of the electrode with cable is no more than 55 g (without bottle). The electrode is a single-function non-renewable product. The assigned technical life of the electrode is 1000 hours. Manba: https://www.nv-lab.ru/catalog_info.php?ID=5316
