The DHT® Temperature & Humidity Calibration Chamber is engineered for the precise calibration and verification of environmental sensors, serving meteorology, environmental monitoring, research laboratories, and quality assurance sectors. It delivers a stable, controllable environment to ensure the accuracy and reliability of tested instruments. Equipped with advanced control systems, it offers high-precision temperature and humidity regulation tailored to diverse sensor calibration needs.
Ultra-Precise Control: Advanced PID algorithms ensure ±0.2°C temperature stability and ±1.5%RH humidity accuracy.
Broad Operational Range:The temperature control range is from -70°C to 180°C, and the humidity control range is from 10% to 98%, making it suitable for the calibration of various types of temperature and humidity sensors.
Rapid Thermal Cycling: Achieves heating/cooling rates of 3°C/min, reducing calibration time by 30%.
Dynamic Environment Simulation: Replicates extreme climatic conditions (e.g., tropical humidity, arctic cold) to validate sensor resilience.
Safety Assurance: Multi-layered protections, including over-temperature/over-humidity alarms and emergency shutdown protocols.
