5.3.3. The Glass Fiber Sheets
Use the glass fiber sheet to measure the moisture content
that is included in the following samples. When this sheet is
used, vaporization of moisture is speeded up and moisture
measurement result becomes quick and precise.
This accessory (AX-MX-32-1) is a package of 100 glass fiber sheets.
This accessory is inclued in the packing for MS-70, MX-50 and MF-50.
Purchase this accessory by your order for ML-50.
Use the glass fiber sheet (AX-MX32-1) for high surface tension liquid sample.
Example 1 : "Liquid Sample" Or "Meltable Sample"
When the glass fiber sheet is used for these measurements, moisture is more apt to
vaporize because of expanding the surface area and space. And the glass fiber
sheet has the effect of preventing a surface film from forming at drying process.
A sample including a lot of moisture
: Milk, yogurt, soybean milk, condensed milk, ketchup, resin, liquid paste, hand soap, etc.
A sample that melts and adheres to the sample pan.
Example: Chewing gums, caramel, hony, etc.
Procedure (Preparation before heating)
1 Put the glass fiber sheet on the sample pan.
2 Press the RESET key to display zero.
3 Soak the sample into the glass fiber sheet or put the
sample on the glass fiber sheet.
4 Press the START key to start the measurement.
Example 2 : "If The Sample's Surface Is Apt To Carbonize"
When the sample is covered with a glass fiber sheet, carbonization of the sample surface
decreases. Therefore the measurement result becomes repeatable and precise.
A sample including a lot of sugar, protein and oil
Example: Hony, soybean powder, green tea leaves, cookies, etc.
A sample that has dark surface and is apt to carbonize
Example: Coffee, peanuts, etc.
Procedure (Preparation before heating)
1 Put a glass fiber sheet on the sample pan.
2 Press the RESET key to display zero.
3 Remove the glass fiber sheet.
4 Put the sample on the pan.
Cover the sample with the glass fiber sheet.
5 Press the START key to start the measurement.
