Simulated Temperature Humidity Controlled Cabinets ,Environmental Test Chamber Floor Type

Simulated Temperature Humidity Controlled Environmental Test Chamber Floor Type


This Simulation Temperature Humidity Controlled Environmental Test Chamber is mainly used for products in accordance with the requirements of the national standard or user-defined requirements, at low temperatures, high temperature, humidity and temperature cycling conditions, physical and other relevant characteristics of the product environmental simulation test, after tested by detecting to judge the performance of the product, it is still able to meet predetermined requirements in order for the product design, improvement, identification and factory inspection use.

Simulated Temperature Humidity Chamber Features:

  • Under same volume have a larger place space and load heat.
  • Using US new PWM refrigerant control technology to achieve low energy-saving operation.
  • To prevent test samples will not dew condensation control conditions.
  • Communication configuration RS232 interface and USB storage download functions.
  • Machines with multiple alert monitor, configure the wireless remote alarm functions.
  • The safest water systems and renewable water loop circulation system.
  • Humidity Effects can reach 15℃ / 5% RH performance, dehumidification speed fast.
  • To prevent static electricity-saving ability to achieve the industry's best performance.

Test area Picture:

Simulated Temperature Humidity Chamer Work principle:

A.. The controlling system for adjusting temperature and humidity evenly controls SSR through PID. It makes the heating and moisture content equal the loss of heating and moisture

B. The dry and wet balls are used for measuring temperature signal by comparing the A/D conversion input controller CPU and RAN, and input to I/O board. The I/O board gives commands and instructions to operate air circulation system and cooling and freezing system, meanwhile, PID controls SSR, or heats or humidifies SSR for operation in order to make the hot and wet content deliver to the test box evenly through air circulation system, and finally achieve the purpose of adjusting the temperature and humidity evenly.
