Moisture Balance (Aluminum Dishes)/ Instrument for Moisture Determination

The moisture balance scales of the PCE series are particularly suitable for industrial or commercial use. This type of scale determines the combined weight of an object before the drying process. This is done through quartz glass emitters. Subsequently, the remaining dry substance is weighed and the exact humidity of a weighed moist mass is determined therefrom. The decreasing moisture content is shown on the display during the drying process. The Aluminum moisture balance scales are ideal measuring instruments for precise determination of humidity, dry substances, or of the consistency of volatile and solid substances and substances. In the industry, the moisture balance is used for the rapid analysis of pastes, coating compositions, adhesives, and wood materials, powders. Those are used during the production and the entry check of products. The high-quality system of these devices has all modern features. As a result, these instruments can also be used as highly accurate scales in addition to being used as a moisture analyzer. We also have handheld instruments for the determination of absolute humidity.

If you have any questions about moisture balance scales, you can contact us by telephone at number the high-quality system of these devices has all modern features. As a result, these instruments can also be used as very accurate scales in addition to being used as a moisture analyzer. We also have handheld instruments for the determination of absolute humidity.

We also have handheld instruments for the determination of absolute humidity. Our technical staff and engineers will be happy to advise you on these moisture balance scales and, of course, all other products that you can find on our website.

The versatile use of the moisture balance scales/ aluminum dishes for moisture balances is almost limitless. Whether you want to determine the moisture content of bulk material, powders, food, wood pellets, or pastes or slurries, you will always get the measurement result quickly and accurately. As an example you can see below some pictures of different test goods:

Suitable accessories are also available for the moisture balance: Software Kit (software and data cable) for the direct transfer of the moisture measured values to a PC, printer, fiber optic filter, external test weights for independent local re-calibration … U You can also calibrate the moisture balance scales by ISO 9000 in the laboratory and have them certified (optional / for example for the first order or annual re-calibration).

How to run a test on your OHAUS MB23

This section follows how to do a moisture analysis test by using moisture analyzer OHAUS MB23 and see the procedure followed step by step. There are main steps to do moisture analyzing test.

Testing steps:

For testing you need the following equipment:

Aluminum dish
Two pads
Draft shield
Pan support

Step 1:

Setting the equipment.

The procedure is as follows:

Place the draft shield in the chamber that has to be fit like a puzzle.
Make sure that the lid cut is on point.
Place the pan support in the draft shield.
Turn on the unit.

Step 2 :

Running a test:

The second step follows running the test using a standard liquid solution of 500ml PN 302600. You can also see it our website. It implies the following small steps:

Place the 90mm aluminum dish and 90mm fiberglass pads (PN 1090)on the testing chamber.
Push the T button on the right side on the device.
Pour about 2.5 g of standard solution to the glass fiber pads.
Run the test button again
A time-lapse in seconds can be seen running on the right bottom of the user interface screen.
You can change your test results setting by pushing the bottom on the left side of the screen. This can only be done during the running of test.
After 6 mins and 43 seconds, the result and time have taken to display on the analyzer screen.

Precautions:

One should be careful while lifting up the sample back as it could be hot due to the testing procedure.
Never use the sample again.
Always get yourself new dishes and new pads for testing.

OHAUS MB23 specs:

Specs are as follows:

Capacity 110g
Readability 0.01g
Result readability 0.1 moisture.

Moisture content in the materials: With the thermo-gravimetric measurement method, all parts of the material sample are included in the measurement that can change their aggregation state (eg due to evaporation during heating) and that are involved in the loss of mass of the material. The measurement of the moisture content of materials is not equated with the assumption that there is the pure moisture content in the material. This measurement involves all volatile substances such as alcohol, aromatic substances, organic-based thinner, and other substances caused by thermal decomposition. In thermo gravimeter, therefore, no distinction is made between water and other volatile substances.

More About Aluminum dishes for moisture balances

There are a few non-destructive measuring methods to be able to measure the moisture content of the material, but these measuring methods will not be further explained now. The use of halogen radiation in a moisture balance scale has a considerably shorter drying time for the user compared to a conventional drying oven method, in which a hot air stream heats the material from outside to inside and the moisture disappears. This saves you time and money.

Measuring principle of the moisture balance scales (in the version as a scale): Thermo-gravimeter – this method is based on the determination of the weight loss due to the drying process. The sample is weighed before and after drying. The difference between the mass of the material and the initial mass or final mass of the material is stored after drying.
