Salt Spray Test Chamber.
Controlled salt-fog exposure for assessing corrosion resistance in coatings, components, materials and surface treatments.
Accelerate corrosion to compare long-term durability.
ISOTECH Salt Spray Test Chambers create a fine, consistent salt-laden fog for evaluating coatings, materials and surface treatments under controlled corrosive exposure.
The environment simulates aspects of marine atmosphere, industrial pollution and road salts for quality assurance, materials development and comparative analysis.
The current page references ASTM, DIN, ISO, DEF and MIL-STD requirements. Confirm the exact method, solution, fallout rate, specimen angle, exposure cycle and acceptance criteria during technical review.
Four exposure states. One controlled cycle.
Special CT models add modified and combined-test functions beyond conventional neutral salt-fog exposure.
Salt-fog exposure
Atomised salt solution produces a uniform, continuous corrosive mist over the specimens.
RT +5°C to +50°CCondensation humidity
Controlled condensed-water exposure supports cyclic corrosion methods and combined humidity phases.
RT +5°C to +45°CDrying & ventilation
Heated ventilation creates the drying phase used in multi-stage corrosion exposure cycles.
RT +5°C to +60°CClimate & modified tests
CT configurations support ASTM G85-style modified tests, SO2, climate, fog-condensation and fog-drying routines.
+20°C to +60°C / 20%-95% RH
Built to withstand the environment it creates.
The housing, canopy and sample system are designed around repeated exposure to a highly corrosive internal atmosphere.
Marine-grade housing
The entire housing uses non-corrosive materials such as marine-grade fibreglass for resistance to continuous salt exposure.
Mobile floor-standing format
Floor-standing units use lockable wheels for secure positioning and controlled relocation.
Accessible sample loading
Working height and reach distances support loading and unloading coupon samples into removable slotted racks.
Open test volume
The uncomplicated workspace maximises open area for more coupons while allowing large and bulky specimens.
Clear gabled canopy
A full clear-view gabled canopy supports observation while helping condensate run away from the test samples.
Insulated removable outer body
The removable insulated covering helps the chamber reach its maximum temperature in cooler laboratory environments.
Condition air, atomise solution, control fallout.
A heated saturator tower, separate solution reservoir and panel-mounted regulation create a uniform salt-fog field.
Wrap-around chamber heating
A heater jacket bonded to the exterior of the internal workspace protects the heater from the corrosive chamber atmosphere.
- External jacket avoids direct corrosive exposure
- Supports stable chamber temperature
- Cabinet over-temperature thermostat
- Designed for repeated exposure cycles
Saturator / bubble tower
The heated bubble tower humidifies compressed air before it reaches the salt-fog atomiser.
- Immersion-heater temperature control
- Independent over-temperature protection
- Automatic fill from pressurised water supply
- Manual filler port standard across models
Salt-solution reservoir
A separate reservoir mixes and holds the salt water that will be atomised into the test fog.
- Provided on all published models
- Separated from the exposure workspace
- Supports continuous solution feed
- Accessible for preparation and service
Fallout and pressure control
An adjustable flow meter works with the integrated air-pressure regulator and gauge to maintain consistent salt-fog fallout.
- Panel-mounted flow adjustment
- Integrated pressure regulator
- Visible pressure gauge
- Uniform, continuous specimen exposure
Programme the exposure and record the cycle.
The large-screen programmable controller combines TFT LCD touch and key input with profile graphics, history trends, ramp-and-soak segments, time totalising and cyclic timing.
Profiles and cycles
Multiple programmes and profile segments support ramp, soak and repeatable cyclic operation.
Connected operation
RS-232/485 ports, networking and USB support external hardware and fast downloads.
Recovery and timing
Power-failure recovery, time totalising and cyclic timing support controlled test continuity.
Single-set PID
RE models use microprocessor PID non-programmable control for chamber and saturator-tower temperature.
Protection for operator, chamber and solution system.
Independent shutdown functions address access, temperature, water supply and electrical malfunction.
Six configurations across three control families.
RE models provide non-programmable PID control, LO models add logic programming, and CT models introduce special combined and modified-test capabilities.
| Model | Control family | Temperature range | Test-space range |
|---|---|---|---|
| ITSP-60 RE | Non-programmable | RT +5°C to +60°C | 150 L to 2000 L |
| ITSP-50 RE | Non-programmable | RT +5°C to +50°C | 150 L to 2000 L |
| ITSP-60 LO | Logic programmable | RT +5°C to +60°C | 150 L to 2000 L |
| ITSP-50 LO | Logic programmable | RT +5°C to +50°C | 150 L to 2000 L |
| ITSP-60 CT | Special model | +20°C to +60°C | 150 L to 2000 L |
| ITSP-50 CT | Special model | +20°C to +60°C | 150 L to 2000 L |

Salt spray chamber guidance.
Answers covering the test principle, applications, standards, selection, service, customization and support.
A salt spray or salt-fog chamber creates a controlled salt-laden atmosphere that accelerates corrosion processes on materials and coatings.
It helps automotive, aerospace, marine and other industries compare material durability and corrosion resistance for product-quality and safety decisions.
Typical specimens include metal components, painted surfaces, plated parts, protective coatings and other corrosion-susceptible materials.
Selection should consider the test standard, specimen quantity and size, exposure mode, control type, workspace, solution handling and any modified-test functions.
ISOTECH references ASTM, ISO, DIN, DEF and MIL-STD methods. Confirm the exact configuration and method during technical review.
Yes. ISOTECH publishes maintenance and calibration services intended to support continued chamber accuracy and reliability.
