The Model RC-27P High concentration Residual Chlorine meter provides an instant measurement of residual chlorine by the use of a polarographic sensor. It is mainly designed for use with chlorine or sodium hypochlorite disinfection water and used for measuring the disinfection concentration of free hypochlorous acid wash solutions commonly used for cleaning and disinfection of water supply lines or food and produce. This unit is very
similar in operation to the RC-24P, but uses a modified sensor for an
extended range of measurement. (20mg/L up to 300mg/L). A unique beads polishing system incorporated at the electrode system maintains the electrode in good working condition, free of interferences at the gold microelectrode, and ensures stable measurement. The meter also indicates the sample temperature and includes a built-in-clock. The instrument can store one set of results (measurement, temperature and time) in memory for later retrieval. Power is provided by two standard AA batteries which have an operating life of up to 50 hours.

| Note: Extract from produce may cause measurement error in wash solution after washing sample. Certain samples may not be able to be measured if reducing agents are present such as tannins, or significant dirt and mud is present. High concentration of hypochlorous acid, electrolysis solutions of hypochlorous acid, and strong acid solutions cannot be measured. |

What is Residual Chlorine ? Testing for Residual
Chlorine is very common in water treatment. The word, "residual", means
remainder or that which is left. This test is made to measure the amount
of chlorine remaining in the sample at the time the test is made.
Why Measure Residual Chlorine ? Chlorination has long been the conventional method for disinfection as it is effective and inexpensive. One must ensure the water wash system has a suitable concentration of chorine for a suitable period of time to ensure effective inactivation of bacteria and viruses. These checkpoints are typically monitored by small hand held devices. The advantage of DKK-TOA's Model RC-27P is that it can store data for later retrivel and it does not require any reagents to perform its measurement. Increasingly stringent requirements, growing awareness and understanding of the effects of chlorine on the environment, product quality and greater need for process optimization are strongly prompting many companies to more fully optimize the performance, reliability and safety of their chlorination programs. |
