DR-H201-150L Humidity Heat Test Chamber
Apply programmed temperature, steady damp heat and cyclic humidity profiles to electronic modules, automotive components, materials and assemblies in a 150 L workspace. Select the temperature option and refrigeration capacity from the complete specimen load, powered heat and required climatic profile.
Where the 150L Chamber Fits
The 150 L configuration offers more fixture and specimen capacity than a compact 80 L unit while remaining a floor-standing laboratory chamber. It is suited to medium-sized component loads when the occupied workspace still permits conditioned air to circulate.
Electronic assemblies
Condition PCBs, connectors, control modules and sensor assemblies under defined temperature and moisture profiles.

Evaluate housings, electronics, seals and material interfaces using the applicable customer or industry procedure.
Materials and research
Run controlled conditioning, damp-heat exposure and comparative ageing studies with documented specimen placement.

How the Climatic Control System Works
Control air temperature
Heating and refrigeration establish the programmed chamber-air temperature and transition rate.
Regulate moisture
Humidification and dehumidification control relative humidity within the valid combined operating envelope.
Distribute and record
Forced circulation and calibrated sensors determine how the condition is distributed and documented through the usable workspace.

Loading and Operating Discipline
Maintain airflow clearance
Confirm fixture and specimen placement without blocking supply or return air. Nominal volume is not the same as usable loaded space.
Seal cable entries
Close unused cable-port area to limit ambient air and moisture leakage that can disturb control or encourage frosting.
Confirm water requirements
Follow the approved manual for water quality, tank or direct-feed arrangement, drainage and routine humidifier maintenance.
Define dwell start
State whether exposure time begins at controller setpoint or after specimen sensors reach stabilization.
Record the loaded state
Document mass, location, fixture, powered operation and interfaces so later cycles can reproduce the same condition.
Manage condensation
Select a procedure-appropriate ramp and post-test handling sequence when surface moisture could influence results.
Map the Chamber to the Test Procedure
Use the standard and product specification to define the profile. The chamber supports environmental exposure only when its selected configuration covers every required setpoint, transition and tolerance.
| Reference | الاستخدام النموذجي | Confirm before testing |
|---|---|---|
| IEC 60068-2-30 | Cyclic damp heat | Edition, cycle, transitions, condensation and recovery |
| IEC 60068-2-78 | Steady-state damp heat | Temperature, RH, duration, stabilization and evaluation |
| MIL-STD-810H Method 507.6 | Tailored humidity exposure | Procedure, climatic cycle, specimen operation and acceptance criteria |
| JESD22-A101 / A100 | Electronic-device moisture testing | Applicable method, bias interfaces, safety and monitoring |
Choose 150L Only When the Load Fits
80L chamber
Better suited to smaller loads when footprint and lower conditioned volume are priorities.
150L chamber
Provides a published 500 × 500 × 600 mm workspace for medium-sized component and fixture layouts.
408L or larger
Review a larger cabinet when the complete loaded envelope or required airflow clearance cannot fit the 150 L workspace.

الأسئلة المتكررة
What are the published 150L internal dimensions?
The current table lists 500 × 500 × 600 mm. Confirm the width, depth and height order on the approved drawing before checking specimen fit.
Does 20% to 98% RH apply at every temperature?
No rectangular envelope should be assumed. Request the combined temperature-RH operating chart for the selected configuration.
How much powered heat can the standard chamber handle?
The visible technical table does not publish a confirmed watt limit. Provide maximum specimen heat so DERUI can size the refrigeration system and state loaded performance.
Will it run on 220V single-phase power?
The current visible table does not confirm supply for this specific configuration. Voltage, phase, current and rated power must be included in the quotation.
What water system is standard?
The visible page does not establish a confirmed tank volume or direct-feed arrangement. Confirm water quality, storage/feed method and drainage in the bill of materials.
What should be sent for a quotation?
Send the standard, specimen drawing and mass, powered heat, full climatic profile, interfaces, utilities and FAT requirements.
Configure the 150L Chamber from the Loaded Test
Send the complete profile and specimen information. DERUI can confirm the low-temperature option, humidity envelope, refrigeration capacity, interfaces, utilities and acceptance plan before quotation.
