If the Ohaus MB25 is unavailable, your second option should be the Ohaus MB23.
Any R&D lab or quality control department would be incomplete without one of the best moisture analyzers as part of its equipment collection. What is a moisture analyzer? When developing new criteria or meeting new ones for established manufacturing, a moisture analyzer provides information on correct moisture content to help ensure that this factor is in accordance to established standards by regulatory authorities and industry trade associations. Now what sets apart a premium quality moisture analyzer from a mediocre one?
A suitable heating profile for your needs
When examining which of the products among those featured in the best moisture analyzer reviews is perfect for your lab, remember that in a moisture analyzer, different substances react variously to heat. Some moisture analyzers come with a fixed heating rate while others allow you to choose the heating profile that determines how heat is delivered to the sample. The heating profiles are generally set through trial and error but once this is done, can be stored in memory on the device and then recalled accordingly when performing analyses.
With standard drying, the sample is heated rapidly to the set temperature. This is a commonly used process thanks to its general suitability for most substances. Gentle or soft drying is designed for substances that don’t work under fast temperature increases or that have a tendency for crust or skin formation, which limits the drying process. You can adjust the rate at which the device reaches the set temperature.
With fast heating, sample testing can be accelerated especially with substances that have a moisture content between 5 and 15 percent. The temperature increase is achieved extremely quickly and can exceed the set drying temperature briefly, after which the temperature can be regulated down to what has been set before. Substances such as gypsum, that let free moisture go at one temperature and release bound moisture at a higher level,are perfect for the step drying process. With this system, the sample gets heated to the first selected temperature and held there for a specific amount of time, after which it is then heated to the second selected temperature. With step frying, you can select the individual heating increments. This heating profile is suitable for samples with at least 15 percent content.
Ease of use
How does a moisture analyzer work? The answer lies in how easy the device is to use. A moisture analyzer provides precise and accurate determination of a sample’s moisture content. Basically, you have to check the unit’s readout, also known as its readability or resolution. This refers to the smallest unit that can be viewed on the control panel and is presented in percent moisture and grams. On the other hand, the ability of the device to present the same result after the sample has undergone repeated testing is referred to as the repeatability. Expressed as a standard deviation, this value ensures the reliability of the device.
Once the moisture analyzer has been correctly assembled, you should be able to work comfortably when doing moisture analysis. Make sure the machine is level using built-in foot height adjustment screws and checking out the leveling bubble. Operation should involve at only a few simple steps. After turning the machine on and allowing it to warm up, you simply insert the empty sample pan and press the tare button. Then, load the sample and press a button to engage moisture analysis functionality. Some models have the rest of the moisture test, including the moisture test analysis recording and shutdown done automatically. Ideally, once the device gets to the operating temperature, it should be able to go into standby mode when not in use so you won’t have to warm it up every single use.
Erroneous readings can be avoided if the machine is easily calibrated by following instructions in the user manual. Some models need a separately bought calibration weight for this purpose. Recalibration is needed when the instrument is transferred to another location. It is also sensible to perform regular calibration tests.
The sample pan and heating chamber should be easy to load and clean up. If possible, the device should allow you to link it with a computer for convenient recording of results. Models with an RS232 bidirectional interface provide the solution for this requirement. Because accurate calculation of moisture content is vital both for ensuring quality control and the development of new products, the device should provide accurate readings that can be viewed on a convenient backlit LCD screen. Go for machines with a tough die-cast metal and ABS plastic housing that ensure durability for lasting use. You want the machine to be light enough for easy transportability and compact enough for problem-free countertop placement and storage. Some models come with different measurement programs to allow you to choose from manual, automatic, standard, timer and quick drying processes.
