The DHT® Europe R&D Center has introduced the DHTLH and DHTSLH series test chambers, which, with their compact design, are particularly well-suited for small sample testing requirements in laboratories, universities, and research institutes. Featuring DHSPLCON technology, these chambers significantly extend the lifespan of ultra (extreme) low humidity chambers. The DHTLH and DHTSLH series provide stable high-low temperature and humidity environments for various test samples, including electronics, electrical components, instruments, parts, and materials. They are widely applied in universities, specialized laboratories, and research and development fields with limited space.
