125 L Battery Altitude Simulation Test Chamber
Specify a controlled absolute-pressure hold for battery transport testing without paying for an unneeded heating and refrigeration system. The revised DR-D203 has a 500 × 500 × 500 mm workspace, a 5.0–101.3 kPa absolute-pressure range and automatic vacuum control through a 7-inch touchscreen.
What this chamber is—and is not
DR-D203 is a low-pressure altitude simulation chamber for cells, batteries and other specimens whose test plan calls for reduced air pressure. It does not include active heating or refrigeration. For UN 38.3 T.1, the laboratory must maintain and document the required 20 ± 5 °C ambient condition independently; a pressure-capable chamber alone does not certify a test result.

Product quotation, drawings and factory acceptance results govern the delivered unit.
How to specify a UN 38.3 T.1 setup
This equipment supports the low-pressure portion of a test program; it does not itself confer UN 38.3 approval. Confirm the applicable method and reporting criteria with your laboratory.
Standard safety equipment and operating limits
The confirmed standard configuration includes an emergency stop, pressure protection, pressure-reducing valve, automatic end-of-test release and manual venting. A 19 mm tempered-glass window and side-mounted door restraint are also fitted. The vacuum pump has an exhaust outlet. None of these statements establishes a rated capability to contain battery fire, explosion or thermal runaway.
The standard chamber has no confirmed powered-test feedthrough. Keep specimens unpowered during a standard T.1 storage exposure unless a separately engineered configuration and approved procedure explicitly require otherwise. Gas detection, fire interfaces and laboratory exhaust treatment must be evaluated for the specimen and facility; do not assume they are included.

Common selection questions
Does the DR-D203 control temperature?
No. It is a low-pressure-only chamber without active heating or cooling. The laboratory must establish and document the ambient condition required by its test procedure.
Is a 5.0 kPa minimum enough for UN 38.3 T.1?
The specified pressure range includes the T.1 target of 11.6 kPa absolute or less. Whether a particular test is valid also depends on duration, ambient condition, samples, measurements and the adopted method edition.
Can the chamber generate a compliant test report by itself?
No. Its standard pressure-trace export supports evidence collection, while the laboratory remains responsible for calibration, sample identification, observations, electrical measurements and the complete report.
Configure the chamber for your test plan
Send the required standard edition, specimen details, pressure profile, lab ambient conditions and reporting requirements. DERUI can confirm the delivered configuration, shelf capacity, safety scope and factory acceptance points before quotation.
