1 walk-in walk-in constant temperature and humidity chamber contents Humidity Chamber how the election, the product is good, the key is whether the test criteria are strict performance standards, product quality instrument Jane households rock solid, strict implementation of national and international standards . Large humidity test chambers suitable for computer motherboards, terminals, industrial controllers, power supplies and other microelectronic circuit components lifetime reliability tests. Performance indicators in line GB5170.5.-96 "electric and electronic products environmental testing equipment, basic parameters, test methods" requirement. Structural features 1 large environmental test chamber provides large parts industry, semi-finished products for temperature and humidity testing, which mainly consists of control panels, distribution panels, insulation library board, blowers, heaters, humidifiers, freezer combination, Main specifications distinguish seven standard sizes and 28 different indoor conditions test specifications. 2 by way of horizontal centrifugal air diffusion vertical heat exchange loop system to avoid dead ends so that the indoor temperature and humidity distribution. 3.IPC1000 controller can be connected by a RS 232 interface with a computer, users can design a program on your computer, collect test data and records, call program execution, remote control switch machine functions. 4 When an exception occurs, the controller screen displays fault conditions in a timely manner, cut off the power switch, and provides troubleshooting methods. 5. Freezer compressor imported from Europe and America, and use environmentally friendly refrigerant, low-temperature refrigeration systems using binary loop system design and use different compressors for power at different temperature fields in order to increase equipment life.
