250L to 1000L cabinets for batch-scale temperature humidity testing
Floor-Standing Environmental Chambers
A floor-standing environmental chamber is what a temperature humidity study looks like at batch scale: whole production runs conditioned at once, complete shelf-maps of test panels, pallet-level packaging trials. The RHS-F series runs 250L, 400L, 500L, 800L and 1000L cabinets on one controller platform — the same 7-inch touchscreen programmer as the benchtop units, with RS485 added for central monitoring. Large capacity changes the engineering problem: the refrigeration and humidification circuits must recover setpoint after a full door opening, hold uniformity across a loaded — not empty — cabinet, and do it for the weeks a steady-state study lasts. WSHLab qualifies each RHS-F model at the envelope corners with a representative load, and the factory test report shows the uniformity map, not just the setpoint. Sizes match real workloads: 250L and 400L for QC and pilot batches, 500L and 800L for production conditioning, 1000L for full stability-scale load or industrial panels. Tell us the sample dimensions and the throughput and we will quote the cabinet that fits both.

TECHNICAL DATA
Engineering the RHS-F floor-standing series
The RHS-F platform scales the balanced refrigeration and ultrasonic humidification circuit to cabinet volume: a bigger compressor pair, dual-wall insulation sized for steady-state efficiency, and an airflow pattern that holds ±0.5°C / ±3% RH across a fully loaded cabinet. The door carries a double-layer tempered glass window and a magnetic gasket; RS485 feeds central monitoring while USB remains the export path.

Applications
Where floor-standing chambers work
Batch-scale temperature humidity testing across pharmaceutical, electronics, materials and packaging labs.
Damp heat testing — 40°C/93%RH steady states for electronics, components and assemblies
Packaging validation — pallet and carton-scale humidity exposure with label adhesion checks
Materials conditioning — textiles, adhesives and plastics at standard atmospheres
Thermal cycling — programmable excursions for fatigue and stress screening at scale
Long-duration steady states — weeks-long programmes with logged proof
PERFORMANCE & SELECTION
What is a floor-standing environmental chamber?
A floor-standing environmental chamber is a temperature and humidity controlled cabinet sized for the laboratory floor rather than the bench. In the WSHLab RHS-F series that means 250L to 1000L of working volume behind one insulated door, with the 7-inch touchscreen programmer, 304 stainless chamber, ultrasonic humidification and USB/RS485 export of the full platform.
- 250L, 400L, 500L, 800L and 1000L working volumes
- 0–60°C and 40–95% RH — the full temperature humidity envelope
- RS485 remote monitoring alongside USB export
- Adjustable shelves sized for batch and panel loads
CONFIGURATION & COMPATIBILITY
Large capacity options
Capacity is not one number: it is the shelf layout multiplied by the airflow. A 250L cabinet fits a QC batch; a 1000L cabinet holds a production conditioning run or a complete packaging trial. Between them, 400L, 500L and 800L sizes let a laboratory match the cabinet to the workload without paying for empty volume or squeezing the load. All five sizes share the same controller and documentation.
- Five capacities, one controller platform, one spare-parts list
- Adjustable stainless shelves — reconfigure between studies
- Door-in-door viewing window for load checks without breaking the climate
- Full-load uniformity verified at the factory, not estimated
