Standard Temperature & Humidity Test Chamber
Environmental simulation chamber for testing materials by simulating conditions at desired temperature and humidity levels
Ideal for environments where precision matters, our standard temperature and humidity test chambers help calibrate a wide range of temperature and humidity instruments. They work equally well for routine verification of standard thermohygrometers and for fine-tuning high-accuracy sensors, transmitters, data loggers, and inspection devices. Acting as a reliable alternative to conventional humidity generators, these environmental test chambers combine stability and flexibility to meet the calibration needs of labs, quality control departments, and production lines.
Features
- Uses dew point temperature control technology to achieve humidity levels below 5% RH, providing stable and precise conditions for calibration.
- Performance specifications exceed the requirements set by standards such as JJG205, JJF1076, and JJF1564, ensuring high measurement reliability and compliance.
Our temperature and humidity test chamber models comply with the following standards:
- EN IEC 61000-6-2:2019
- EN IEC 61000-6-4:2019
- EN 61010-1:2010+A1:2019

Optional upgrades are available to extend the working range, covering humidity from 5% to 95% RH and temperatures between 20 °C and 95 °C.
Can the dew point be adjusted continuously across the working range?
Can the dew point be adjusted continuously across the working range?
Yes. The chamber uses intelligent refrigeration that smoothly regulates cooling capacity. This makes it possible to set and maintain the dew point precisely across the entire range, which is essential for accurate calibration.
What control technology keeps temperature fluctuation as low as ±0.05 °C?
What control technology keeps temperature fluctuation as low as ±0.05 °C?
An optimized dual-direction PID control system constantly fine-tunes the thermal response. Within the 15 °C to 30 °C range, it can even maintain fluctuations below ±0.02 °C, supporting applications that require exceptional temperature stability.
Humidity control is usually difficult to keep within tight limits. How does this standard temperature test chamber achieve ±0.15% RH?
Humidity control is usually difficult to keep within tight limits. How does this standard temperature test chamber achieve ±0.15% RH?
Maintaining consistent humidity is indeed more challenging than controlling temperature. Our standard temperature and humidity test chamber applies an innovative dynamic humidification balancing method that continuously corrects variations, helping achieve remarkably stable humidity levels during testing and calibration.
