TVOC MONITOR BY PASSIVE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a TVOC monitor by a passive method capable of continuously storing instantaneous values of the concentration of TVOC in atmospheric air and/or average values at any given time.;SOLUTION: The TVOC monitor comprises a sensor part 1 provided with at least a TVOC sensor and a temperature sensor, a microprocessor having an interface, a memory part provided with at least a memory means, and a main body part 3 provided with an electric power supply part. The sensor part 1 continuously detects the concentration of TVOC and transmits it to the main body part 3, a separate body from the sensor part 1, via a communication means 2. The main body part 3 computes reception data at the microprocessor, computes instantaneous values of the concentration of TVOC and/or average values at any given time, and stores acquired data in the memory means, The sensor part 1 can be mounted on an object to be monitored. An alarm issuing part 7 can be included.;COPYRIGHT: (C)2004,JPO&NCIPI
