ammonium nitrate

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