NC-801.NC-802.NC-801A Dynamic simulator Instrument of cooling water

These two types of instruments are developed on the basis of the national trade standard "Test Method for Dynamic simulator of Cooling Water''drafted by Shen Hongli general manager of this company. The instrument is composed of four parts: two sets of independent cooling tower systems, boiler, instrument cubicle and microcomputer . It is characterized by compactness, less space, high degree of automation ,complete functions and low price(about 3 times lower as compared with the equivalent products on the marker)etc. Considering that the user of this instrument has to ensure the continuous operation of over 13 days, two sets of instrument control systems and water pumps are required in order to interchange with each other .

control system
NC-801 type	Controlling of single-chip microcomputer and instrument. If the Single-chip microcomputer breaks down, you can change to instruments for further running.
NC-802 type	Controlling of industrial PC& single-chip microcomputer. If the industrial PC breaks down, you can change to single-chip microcomputer for further running.
NC-801A type	controlling of instrument
Type NC-802AB	This instrument is composed by Siemens PLC and Touch Screen for control and display core. It can directly connect with and control the plant's central control system. It can primarily measure the values of entrance temperature and exit temperature, heating temperature, pH, electroconductivity, corrosion rate, etc. It can calculate these important parameters for evaluation of water quality, such as the dirtiness resistance, concentration ratio, deposition rate and scale thickness, etc.
