50 L High and Low Temperature Test Chamber
A compact programmable chamber for cold, dry-heat and temperature-change testing of electronic components, automotive parts, materials and small assemblies.
Designed Around the Specimen and Profile
Cold and dry heat
Run controlled low- or high-temperature dwells for storage, operation and material-response evaluation.
Chu trình nhiệt độ
Program ramps and dwells while respecting the refrigeration capacity and heat generated by energized samples.
Compact laboratory footprint
The 50 L class suits components and small assemblies without oversizing the conditioned workspace.
Functions Verified From the Original Product HTML
Programmable touchscreen
Colour LCD menu interface with selectable Chinese and English display and real-time operating curves.
Program capacity
Up to 120 groups, 99 segments per group and 999 cycles; each segment is stated up to 999 h 59 min 59 s.
Communication and records
RS-232 or RS-485 interface, computer monitoring/control, real-time storage and Word/Excel document output. The source states that software can monitor up to 30 devices.
Controller protection
Screen lock helps prevent accidental program changes or shutdown, while PID automatic calculation supports stable control.

SUS304 mirror-finish inner chamber, rigid polyurethane foam and superfine glass-wool insulation, silicone door seals and coated carbon-steel or brushed SUS304 exterior.
Standard accessories
Illuminated observation window, two specimen shelves and one stated 50 mm or 100 mm cable port.
Configuration Checklist
| Mẫu | DR-H201-mini-1 |
|---|---|
| Nominal working volume | 50 L; usable internal W × D × H still requires confirmation on the approved drawing. |
| Phạm vi nhiệt độ | Confirm the ordered low/high limits, fluctuation, uniformity and deviation. Do not copy a range from a different-capacity DR-H201 unit. |
| Ramp performance | Specify heating/cooling rate, start/end temperatures, empty/loaded condition and measurement method for this 50 L configuration. |
| Sample heat load | Declare energized dissipation, cable load and duty cycle so refrigeration capacity can be calculated. |
| Bộ điều khiển | 120 groups, 99 segments/group, 999 cycles, bilingual interface, RS-232/RS-485 and computer software as stated in the source. |
| An toàn | Independent temperature-limit alarm, high/low/over-temperature alarms, compressor overheat/overcurrent/overload and fan-overheat protection. |
Publication checkpoint: The model and 50 L nominal volume are confirmed. Model-specific range, ramp rate, precision, power, dimensions, refrigerant and heat-load capacity still require the DR-H201-mini-1 technical sheet.
Test-Method Context
Common references include IEC 60068-2-1 for cold, IEC 60068-2-2 for dry heat and IEC 60068-2-14 for change of temperature. Automotive programs may reference ISO 16750-4, while defense programs define conditions within MIL-STD-810. The chamber must be configured to the exact edition, procedure, specimen and tolerance; a standards name alone is not a compliance guarantee.
