    เครื่องโฟโตมิเตอร์-ไฮดราซีน (Hydrazine Photometer 0- 400 µg/L)

    HI 93704

    Hydrazine Photometer with 470 nm LED

              Hydrazine is a liquid chemical substance normally used in high pressure heating plants because of its properties as an oxygen inhibitor. It is added to avoid scaling and corrosion in the plant itself.

    Hydrazine reacts with dissolved oxygen to yield nitrogen and water, so that hydrazine has the advantage over the sulfite treatment because it does not produce any dissolved solids in the boiled water.

    Hydrazine is also used in tanks, because it controls the growth of bacteria.

    High concentrations of hydrazine can create a reaction with ammonia, which may result in damage to parts made of copper.

    Determination of hydrazine contents in water has been made easier by HANNA® with the HI 93704, a microprocessor-based meter that provides quick and accurate measurements.
