dgf series electric drying ovens

feature

l         microcomputer pid control is used, with self-tunning pid function, make sure equipment can reach the best accuracy of temperature control at any working state.

l         enter parameters manually by pressing up and down key, the setting is simple and convenient, in the meantime, the set temperature and measured temperature are displayed.

l         convenient temperature compensation function can avoid the error between displayed temperature and measured temperature.

l         the products have function of timing constant temperature when the measured temperature has reached the set temperature.

l         with independent overtemperature protection device, reliability and safety of products are improved.

l         side heating is adopted, which will not damage the heater even dripping samples that are wet are dried, and it is easy to clean the oven body.

application

l         electronics, electrical engineering, instruments, material, semiconductor manufacturing enterprises do drying, baking, thermal insulation and heat treatment test on non-inflammable and non-explosive goods.

l         schools, biological pharmaceutical, food, cosmetics, tobacco, microorganism, chemical industry units do drying, baking and sterilization test on samples for research.

l         especially suitable for drying and ageing of products such as led, lcd, quartz crystal, optical fiber, capacitor, resistor, inductor during production process.
