PURPOSE: To continuously measure and data-process the temperature and humidity in a tunnel over a long period.
CONSTITUTION: Measurement analog signals from temperature sensors and humidity sensors of temperature and humidity detectors arranged at multiple measurement positions in a tunnel are converted into digital signals via a converting unit 6, the digital signals are inputted to a data logger 7, and the measured values at the measurement positions are recorded on a memory card 10 at every preset fixed period. The memory card 10 is recovered and read out by a memory card driver 16, the output is fed to a personal computer 17, and listing and statistical processes are performed in a temperature/humidity measurement section P and a data analysis section Q by means of the software 23 analyzed in advance.
