The Custom Temperature & Humidity Chamber (WH-CJ Series, custom build) is the made-to-order configuration of the standard environmental test chamber, delivered when a standard cabinet size, range or access layout cannot fit the specimen. Wanhe engineers size the chamber, select the cooling and heating capacity and add custom fixtures, cable ports, windows, shelves or load conditions, then apply the same −40 ℃ to +150 ℃ / 20%–98% RH climatic performance with programmable control.
It is chosen for large assemblies, pallet-loaded products, in-line aging rooms and unusual specimen geometries — cases where the standard WH-CJ cabinet is too small. The sizing decisions are explained in the environmental chamber selection guide and how to choose a chamber.
Customization Options
- Chamber volume & dimensions — sized to the specimen and batch size.
- Temperature/humidity range — extended ranges and rates where required.
- Access & loading — doors, windows, cable ports, shelves and cart loading.
- Fixtures & monitoring — specimen power, sensors and data acquisition.
- In-line / walk-in — aging rooms and production-integrated layouts.
Standards & Compliance
Custom chambers are configured for the IEC 60068 and GB/T 2423 environmental series, with ISO 16750 for automotive components; see temperature humidity chamber specs and high/low temperature vs damp heat. Build and lead-time details are in custom test-bench lead time; documentation is summarized on certifications.

Frequently Asked Questions
When do I need a custom chamber rather than the standard WH-CJ?
Choose custom when the specimen is too large, needs special loading or access, or requires an in-line/walk-in aging layout; see the selection guide.
Can a custom chamber match the same accuracy?
Yes. The same ±0.5℃ / ±2% RH control and IEC 60068/GB-T 2423 performance are applied, with uniformity verified for the larger volume.
What is the lead time?
Custom builds take longer than standard cabinets; see custom lead time for a realistic schedule.
