MKC-710
Introduction
The MKC-710 you have purchased is Karl Fischer Coulometric Moisture Titrator, by which you can
measure micro amount of water content which exists in liquid or in solid sample material. The
measurement is easy to perform, fast in operation with its results of high precision and accuracy.
【 Features 】
1）Compact design
Burette drive unit is designed more compact than before and can be installed in A4 size.
2）Simple operation
Measurement can be performed with PRE-TITR. key and START key only.
3）Energy-saving designing
Power consumption was reduced by 30% compared with conventional models.
4）USB flash drive is designed at external control
The measurement result and the method are stored in USB flash drive, and data can be
managed as an electron record. Moreover, the measurement result can be stored as PDF
file, and the convenience of data has been improved. A keyboard for the input of number,
a barcode reader for the sample setting and a foot switch that can start to measure
without touching a device are installed as option. The working efficiency of measurement
improved for customer's usage
5）For several languages
Chinese (Chinese classics), Korean, Russian and Spanish are installed besides English and
Japanese.
6）GLP/GMP conformed
Operator names can be registered. And check results with standard substances can be
recorded.
7）Can be upgraded to high-end model.
Measurement by moisture titrator and potentiometric titrator can simultaneously be
performed by connecting with the MCU-710.
8）SOFT-CAP(option)
Data of Excel and CSV format can be edited directly by SOFT-CAP with PC.

Do not attempt overhaul or repair the
unit by unauthorized person except
authorized by KEM.
Danger of electric shock, fire or
malfunction.
Do not use the unit in a way other
than specified.
Danger of fire, electric shock or
malfunctioning of the unit.

1) Put a stirrer rotor into the cell, and install the inner burette, the electrode, desiccant
tube, the port plug and syringe inlet.
Note
Make sure to apply KF grease around glass sliding area.
Note
The seal on desiccant tube A on titration flask must be removed before
using.
Warning
When handling the inner burette, do not
hold the housing (black resin area) and sliding
area of desiccant tube in order to avoid breakage.

6) Install the desiccant tube onto the reagent bottle holder.
7) Place the reagent bottle in the bottle holder. If the outside diameter of
reagent bottle does not match the holder, use the bottle holder and bottle
stand as shown below.
8) Connect the tube for drain and injection to the Plug for titration flask as shown
below respectively.

Note
The bottle caps must be securely fixed in order to avoid air leak, which would
prevent the dispenser from working properly in suction and draining.
2) Connect the silicone tubes on both ends of desiccant tube, and put the tube in place as
shown below
3) Put the above 1) bottle in reagent bottle holder. If the outside diameter of solvent
bottle does not match the holder, use the bottle holder and stand as shown below.
4) Connect the silicon tubes, one to the top of solvent bottle.

5) Connect the tubes, one for draining to waste bottle and the other for injection to the two
bottles respectively.
6) Connect the drain tube to Cell and injection tube to the plug for titration flask.
7) Connect the drain tube to waste bottle and the drain tube to Cell to magnetic stirrer back
side pump.
8) Connect the silicone tube connected 2) to SOLVENT port on the rear panel of magnetic
stirrer.
9) Attach a filter to INTAKE port on the rear panel of magnetic stirrer.
Note
Please attach a filter to INTAKE by all means. In other words it might break down
in the electromagnetic valve in the flow when absorb dust.
