Main technical features:
1, the instrument adopts large-screen LCD Chinese character display technology, the display is intuitive, easy to operate, more suitable for China's national conditions.
2, self-diagnosis function, with "0ºC" protection function. When the temperature display of any road is always "0 ° C", the heating will automatically stop, in order to prevent the chamber from always heating and causing damage to the heating body. And the Chinese prompt fault cause and alarm prompt.
3. Touch keyboard is convenient for users to set various operation data.
4. Data power off protection function, the operation data set by the instrument can be stored for a long time after power off.
5, microcomputer control FID detector automatic ignition, with stopwatch timing function.
6, with overtemperature protection device. When the temperature exceeds the setting, the instrument will stop heating and the fault will be reported on the display.
7, through the large screen LCD Chinese display intuitive display instrument parameters, through the user-friendly software operation interface, greatly convenient for users to set including various temperature, Cheng rise, detector, bridge flow and other parameters; Intuitively operate the switch bridge current, open and close temperature control, open and close lift and various time events and other functions.
8, instrument computer connected to the Internet, through the remote computer and instrument connection, remote data acquisition and management. The freedom of the device is improved and the effective application of the laboratory is promoted.
9, the main control circuit uses the advanced function of the microprocessor, the use of large capacity memory, so that the data storage is more reliable. At the same time, the integrated design of measurement, control and electrical source of a circuit board improves the anti-interference and reliability of the instrument.
10, the microprocessor temperature control circuit, each heating area of the controlled object temperature accuracy of 0.1 degrees.
11, intelligent double back door technology, to ensure that the instrument column box temperature has a good temperature control precision, and can quickly cool down.
12, the eighth order process temperature, suitable for wide boiling point analysis of complex samples.
13, unit type overall structure design, easy installation and maintenance.
14, large volume column box, can be installed at the same time four columns.
15, the instrument design is reasonable and flexible, can install three kinds of detectors at the same time, and has an independent circuit system, signal output terminal.
16, Flexible packed column and capillary column system, can be connected with different caliber capillary column.
17, with the function of gas break protection and Chinese prompt, can maximize the protection of TCD tungsten wire and chromatographic column from damage.
