DHG series dimensional rate of change tester and product details:

The temperature system of the instrument is manufactured by microcomputer intelligent digital technology, with industrial PID self-tuning and four double LED window display functions, high temperature control precision, strong anti-interference ability, and very convenient operation. The box is made of cold-rolled plate, the surface electrostatic powder spraying, the coating is hard and firm, and the rust prevention ability is strong. The studio is made of steel plate with rounded corners, smooth, smooth and easy to clean. The superfine glass wool insulation material is filled between the box and the studio, which has good thermal insulation performance, effectively ensuring the stability and accuracy of the temperature in the box and the impact on the use environment. The observation window of the door is a double-layer toughened glass structure, which can clearly observe the heated items in the box and has good thermal insulation effect. The box is designed with a reasonable hot air circulation channel, so that the temperature distribution in the box is more uniform and the temperature rises faster; The instrument is equipped with an adjustable outlet duct, which can adjust the amount of air in and out of the box. If the gas discharged from the box has odor or toxic, the air outlet pipe can be conveniently connected to another pipe to discharge the gas to the location.
