1.      Tính năng kỹ thuật:

-          The Residual Chlorine Meter, Low range, 0-2ppm provides a quick and easy measurement of free residual chlorine by the use of a polarographic sensor. The measurement can be achieved without the inconvenience and human errors associated with conventional reagent based portable instruments.

-          The New RC-31P has an expanded memory allows for the storage of 1000 results, upgraded software control program and the ability to use rechargeable batteries.

-          It is unique to other conventional models in that it uses no reagents and no membranes but is very accurate when compared against DPD for potable water. It can be calibrated against the colorimetric or titrimetric procedures within seconds.

-          The operational cost is extremely low and maintenance is simple.

-          The meter consists of two sections, a handheld keypad and a sensor assembly. The key pad section features a large, easy-to-read LCD panel. The sensor assembly is available in two versions, a grab sampler type and float suitable for field and grab applications, and a flow through cell suitable for tap water outlets and continuous flowing samples.

-          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.
