  • Sweedon’s policy of continual liaison with leading researchers ensures high quality supply of environmental chambers and associated facilities .

  • High quality components , design, expertise enables to offer outstanding control performance of the integrity of results of temperature humidity, atmospheric testing.

De humidification system: 

A refrigeration based de humidification system provided to avoid the condensation forming on test specimen as well as control the lower relative humidity.

The desired level of lower humidity will be achieved by maintaining the precise dew point temperature.

The output will be automatically activated based on the set points as well as in ramp up mode after a low temperature cycle.

Refrigeration System :

  • A High boosted low temperature application sealed/ semi sealed compressor is used to Achieve and maintain the required  negative temperatures .

  • Non CFC eco friendly refrigerants are used with components complying to all international safety and environmental guidelines.

  • The system is provided with adequate safety protection against excessive and low pressure and high pressure.

  • Pressure gauges provided to indicate suction and head pressure .HP/LP cut off switch and overload protection for the system.

  • Oil separators with oil return & hot gas defrost provided

Water mist humidification system:

  • A fine mist spray/fog from the atomizer can be adjusted as per required amount of fog inside the chamber.

  • This system will work through the water solenoid valve & it controls from the programmer.

  • Independent air pressure line will be connected to the atomizer to vacuum the water from reservoir tank.

  • The atomizer designed such a way that avoids of direct droplets & it is called as micro condensation system.

Light system &intensity:

The light level is 2000 lux to 10000 lux


  • The Hygro clip series are digital humidity-temperature probes based on the air chip 3000 technology or 4 -20 mA. These probes feature a UART serial interface and two 0…1 V linear analog output signals.

  • The probes are designed to use with the hygroclip 2 generation of ROTRONIC humidity temperature instruments.

  • The probes maintain all of the benefits of the original hygroclip technology such as the possibility of hot swapping probes and features significant improvements in the area of measurement accuracy and functionality
