DR-H304-200 1200 L Programmable Salt Spray Chamber
A wide 2000 mm test workspace for continuous or periodic salt-fog exposure of large panels, coated assemblies, fasteners and production batches. The DR-H304-200 supports NSS/AASS and CASS operating conditions when configured and operated according to the applicable test method.
2000 × 1000 × 600 mm workspace
Approx. 1200 L
Continuous / periodic spray
Designed for Large Specimens and Batch Corrosion Tests
The “200-Type” identifies the 2000 mm internal width—not a 200 L benchtop unit. Its broad test space accommodates long coating panels, multiple racks of components and larger fabricated parts while preserving clearance for fog circulation and collection.
Large Working Area
A 2000 × 1000 × 600 mm chamber provides room for production batches and long specimens that do not fit conventional 90- or 160-type cabinets.
Programmable Spray Timing
Run continuous fog or timed spray/stop periods according to the selected laboratory procedure and product specification.
NSS, AASS and CASS Conditions
Published temperature and pH settings support neutral, acetic-acid and copper-accelerated acetic-acid salt-spray methods when the required solution and configuration are used.
Cyclic terminology: periodic spray/stop control is not automatically the same as a full cyclic corrosion test (CCT). A sequence such as salt fog, controlled humidity, dry-off and ambient dwell requires dedicated humidity, air-drying and transition hardware. Confirm those modules before claiming compliance with an automotive CCT specification.

Test Preparation and Verification Workflow
Define the Method
Confirm the standard edition, solution chemistry, pH, exposure mode, duration, specimen orientation and acceptance criteria.
Condition the Cabinet
Prepare the prescribed water and salt solution, stabilize temperatures and verify fog collection before loading qualification specimens.
Control the Exposure
Record temperature, collection rate, pH, interruptions and replenishment events without unnecessary lid opening.
Specimen Loading
- Use corrosion-resistant supports
- Maintain the specified orientation
- Prevent specimens from shielding one another
- Prevent condensate from dripping between samples
- Leave space for uniform fog circulation
Routine Checks
- Fog collection and distribution
- Chamber and saturator temperatures
- Solution concentration and pH
- Nozzle condition and air quality
- Tank, seals, drains and alarms
