Programmable constant temperature and humidity test chamber

Programmable constant temperature and humidity test chamber

发布时间:2020-08-18

This series of products are suitable for high temperature, low temperature, high and low temperature gradients of electrical and electronics, other products, parts, materials and various electronic components, as well as the use of performance and storage under damp and hot conditions where temperature cycles change and condensation occurs on the surface Sex. The products refer to the national standards GB10589 "Technical Conditions of Low Temperature Test Chamber", GB11158 "Technical Conditions of High Temperature Test Chamber", GB10586 "Technical Conditions of Damp Heat Test Chamber". (The specific performance parameters are subject to the technical agreement.)

This series of test boxes adopt a series of advanced and human-oriented design methods such as built-in surface humidification, unique cooling machine layout and heat dissipation, and front drawer type water filling, which bring great convenience to customers for use and maintenance. The control system adopts a large screen, large-capacity touch screen, full Chinese menu, friendly man-machine dialogue, simple program setting and operation. The controller supports USB2.0 interface, realizes computer data management through special software, and supports USB printer, mouse, U disk, and has data recording function (can be used instead of temperature and humidity recorder).
