DWS-295

Nano ion concentration meter

DWS-295The sodium ion concentration meter is mainly used for the determination of trace sodium ion concentration in water samples such as feed water, steam, condensate water, etc. of desalination water boilers in power plants; It can also be used in higher education institutions, research institutions, petrochemical, microelectronics and other departments to determine the concentration of sodium ions in natural, boiler water, industrial wastewater and other water samples.

·Adopting microprocessing technology. Dot matrix LCD display, Chinese operation interface

·It has functions such as automatic calibration, automatic temperature compensation, and automatic calculation of electrode slope

·The countermeasures and results can be stored, deleted, viewed, and printed for processing. Maximum storage capacity50Set measurement data; And provide two printing modes for users to choose from: instant printing and storage printing

·The instrument adopts a three electrode measurement system and haspNaValue and temperature valuemVDual display of value and temperature value or sodium ion concentration value and temperature value

·It has power-off protection function. In the event of shutdown or abnormal power failure after the instrument is used up, the measurement data and set parameters stored inside the instrument will not be lost

·Instrument withRS-232Interface, can be connectedTP-16Print measurement results with a serial printer or communicate with a computer
