DWS-803 Chinese desktop sodium Meter DWS-803 market the most powerful, the most convenient to use a sodium meter. Coupled with dedicated laboratory ppb level sodium measurement electrode and a reference electrode in a beaker static measurement of performance has greatly improved over conventional sodium table, just pay attention to cleaning the electrode in use, can get a more satisfactory results. Can be widely used for continuous monitoring of sodium ions by thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and running water. The main features of Chinese LCD, Chinese menu, Chinese notes. Microprocessor: the use of high-performance CPU chip, high-precision AD conversion technology and SMT technology, to complete the multi-parameter measurement, temperature compensation, self-test instrument, high accuracy, good repeatability. High reliability: board structure, touch buttons, no switch knob. Input impedance> 1012Ω. High sensitivity: the static water samples can be detected 0.2ppb (8pNa). Stable for a long time have a very stable reading. Design of water erosion. Electrode Diagnosis: variety of calibration methods, E0, S query performance monitoring electrodes. Network function: RS232 bi-directional communication, can be equipped with a printer or TLab1.0 communications and data processing software. Historical data: 3000 data storage. Notepad: 200 records information. Built-in real time clock: provide a time reference, and other functions. Industrial control watchdog: to ensure that the instrument will not crash.
