PROBLEM TO BE SOLVED: To provide a portable type environment measuring system superior in utilization, capable of maintaining obtained environment data, even if the measurement is interrupted and, of easily discriminating whether the environment data are the data when the measurement was interrupted. SOLUTION: Sensors 4a to 4d, measuring at least one of the physical quantities and chemical quantities in the environment and outputting as environment data, are provided. A first memory domain for recording mark signal for determining whether the measurement is stopped is provided. A second domain region for storing the measured environment data and outputting is provided. A controller 3 for controlling the sensors, the operation of the first memory domain and the second memory domain is provided. The controller 3 controls the first memory domain so as to contain the mark signal in the first memory domain, when the environment data after initiation of measurement are stored in the second memory domain, and to delete the mark data, when the measurement is terminated.
