Ethylene oxidegas detectorIt is a single-gas detection alarm with flexible configuration and can detect the temperature and humidity of the indoor environment at the same time. It has 500 sets of data storage, equipped with USB interface, can be connected to a computer, and has high accuracy. It has a very clear color touch screen, sound and light alarm prompt, and a built-in pump to ensure the detection of dangerous gases in a very unfavorable working environment and prompt the operator to take precautions in time. It is suitable for continuous in-line detection of ethylene oxide concentrations in various industrial and special environments. Imported electrochemical sensor and microcontroller technology are adopted. It has the advantages of stable signal, high accuracy and good repeatability. The explosion-proof wiring method is suitable for all kinds of hazardous places.
Test method:
1. Take an appropriate amount of ethylene oxide standard solution and prepare 6 concentrations of standard solution. Take 10 ml of each solution and prepare 6 concentrations of standard samples.
2. When the standard sample reaches vapor-liquid equilibrium, different concentrations of liquid correspond to different concentrations of gas. The equilibrated gas is taken and injected into a syringe to record the peak height of the ethylene oxide.
3. According to the peak height corresponding to different concentrations of standard solution, draw the peak height concentration of 1.5, and calculate the residual amount of ethylene oxide according to the formula.
Ethylene oxide gas detector performance characteristics:
1. Large screen LCD Chinese display, real-time display of temperature and working conditions, clear and intuitive value, real-time human-machine dialogue;
2. Power-on self-test, large-scale self-diagnosis function, accurate fault location judgment, alarm;
3. Six-channel independent temperature control (evaporator and capillary evaporator can be controlled independently), 16-step temperature programming function;
4. Over-temperature protection function: any channel exceeds the set temperature, the instrument will automatically power off and alarm;
5. The unique vertical heating device makes the evaporation of the sample more reliable, reduces the heat radiation generated by the evaporator, and ensures the minimum temperature deviation in the column box;
6. The intelligent fuzzy control rear door opening system can automatically track the temperature, dynamically adjust the damper angle, and realize near-room temperature operation;
7. Capillary shunt non-split injection device and gas sampler with diaphragm cleaning function can be installed.
