... (nitrate, fluoride, chloride, bromide, iodide, potassium, ammonium, calcium, barium, silver, copper, sulphide, etc.), reference electrodes (single and double junction available), conductometry sensors and conductometers, desktop and portable pH meters, ion meters. We can produce pH electrodes of different lengths (for example, 30 cm). We are also able to design and produce custom industrial and laboratory instruments (constant pH mixing, large-scale titration automats...), industrial converters. We can write software (not only for our instruments) based on custom requests (Java, C#, Python, *SQL).
