Mitsubishi Chemical Portable Coulombic Trace Moisture Analyzer CA-31
name:Portable Coulomb methodMicro moisture analyzer
Brand:Mitsubishi Chemical Analytical Technology Co., Ltd
model:CA-31
Instrument features:
Based on Karl Fischer chemical reaction, the moisture content in samples can be measured from trace (ppm level) to constant (% level).
CA-31 is equipped with a 5.7-inch color LCD touch screen, allowing users to see all necessary information in one view without the need for excessive manual operation. The color LCD touch screen allows for clear and accurate viewing of the operation screen. Different colors display different measurement states, which can greatly improve operational efficiency.
3. The USB keyboard can be connected to CA-31 for easier input of sample names. For users who do not like to use touchscreens, all functions of the instrument can be controlled from the USB keyboard.
4. Easy to operate, users do not need to think about complex measurement processes, and can obtain results with just one click operation.
5. Portable design. CA-31 is not only a valuable laboratory equipment, but also suitable for on-site use. Configurable portable power bank, easily carried in a portable bag, suitable for various environments such as laboratories and manufacturing sites, without the need to choose a specific location.
6. Electrode with or without diaphragm can be selected:
--Diaphragm free electrode: can use a single component AQUAMION electrode solution, which is more convenient for daily fluid change and maintenance.
--Diaphragm electrode: capable of measuring a wide variety of samples, including ketones, low hydroxy acids, certain aldehydes, and other special substances.
7. Mitsubishi Chemical's full range of 7 moisture gasification devices can be connected to CA-31 to accommodate various samples such as powders, granules, pastes, lubricants, liquefied gas samples, etc. Not only does it greatly expand the scope of application of the instrument. Simultaneously providing accurate moisture measurement solutions for different industries.
8. The PC control software TV-31 will enable users to collect measurement results from CA-31 and use Microsoft Word ® Or Excel ® Format export report, titration chart, parameters, calculation formulas, etc.
9. This instrument can be used with Aquamicron ® Karl Fischer reagent can be used together, ranging from conventional double test forms, single test forms, as well as special formulations of oils and ketones. These reagents are developed together with instruments to achieve combined performance.
10. In addition, CA-31 comes in two colors; Samurai black and cherry blossom pink. Users should have some fun when choosing instruments, not just comparing specifications and prices
