TH-G Control accuracy
Environmental Chamber

The graphs above illustrate the stable Temperature and Humidity Control Range for the TH-G Series chambers. The yellow areas represent the optimal operating zones where both temperature and humidity can be maintained. However, continuous operation below 30 °C for more than 24 hours is not recommended, as indicated by the hatched areas. 

Performance

This chamber features microprocessor PID control for precise temperature calibration and automatic tuning. Its advanced capabilities in low and high-temperature management, coupled with effective humidity control, make it ideal for long-term testing. The humidification tank is strategically placed to enhance performance while reducing water consumption through an efficient recycling and filtering system.

An air-tight door closure ensures that heat loss is minimized, thanks to heat-resistant silicone packing that effectively blocks high temperatures. A two-point door latch further enhances the tightness of the closure, contributing to energy efficiency through optimized insulation. Even at maximum temperature settings, the unit remains safe to touch, with surface temperatures not exceeding 60℃.

 

Safety Features

Safety is paramount in laboratory settings. This chamber includes:

  • A built-in door lock with a key for security.
  • Automatic shut-off activated by an overheat alarm.
  • Low and empty water level alarms for operational integrity.
  • A power supply leakage breaker and overcurrent protection.
  • An open-door alarm to prevent unintended exposure.

 

Convenience

With a spacious chamber volume of up to 1500L, it caters to various user needs. The corrosion-resistant stainless-steel construction and electric polished humidification tank ensure durability. Maintenance is straightforward, facilitated by a front water tank and a portable water container for easy refilling. Optional direct water systems enhance convenience for long-term tests.

The tempered glass door with built-in heating wire allows for clear observation of your samples. Energy-efficient LED lighting boosts visibility, while optional inner glass doors provide a wider view. A 50mm diameter cable port is standard for connecting external probes, with customizable options available.

Mobility is also a focus, with casters for easy relocation. Our user-friendly LCD controller features a 5.7-inch interactive touch display, allowing you to monitor set and present values simultaneously. Operating progress is easily interpretable through graphical modes, and built-in SD card support allows for data recording.
