The drying oven is a kind of equipment used for drying samples, which can be divided into two categories of electric blast drying oven and vacuum drying oven according to the different drying substances. Blast drying is through the circulation fan blowing hot air to ensure that the temperature balance of the box, vacuum drying is the use of vacuum pumps will be pumped out of the box of air, so that the box of atmospheric pressure is lower than the atmospheric pressure, so that the product in a very clean state to do the test, mainly used for drying the samples, but also to provide the temperature environment required for the experiment. Generally speaking, the temperature range of the blast drying oven is usually room temperature to 250 ℃, suitable for a variety of heating and drying needs, temperature fluctuations are usually within ± 1 ℃. In the selection of electric blast drying oven, the need for multi-stage heating, insulation control or control of the rate of heating, the need for optional programmable temperature controller. In addition, the size of the drying oven should also be determined according to the size and number of test items to ensure temperature uniformity.
The drying oven such equipment in the chemical industry, electronic communications, plastics, cables, electroplating, hardware, automotive, photoelectricity, rubber products, molds, spraying, printing, medical, aerospace and higher education and many other fields have a wide range of applications. With a power outage, dead state data loss and protection of parameter memory, call recovery function.
