PARTICLE COUNTER AND PARTICLE COUNTING DEVICE HAVING PARTICLE COUNTER, AND PARTICLE COUNTING SYSTEM AND ITS USE METHOD

摘要

A particle counting device (11) for detecting/counting particles in a fluid to be measured comprises a measuring section (13) for detecting particles and a control section (12) for processing the output signal from the measuring section (13). If an abnormality occurs, a signal to issuing a warning is generated. With this, always-on monitoring or observation is possible. A particle counting system comprising particle counting devices (11) and an information processing device (17) for processing the results of the counting by the particle processing devices (11) is also provided. The particle counting devices (11) are electrically connected to the information processing device (17) in series and parallel. Alternatively, a particle counting system comprising particle counting devices (11) for detecting/counting particles in a fluid to be measured is also provided. To one of the particle counting devices (11), the other particle counting devices (11) are electrically connected in series and parallel. Therefore, a particle counting system the measurement time of which can be shortened while maintaining the accuracy of the measurement results and its use method are provided relatively inexpensively.
