Description
Shanghai HS2.5 Constant Temperature Humidity Environmental Test Chamber 380V
The Shanghai Yuanchang HS2.5 is a large-capacity, floor-standing constant temperature and humidity environmental test chamber designed for extended conditioning and reliability testing of components, assemblies, and finished products. The "HS2.5" designation refers to the 2.5 cubic meter usable interior volume. The chamber is controlled by a SAMSON TEM900 color touchscreen controller for temperature and humidity programming, monitoring, and data logging. Power is 380V three-phase; a Jefferson Electric 112.5 kVA dry-type step-up transformer (208V Delta input to 380V output) is included, making the chamber compatible with standard North American 208V three-phase service.

Applications
Constant temperature and humidity test chambers are standard equipment in environmental stress screening (ESS), accelerated life testing (ALT), and reliability qualification programs across electronics manufacturing, automotive, aerospace, defense, and consumer goods industries. They are used to subject components, PCBs, finished assemblies, and materials to controlled temperature and humidity conditions — simulating real-world climate exposure to assess long-term durability, corrosion susceptibility, moisture ingress, and thermal cycling performance. Large-volume chambers like the HS2.5 (2.5 m³ interior) are suited for testing bulky assemblies, full system units, or high-throughput batches of smaller parts simultaneously. This class of chamber is commonly used in compliance testing to IEC, MIL-STD, JEDEC, and IPC standards. The SAMSON TEM900 touchscreen controller is a programmable profile controller capable of setting multi-step temperature and humidity ramp-and-soak sequences, making it well suited for both steady-state conditioning and cyclic test profiles.
This Shanghai HS2.5 Constant Temperature & Humidity Environmental Test Chamber has been visually inspected and is in used condition. The exterior cabinet is in good shape with normal wear consistent with lab use. The interior stainless steel chamber shows water staining and residue deposits on the floor and door interior — visible in our photos — which is typical of a chamber that has seen humidity cycling service. The door seal gasket appears intact. The SAMSON TEM900 touchscreen controller is present and intact on the front panel. A Jefferson Electric 112.5 kVA dry-type step-up transformer (208V Delta to 380V/220V, Cat. No. 423-7256-369) is included. The chamber has not been powered up or tested at our facility, but it was pulled from a working lab environment where it was previously in use. Please review all photos carefully and contact us with any questions before purchasing.
