Designed Around the Specimen and Profile

Cold and dry heat

Run controlled low- or high-temperature dwells for storage, operation and material-response evaluation.

Sıcaklık döngüsü

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

Model	DR-H201-mini-1
Nominal working volume	50 L; usable internal W × D × H still requires confirmation on the approved drawing.
Sıcaklık aralığı	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.
Kontrolör	120 groups, 99 segments/group, 999 cycles, bilingual interface, RS-232/RS-485 and computer software as stated in the source.
Güvenlik	Independent temperature-limit alarm, high/low/over-temperature alarms, compressor overheat/overcurrent/overload and fan-overheat protection.
