The Temperature and Humidity Calibration Chamber for Thermometers and Hygrometers features a compact benchtop structure with working volumes typically ranging from 50 L to 100 L, making it ideal for laboratories where space is limited but accuracy demands are high. Despite its small footprint, the chamber provides full-scale environmental simulation performance with uniform airflow distribution and minimal spatial deviation. The noise level is controlled at ≤65 dBA, allowing quiet operation in shared laboratory environments without affecting precision measurements or operator focus. The interior is constructed from SUS304 stainless steel, ensuring corrosion resistance, easy cleaning, and long-term durability under frequent humidity cycling conditions.
Advantages of LIB Temperature and Humidity Calibration Chamber
1. High-Precision Calibration Performance: Equipped with PT100 Class A sensors (0.001 °C resolution), the chamber ensures temperature stability within ±0.3 °C and humidity accuracy within ±2 % RH. This level of precision is essential for reliable instrument calibration.
2. Compact Benchtop Design: With a small footprint of approximately 0.9 m², the chamber can be placed directly on laboratory benches or workstations, making it ideal for space-limited calibration labs.
3. Wide Environmental Simulation Range: The system supports –40 °C to +100 °C and 20 % to 98 % RH, allowing full-range calibration of sensors used in industrial, medical, and environmental monitoring applications.
4. Excellent Environmental Uniformity: Optimized airflow circulation ensures consistent temperature and humidity distribution throughout the chamber, eliminating measurement deviation caused by uneven exposure.
5. Automated Calibration Programs: The 7-inch touchscreen controller supports up to 120 programs with multi-step calibration sequences, enabling unattended operation and improving testing efficiency.
6. Stable and Durable Structure: SUS304 stainless steel interior and reinforced outer casing ensure long service life and resistance to moisture, corrosion, and chemical exposure.

Typical Calibration Applications
The Temperature and Humidity Calibration Chamber is widely used for calibration and verification of environmental instruments in different industries. Common applications include calibration of digital thermometers used in cold chain logistics, humidity sensors used in storage warehouses, environmental monitoring devices in cleanrooms, and system sensors used in building management systems. A typical calibration process may include maintaining 25 °C / 50 % RH for baseline verification, followed by 40 °C / 85 % RH for high-humidity response testing, and 0 °C for low-temperature accuracy confirmation. These controlled cycles ensure that instruments maintain accuracy across their full operating range.
