Overview
The walk-in sand and dust testing chamber provides the ability to simultaneously place a large number of test items for reliability testing, in order to shorten the total testing time of a single product, or to perform temperature and humidity stress screening (ESS) of the product, as well as dynamic testing that requires a large activity space. It is also suitable for products with large volumes.
Product Details

Walk in sand and dust test chamberFeatures:

The manufacturing capability of * can effectively control high temperatures at 80 ℃ and 100 ℃ to ensure stability;

Temperature and humidity execution capability range: 85 ℃, controlled humidity: 85% RH;

The laboratory has multiple alarm devices with remote wireless alarm function;

◆ Modular design, flexible combination, easy disassembly and assembly

Saisi adopts fully welded flooring, effectively ensuring a service life of over 20 years;

Adopting European and American compressors and servo cold coal flow control technology, effectively achieving low noise, low energy consumption, energy-saving, carbon reduction and energy-saving design;

The humidity water supply system of Saisi adopts a new RO reverse osmosis water filter automatic water supply device;

Equipped with RS232 data connection port and USB data storage and download function;

Walk in sand and dust test chamberMeet the standards:

GB/T2423.1-2008 (IEC60068-2-1:2007) Low temperature test method Ab;

GB/T2423.2-2008 (IEC60068-2-2:2007) High temperature test method Bb;

GJB150.3-1986 High temperature test; GJB150.4-1986 Low temperature test;

GB/T2423.3-2006 (IEC60068-2-78:2007) Constant humidity and heat test method Cab;

GJB1032-90 GB/T2423.34-2005 Temperature and Humidity Combined Cycle Test Method;

Equipped with advanced, reliable, and energy-saving refrigeration system equipment, adopting * refrigeration technology and equipped with cold end PID regulation technology (i.e. adjusting the refrigeration output through cold end PID regulation to achieve temperature balance during constant cooling and low temperature constant processes), the application of this technology not only reduces the compressor's refrigeration input power, but also greatly reduces the heating power, thus enabling the test chamber to have a good energy-saving effect on the basis of the same experimental effect (saving about 40% energy)
