JF-3 type trace water measuring instrument with Coulomb method

Coulomb method for trace water analyzer is by Daqing City, Instrument Manufacturing Co., Ltd. to absorb domestic and foreign each instrument, the newly developed, with the international advanced level of modern analysis instrument. According to the principle of coulomb titration, the series instrument adopts microcomputer automatic control, compared with similar advanced products at home and abroad. It has the advantages of high sensitivity, fast speed, short balance time, accurate and reliable analysis results. Is the oil, chemical, electric power, environmental protection, medicine, scientific research and other departments of the first choice of high-quality analytical instruments.

JF-3 based on the new design concept, to adapt to the international trend, using split design, automatic man-machine menu dialog, full keyboard operation, can be connected to the computer, data processing, storage in the special software operation, small size, high degree of integration of the line. With a strong blank deduction function, the electrolytic cell is designed to prevent moisture intrusion, which greatly eliminates the influence of humidity on the analysis process.

I will continue to launch a series of new products, in order to adapt to the needs of different types of users, more embodies the human nature of analytical instruments, intelligent.

Technical index:

By the electrolysis current: 400mA max.

By measuring range: 3 to 100 micrograms of Mg (water)

Resolution: 0.1 micrograms.

* accuracy: 3 micrograms of water + 20%, 10 + 10% micrograms of water, 100 micrograms of water + 1%,

100 micrograms of water above + 0.5% (without sampling error)

Functional characteristics:

This communication function: you can add electronic balance or computer; (JF-3 version 1.2)

* output: liquid crystal display, numerical micrograms of water potentials and electrolytic current measurement

This print analysis time, trace water, sample concentration and related numerical formula

This control system: MCU and computer control

* zero correction: powerful software blank function, ensure that 10 minutes of sample enrichment time, accurate deduction blank

According to the different sensitivity. The reagent, can be manually or automatically adjust the balance point, the optimal analysis process.
