Having clean and well-maintained moisture balance equipment is crucial to the accuracy of the readings it provides. If a certain process requires the ability to precisely maintain acceptable levels of moisture using a moisture analyzer, then it is important to establish and abide by a suitable maintenance program for the equipment itself. With a good maintenance routine that is regularly observed, you are not just extending the life of the equipment, you are essentially protecting an investment.
Moisture analyzers, otherwise known as moisture balance equipment, are incredibly sensitive tools that need to be kept clean, especially if you want to maintain their accuracy in measuring moisture levels. In a lab, for instance, moisture analyzers are ideally placed in a clean, protected area away from dust and other substances that could be detrimental to the equipment and may affect their accuracy and repeatability.
However, the lab is not the only place where moisture analyzers are used. There are many applications and processes that may require the use of such instruments; and some of the places that utilize moisture analyzers may not always have a clean and safe area or ideal conditions for such a sensitive tool. That is why having a good maintenance program is still necessary.
Additionally, when conducting moisture analysis, some of the samples being tested may end up spilling from the sample plate and onto other parts of the equipment itself. And certain samples, especially liquids and fine powdery substances, can present real hazards to the performance and condition of the equipment.
Moisture Analyzer Cleaning Tips
Before you start cleaning the instrument, you need to make sure that it’s unplugged from any power source. You then have to refer to the owner’s manual as to the manufacturer’s directions for the step-by-step cleaning process. Normally, you will be required to remove accessories and parts that can be detached from the equipment and clean those parts separately. The most common removable parts are the sample dish, the sample dish holder, the dish retainer, and the draft shield, as well as the base plate in certain models.
These parts can then be cleaned individually, using soft cloth dipped in soapy water. Make sure to wring out the cloth before you start cleaning the accessories. Use mild dishwashing liquid. Never use strong cleaning solutions, unless specified by the manufacturer. You then rinse the parts with a fresh piece of cloth dipped in clean water. Dry the accessories using a clean piece of dry, soft cloth.
As for the body of the equipment, the same caution should be applied. Remove any lose dirt or substances using a soft bristle brush or a handheld vacuum cleaner. Once the lose material has been successfully removed, you can start wiping down the surface of the equipment with your soapy water. Be careful not to let the solution penetrate the interior electronics of the instrument, so you have to make sure to wring the cloth first before you start wiping.
When cleaning sensitive equipment, it is always best to consult the user’s guide and refer to the manufacturer’s recommendations as to how you should clean the device.
