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.

الأسئلة المتكررة
What does “200-Type” mean?
For this product it corresponds to a 2000 mm internal chamber width. The published internal dimensions are 2000 × 1000 × 600 mm, producing an approximate 1200 L working volume.
Is the DR-H304-200 a true cyclic corrosion test chamber?
The published specification confirms continuous and periodic spraying. A true CCT sequence with controlled humidity and drying requires additional systems. Provide the exact cycle so DERUI can confirm the configuration.
Can the same chamber run NSS and CASS?
The published temperature settings support both modes, but solution chemistry, pH, saturator temperature, materials compatibility and cleaning procedures differ. Confirm the final configuration and operating procedure.
Does ASTM B117 specify the test duration?
No. ASTM B117 defines the salt-fog apparatus and operating practice. The relevant coating, product or customer specification establishes duration and acceptance criteria.
Can salt spray hours predict outdoor service life?
Not directly. Salt spray testing is valuable for detecting defects and checking process consistency, but results should not be converted into a universal number of field-service years.
How should the chamber size be selected?
Use the largest specimen, batch quantity, fixture angle and required clearances. Samples must not block fog circulation or allow condensate to drip onto one another.
