    The JBL phosphate test set PO4 is a means of exactly determining and routinely controlling the phosphate content in fresh water and marine tanks within a range of 0.05 - XXXXXX mg/l (ppm). JBL has developed a compensational method for slightly discoloured water. When e.g. peat is added to the filter or medical treatments stain the water, you will still get precise and reliable readings.

    • Determines the phosphate concentration in the water, which along with the nitrate concentration is responsible for undesirable algae growth
    • Messbereich beginnt schon bei 0,05 mg/l
    • For approx. 50 measurements

    • For fresh water and salt water
