Ion Selective Electrodes, ISEs, are analytical tools widely used for potentiometric analysis of large scale of various ionic analytes, using various procedures of measurement and evaluation. These sensors are ecpecially suitable for routine analysis being done in agriculture and food process, soil analysis, environmental samples, water, pot-, waste-, boiler-, mineral-, and well water samples, tribotechnical analysis, explosives and pyrotechnical mixtures analysis, various applications in research laboratories, biochemical process controll, chemistry and other education laboratories, and many others. Electrodes are applicable to all commonly used measuring apparatus, with internal resistance of above 10⁹, 10¹² for gas sensing ones respectively. Standard electrical connecting element is 0,8 to 1 mt. coaxial cable with BNC connector. The other possible connectors are SMS, SN6, DIN, CINCH, banana, SN6 (or S7) head connector and appropriate connecting cable. The work with ion selective electrodes is only a little time consumpting, requires an only small amount of chemicals, and a friendly price measuring equipment.

Silver metal electrodes have a pure silver, 99,99 %, sensor. Their applications are for argentometric coulometric or potentiometric titrations of chloride, bromide, iodide, cyanide, cyanate, sulfocyanide and other ion with slightly soluble silver salts. Electrodes are applicable to all commonly used pH-meters, titrators, coulometers and other analytical apparatus for argentometric titrations. Standard electrical connecting element is 0,8 to 1 mt. cable with banana, or BNC connector for combined electrodes. Others are as described above.

pH Electrodes are traditionally, for a very long period of time, nearly a century, succesfully used sensors for potentiometric determination of H+, respective H3O+ activity, expressed in commonly used pH units. These measurements are, perhaps, done in all fields of research, development, process, and in other human activities. Electrodes are applicable to all commonly used measuring apparatus with inner resistance of 10¹² or more. Standard electrical connecting element is 0,8 to 1 mt. coaxial cable, specially low noice, with BNC connector. Others are as described above. The electrodes with thermocompensation elements are equipped with multiwire coaxial cable and coaxial connector and banana, as for example DIN coaxial connector and banana for WTW pH meters.

Reference electrodes are commonly, very widely, used as the stable electric potential source for various electrochemical applications. Electrodes are applicable to all commonly used electrochemical apparatus. Standard electrical connecting element is 0,8 to 1 mt. cable with banana. Others are as described above. Reference electrodes for polarography are the ones, designed especially for use in stands of commonly used Metrohm, GAT, PolaroSensors and Ekom PA voltammetric analysers. Connecting elements are banana or microbanana.

Polarographic electrodes solid state, carbon, golg, silver and platinum working ones, argentchloride, calomel and mercurosulphate reference, platinum auxiliary ones, and a scale of combined electrodes. They are new fashioned, small size compact enbodied, very sensitive sensors, widely applied for voltammetric analysis of electroactive matters, like heavy metals, organic compounds, ions, and many others. Application of these devices includes analysis of agriculture, food, biological, biochemical and xenobiochemical, petrochemical, tribodiagnostic, environmental, metal industry, pharmaceutical, research samples, and many other analysis. Electrodes are especially constructed for extremly small or even no mercury consumption. Mercury or more electropositive analytes can be determined upon pure carbon or gold surface. Standard electrical connecting element is 0,6 mt. cable with bananas or microbananas. The electrodes are designed for application in Metrohm, PolaroSensors, Gamma Analysen Technik, PAR and Ekom PA apparatus stands or any others with 14 mm cones head of measuring cell and 50 or 80 mm active length.
