Similar to the Hi-95 series of instruments, Healthy Koi have recently introduced to their range, the new water resistant 96 Series of single parameter photometers. Using new technology with an advanced optical light system and ‘Cal Check’, these instruments with certified calibration and verification standards, bring in improved accuracy and versatility for the fishkeeper, especially for out of doors use. The instrument has been designed to accept large diameter cuvets (glass phials) making it easier to load the pond water samples and reagents. Powered by a long life battery , the ‘96’ Series also displays codes to aid the user in routine operations and include a low battery warning.
Total chlorine is given by the sum of free chlorine plus combined chlorine, where free chlorine combines with nitrogen to produce chloramines. Chloramines is harmful to aquatic life and damages water treatment plants that use membranes for water purification (e.g. reverse osmosis). Chloramines concentration in water depends on pH, temperature, the initial ratio of chlorine and amines, chlorine demand and total time of exposure. Both forms of chlorine (free and combined) can exist at the same time, though they need to be measured separately. HI 96761 is an auto-diagnostic portable photometer for accurately measuring trace total chlorine for ion-exchange membranes and resins. The advanced optical system employs a specialized tungsten lamp and a narrow band interference filter, assuring accurate readings between 0.000 to 0.500 mg/L. This instrument is equipped with Cal Check® validation function and standards to validate good performance at any time.
