Constant temperature and humidity (climatic) chambers are the workhorse of environmental simulation testing under GB/T 2423 and IEC 60068-2. The most common question from buyers: which volume and temperature range do I need?

• 150L — benchtop-scale testing of small electronic components, PCBs, connectors. Lowest operating cost.
• 225L — the most versatile size; fits whole sub-assemblies, small appliances, automotive parts.
• 800L — full device-level testing, complete telecom racks, batch testing of multiple samples.

Temperature range: standard -40°C to +150°C covers most electronics applications; -70°C versions serve automotive and aerospace requirements. Humidity range 20%-98% RH with typical control accuracy ±0.5°C / ±2%RH.

Dongyang Machinery manufactures programmable chambers in 150L/225L/800L and custom volumes, with touchscreen controllers, multi-segment programmable curves, USB data export and remote monitoring.
