Salt Spray / Constant Temperature & Humidity / High Temperature Composite Test Chamber

Product Name

Salt spray / constant temperature & humidity / high temperature composite test chamber

Application

The salt spray / constant temperature & humidity / high temperature composite test chamber is suitable for aerospace products, information and electronic instruments, materials, electrical and electronic products and various electronic components, to test their performance indicators under high/low temperature or damp heat environments. The salt spray function is suitable for salt spray corrosion tests of components, electronic parts, protective layers of metal materials and industrial products.

Chamber Structure

• The outer shell is CNC-machined from SUS304 stainless steel plate, smooth and attractive.
• The inner chamber is imported high-quality SUS316 stainless steel plate.
• Heating combines inner water-jacket heating and air-circulation heating, giving fast heat-up and uniform temperature distribution.
• All salt spray test accessories are corrosion-resistant and high-temperature-resistant.
• The oversized salt water tank has a preheating function, allowing continuous spraying for 72 hours without refilling salt water or saturator water.
• The chamber lid is shared with the salt spray corrosion test chamber.
• The observation window of the composite chamber uses multi-layer hollow tempered glass.
• The test port can be used for test power supply or signal cables.
• Salt spray tests and constant temperature & humidity tests can be performed separately inside the chamber, with a switching function and no mutual interference.
• A liquid immersion tank of appropriate size can be placed inside the chamber.
• The switching time between the high-temperature chamber and the salt spray chamber is about 10 seconds.
• Temperature recovery time is less than 5 minutes.

Control System

• Intelligent PID temperature & humidity controller
• Membrane KEYBOARD keys
• Power-failure memory function: after power restoration the remaining test process can continue
• Temperature control uses P·I·D + S·S·R with same-channel coordinated control, improving the stability and service life of control components and interface
• Touch-type setting, digital and direct display
• The composite chamber features PID auto-tuning, reducing the inconvenience of manual setting
• Warning signals are provided if errors occur during operation or setting
• Power-failure record retention for 5 years
• Temperature sensor: PT100 platinum resistance temperature sensor
• Salt spray mist is automatically exhausted after spraying is completed or when switching to other modes
