Functional Features
It has the functions of determining water content by the Karl Fischer method and determining the acid – value and saponification – value indexes of chemical products.
It has an internal liquid – suction and – drainage device to ensure user safety during use.
It can automatically sense the addition of samples and start titration automatically.
With built – in standard methods, the instrument is ready – to – use once turned on. It has external extraction and blank – subtraction modes.
It has a high – resolution color touch – screen for directly viewing parameter settings and result information.
14 shortcut icons can be created on the touch – screen, and relevant experimental operations can be directly called by using the method.
USB disks can store anti – counterfeiting PDF experiment reports. This instrument can store 200 data sets, and USB disk storage depends on the USB disk space (20,000 sets (1G) or more).
Reagents are continuously monitored. Once the number of injections, the sum of amounts, or the total amount of injected water meet the self – defined limits, the instrument will automatically prompt the user to replace the reagents.
It has statistical functions (it can display the average value, relative standard deviation, absolute standard deviation after analysis is finished) and start – point, end – point, and drift – value adjustable functions.
It can connect to single – sample – position and multi – sample – position headspace – type Cassette Furnaces for heating, determining the moisture in non – soluble solids.
It can connect to printers, balances, computers, etc.
The steam – gas conduit has a heating function to prevent condensation.
It is suitable for the Karl Fischer method and volumetric methods.
The 885 – type fully – automatic Cassette Furnace has 18 sample positions and can realize automatic determination of sample blanks and sample water content.
