A high and low temperature laboratory is a type of laboratory that has both high and low temperature functions. It can also alternate between high and low temperatures and program cyclic experiments. High and low temperature laboratories, also known as high and low temperature laboratories, high and low temperature constant temperature chambers, high and low pressure circulation chambers, etc. Mainly used for complex high and low temperature testing, such as hot testing, cold testing, and dry resistance testing, to monitor the reliable performance indicators of products. Applicable to third-party quality inspection and measurement, scientific research institutions, laboratories of higher education institutions, quality inspection departments of enterprises and institutions, as well as various industries of electrical and electronic components, finished or semi-finished products.
The high and low temperature experimental box mainly consists of a control panel, distribution panel, insulation layer, air supply fan, heater, and freezer combination. The main specifications can be divided into 6 standard sizes and 10 specifications with different conditions.
The controller can be connected to the computer through a LAN interface, and users can design programs, collect test data and records, call program execution, remotely control machine switches, USB and other functions on the computer screen.
Adopting multi wing air supply fans, strong air circulation, avoiding dead corners, and ensuring uniform indoor temperature distribution.
