Atmospheric temperature and humidity solar radiation measurement system

QTHiAtmospheric temperature and humidity solar radiation measurement system

QTHiAtmospheric temperature and humidity solar radiation measurement systemIt is a high-precision, compact, and robust data logger used for long-term monitoring of air temperature, humidity, and radiation (global or photosynthetically active radiation). Its built-in sensors and glass optical components ensure measurement accuracy and long-term stability. The radiation protection cover and waterproof design make it suitable for various harsh environments. In addition, the device is equipped with excellent Windows ® The software provides rich data processing and analysis functions. Its non-volatile memory can store a large amount of data, has a long battery life, and is easy to replace.
