The DY-8001B high-low temperature chamber reproduces sustained heat, deep cold and repeated temperature change inside a controlled laboratory workspace. Six standard volumes from 80 L to 1000 L cover −40 to +150 °C, with optional low limits of −20, −60 or −70 °C. It is specified to GB/T 2423.1 and GB/T 2423.2 for high and low temperature storage, thermal cycling and environmental stress screening of electronic assemblies, battery cells and packs, automotive parts, metals and engineering materials.
Key features: a programmable touchscreen controller with USB and RS485 data logging, hermetic single-stage or cascade refrigeration, a SUS304 stainless steel working chamber, and complete over-temperature, phase-loss, water-shortage and compressor protection.
Applications
Products in storage, transit and service are exposed to heat, cold and sudden temperature shifts. A high-low temperature chamber applies those stresses in the laboratory so that solder joints, seals, plastics, electrolytes and bonded interfaces can be evaluated in days instead of seasons. With an external charge/discharge analyser wired through the Ø50 mm access port, battery samples can also be characterised at defined temperature setpoints.
The B-series is temperature-focused; humidity control is optional and low-humidity configurations are available on request. For combined temperature and humidity testing, see the DY-8001 programmable constant temperature and humidity chamber. Both families share similar volume steps but differ in refrigeration stage and net weight, so the parameter table of the chosen model always governs.

To specify a chamber, provide specimen dimensions, load quantity and heat dissipation, target temperature range, required ramp rate, and the available electrical supply and cooling water. We match one of the six volumes with the −20 / −40 / −60 / −70 °C refrigeration grades, and also build non-standard volumes, explosion-proof enclosures and multi-chamber linked systems. For UV exposure work see the fluorescent UV aging chamber.
