【Scope of application】:
Experimental instruments used to detect ethylene oxide residues.
[Instrument features]:
1、The instrument adopts a large LCD screen in ChineseLCD Chinese character display technology, intuitive display, easy to operate, more suitable for China’s national conditions。
2、self-diagnosis function,has“0℃”Protection function. When the temperature is displayed all the way, it is always “0℃”time, The heating will automatically stop in case the chamber is constantly heating and causing damage to the heating body.There are also Chinese prompts for the cause of the fault and alarm prompts。
3、The touch keypad allows users to set various operating data。
4、Data power failure protection function, the operation data set by the instrument can be stored for a long time after power failure。
5. Microcomputer control FID detector automatic ignition,With stopwatch timing function。
6、With over-temperature protection device. If the temperature exceeds the set, the instrument will stop heating and report a fault on the display。
7、The instrument parameters are intuitively displayed through the large LCD Chinese display,Through the user-friendly software operation interface,It is convenient for users to set parameters including temperature, process rise, detector, bridge flow and other parameters; Intuitively operatedSwitch bridge flow, turn on and off temperature control, turn on and off the process and various time events and other functions。
8、The instrument computer is connected to the Internet, and can be connected to the instrument through a remote computer to achieve remote data collection and management. Increases the freedom of the device and facilitates effective application in the laboratory 。
9、The main control circuit adopts advanced microprocessors and large-capacity memory to make data storage more reliable。 The integrated design of measurement, control, and power supply on one circuit board at the same time improves the interference resistance and reliability of the instrument。
10、The temperature control circuit of the microprocessor is adopted, and the temperature accuracy of the controlled objects in each heating area reaches 0.1degree。
11、The intelligent double rear door technology ensures that the temperature of the instrument column box has good temperature control accuracy and can quickly cool down。
12、The eighth order is programmed to heat up and is suitable for the analysis of complex samples with wide boiling points.
13、The unit-type overall structure design is easy to install and maintain。
14、Large volume column box that can be installed at the same timefourRoot Column。
15、The instrument design is reasonable and flexible, and three detectors can be installed at the same time, and there is an independent circuit system and signal output。
16、Flexible filling column and capillary column system,It can be connected to capillary columns of different calibers。
17、It has the function of air shut-off protection and Chinese prompt, which can be protected TCDThe tungsten filament and column are not damaged.
