Free & Total Chlorine - Designed with application Specific Ranges
- Simple and Accurate
- Cal CheckTM Technology
Total chlorine is given by the sum of free chlorine plus combined chlorine: free chlorine combines with nitrogen to produce chloramine (combined chlorine). Chloramine is harmful for aquatic life and damages water treaTMent plants that use membranes for water purification (e.g. reverse osmosis), Therefore it is important to monitor the level of free and/or total chlorine often. The chloramine concentration in water depends on pH, temperature, the initial ratio of chlorine versus amine, chlorine demand and the time of reaction. Both forms of chlorine (free and combined) can exist at the same time, though they need to be measured separately. HI 95711: wide range for free and total chlorine. HI 95761: trace total chlorine for ionic-exchange membranes and resins. HI 95724: the same specifications of HI 95711 but uses liquid reagents. Finally, instrument validation is possible at any time with Cal CheckTM standard cuvets.
HI 95761, HI 95711, HI 95724 are supplied complete with 2 measuring cuvets, 9V battery and instructions. HI 95761C, HI 95711C, HI 95724C kit includes the meter in a rugged carrying case, Cal CheckTM standard and accessories. |
