Instruments main features

(1) using the MCU technologies are aqueous solution (including electrolytes and water) automatic compensation of the temperature coefficient, and data accuracy;

(2) the instrument has two measurement channels (a, b), can be monitored simultaneously two different measuring points, particularly suitable for water treatment equipment for water pretreatment and effluent monitoring;

(3) large screen dot backlit LCD display can simultaneously display conductivity values of the two measurement points, users can choose according to their needs with temperature compensation pictures with and without temperature compensation measurement data of the picture. Select when there is a temperature compensated instrument for measuring the data value that is automatically converted to 25 ℃;

(4) two-channel (4~20) mA current signal output;

(5) with signals RS-232C standard UART communication function, intelligent instrument with RS-232C standard serial data communication, such as computer, printer, recorder, remote console, and so on. Supporting our DY-301A-type electrical conductivity (electrical resistance) rate of printers, you can print two measuring channels measuring data in real time, the print form is shown in Figure 1. Such as matching our communications software CD, you can be connected to the user's computer to implement communication and apply print save;

(6) the conductivity limit alarm function, can simultaneously control two channels;

(7) the instrument has two-channel electrode constant, temperature compensation coefficient, alarm set three parameters, the user can be modified according to the actual situation, while instrument with power failure protection functions;
