In order to ensure the quality of our products, develop new products and provide customer service, manufacturers should establish quality inspection institutions and laboratories to conduct necessary testing on products. To this end, it is necessary to be equipped with some test and detection instruments and tools. The following table lists the daily instruments and equipment used by latex paint manufacturers. It does not include more expensive or infrequently used paint testing instruments, such as artificial aging Test Chambers. Manufacturers with conditions should build constant temperature and Humidity Chambers to conduct product quality inspections in constant temperature and Humidity Chambers.
