Four-Channel Volumetric Karl Fischer Moisture Titrator MKV-710M

Principle of Volumetric Karl Fischer Moisture Titrator
Karl Fischer reagent (a solution composed of iodine, sulfur dioxide, pyridine, and methanol or ethylene glycol monomethyl ether) can quantitatively react with water in the sample. The reaction equations are as follows:
H2O + I2 + SO2 + 3C5H5N → 2C5H5N·HI + C5H5N·SO3
C5H5N·SO3 + ROH → C5H5NH·OSO2·OR
The sample is dissolved in a suitable solvent (or the water in the sample is extracted), and titrated with Karl Fischer reagent of known titer. The titration endpoint is determined by the dead-stop method, allowing the mass fraction of water in the sample to be measured.

Main Features of the Four-Channel Volumetric Karl Fischer Moisture Titrator MKV-710M:

1. Equipped with a large 8.4-inch color LCD touch screen for operation and control.
2. Simultaneously controls four Karl Fischer moisture titrators and automatic potentiometric titrators.
3. The touch screen operates via wireless Bluetooth for enhanced safety and reduced risk.
4. The touch screen MCU-710 can be connected to a battery for portable operation.
5. User permission settings to prevent incorrect configurations and facilitate management.
6. New burette unit design reduces dead volume and reagent consumption.
7. Smart burette unit with reagent information stored in a chip.
8. Measurement results can be stored on a USB drive, and PDF experiment reports can be generated.
9. Compatible with the Karl Fischer oven ADP-611, automatically determining the optimal heating temperature.
