HAL-RPC201 (RS485)


The HAL-RPC201 Remote Particle Counter is the key element of an intelligent multipoint remote facility monitoring system. It is useful in measuring particle concentrations in ultra-clean environments by its single particle counting ability and classification of clean facility. The data collection and sampling time interval can be remotely carried out by a remote computer terminal. The system can run 24/7 continuously and remotely monitor the status of the clean facility and give warning of an excess of count limit preset by the user. It is in compliance with international standards (JIS B 9925:1997 and ISO14644-1) and CE certification.
