By touching the metal of Model CA-200 without grounding, you can get an electric
shock.
WARNING
As it thunders, do not connect a power cable. Danger of an electric shock by lightning
CAUTION
Do not place things in front of Model CA-200. When things are placed, the power switch
of the unit can’t be turned off emergently and accidents can be caused.
CAUTION
Do not connect many cords into outlets. Danger of a fire by outlet overheat
CAUTION
Place Model CA-200 at the place free from water, humidity, dust, and oily smoke.
Danger of a fire, breakage, and an electric shock
WARNING
Model CA-200 is not explosion prevention, so do not place flammable material near
Model CA-200. The placement except these conditions causes a fire and
an explosion.
IMPORTANT SAFEGUARDS AND PRECAUTIONS CA-200
2
WARNING
After stopping the unit or at the parts change, repair, and inspection, pull off the main
power plug necessarily to avoid an electrical shock.
WARNING
Pull out a power plug while holding it not to disconnect or short-circuit in a plug or a
cord.
WARNING
Put on protective goggles and gloves necessarily when using reagents. Without putting
on them, skin disorder and blindness can be caused.
CAUTION
Do not impact exposed glass not to break it. Fragments and scatter cause accidents.
WARNING
Never disassemble or remodel the unit. Contact our distributors if necessary.
WARNING
When a trouble happens, immediately notify the fact to the person in charge and take an
emergency measure. If the cause is unclear or the problem is not solved, never restart the
unit.

CA-200 Section 1: Measurement Principle
1-1
Section 1: Measurement Principle
Model CA-200 measures moisture by applying Karl Fischer reaction to coulometric titration.
In this coulometric titration, supply electrolytic solution mainly composed of iodide ions, sulfur
dioxide, and alcohol to a titration cell. Iodine for titration is internally generated by electrolysis.
* Karl Fischer reaction
Water reacts with iodine and sulfur dioxide in base and alcohol.
H2O + I2 + SO2 + ROH + 3Base 2Base • HI + Base.....HSO4R (1)
* Coulometric titration
Iodine is generated from iodine ions by electrolysis in the anode solution containing iodine ions.
2I - - 2e I
2··········································································································································
(2)
When iodine generated by the reaction of the formula (2) is consumed according to the formula
(1), the consumption of iodine is detected by a detector electrode and iodine is generated again
from an anode by electrolysis according to the formula (2). The generated iodine is proportional to
electric quantity by “Faraday’s law”.
From the formula (1), the ratio of reaction of H2O and I2 is 1 : 1.
Therefore, 1 mol (18g) of water corresponds to 2×96500 coulombs and 1mg of water
corresponds to 10.72 coulombs.
Based on the above principle, moisture content is calculated from the electricity for electrolysis.

CA-200 Section 2: Installation and Assembly
2-5
2-1-2. Place for installation
(1) No large temperature changes, corrosive gas, dust, vapor, and direct sunlight
(2) The temperature should be 5 to 40 degrees Celsius and humidity should be under 80% without dew
drop.
(3) No electric and magnetic fields influence
POINT
Temperature change makes detection potential unstable and analysis accuracy
low. Direct sunlight causes liberation of iodine and analysis values are low.
2-1-3. Power supply
Connect a power cable apart from other units (large motors, dryers etc.) which generate noise.
In addition, connect it at the place where power change is within ±10%.
Use a 3P outlet with a ground or a 2P-3P adapter to ground firmly.
WARNING
If you touch the chassis metal part when an earth terminal is not grounded
completely, you get a shock.

2-2-1. Titration cell
Remove each part of a titration cell and spread lightly contacting parts with attached exclusive grease.
Put cotton balls and silica gel into a drying tube.
POINT
Necessarily use exclusive grease. Particularly when moisture adsorbs to the ceramic
septum of a cathode solution cell, much time is required until the widow condition
indication is stable. After leaving a cell in the air for a long time, dry it with a dryer and
assemble it.
(1) Put a titration cell to a stirrer stand so that a sample injection plug is at the front.
(2) Insert the BNC connector 1 of a detection electrode into the right connection jack (green). Insert
the BNC connector 2 of a cathode solution cell into the left connection jack (blue). Turn the cell
right to fix it.

2-2-3. Printer roll paper setting
(1) Take off a printer cover. Do not take off it forcibly.
(2) Cut the end of printer paper in a perpendicular direction to the feed direction. Put the paper from a
roll paper inlet so that the back of paper faces to this side.
(3) Raise a lever, pass paper so that printing side is downside, and lower the lever.
(4) Pass roll paper through the cover and set the cover.
Illustration 2-3. Printer roll paper setting
CAUTION
After paper setting, set a printer cover necessarily.
The cutter of a printer cover is sharp.
Take care not to get hurt at the setting.

3-6. Connection of optional units
CA-200 optional units are as follows. Buy them if necessary. Refer to each instruction manual for
details. By connecting various optional units, KF-200 application extends and efficiency improves.
3-6-1. CA-200 CH2 (channel 2)
CA-200 CH2 is useful when one more volumetric moisture meter is required.
By connecting a display, a keypad, and a printer, simultaneous measurement by 2 units is possible.
By pressing [Channel / Select] key, CH1 and CH2 display contents switch.
CH1 and CH2 available measurement modes and optional units are as follows.

Table 3-5. Measurement modes and optional units
*1. VA-200 or VA-210 can be connected to one CA-200. To connect the second unit, purchase
an optional CA/KF200 expanded power unit.
*2. To input sample weight into CH2 side by an electric balance, purchase an optional cable with
a switch for CA/KF200 balance connection.

3-6-2. KF-200 buret set
By adding a KF-200 buret set, a moisture meter is changed to KF-200 of volumetric titration.
KF-200 is useful for the samples containing much water and insoluble to electrolytic solution.
Up to 4 burets can be connected.
* When using more than 3 burets, purchase an optional CA/KF200 addition power unit.
3-6-3. Moisture vaporizers
For samples insoluble to electrolysis solution and containing interfering substances, water vaporizers
are required. We offer the following water vaporizers for your needs.

3-6-4. Electronic balance
Weight can be automatically inputted by connecting an electronic balance.
For connection and interface tests, refer to balance interface specifications.
3-6-5. Personal computer
Data can be processed by connecting a personal computer.
For format setting and interface test, refer to computer interface specifications.
3-6-6. Reagent supply and drain unit
Dehydrating solvent is supplied and drained automatically at KF-200 use.
3-6-7. Fritless cathode solution cell
A fritless cathode solution cell is used for CA-200 moisture measurement mode.
