TSI Remote Particle Counter Model 7501 offers the most features and flexibility of any other remote particle counter on the market today. Easy integration with Ethernet (TCP/IP) or serial Modbus, RTU communications. The instrument can be powered by an Ethernet connection (Power over Ethernet) or a local power source, simplifying installation. It can be configured using a local PC or via a web browser.

Features and Benefits

This particle counter also stores up to 3,000 sample records for data redundancy. The instrument simultaneously reports up to four particle sizes and other key information such as laser current, background light level, last calibration date, serial number and manufacturing date for warranty management.
Digital calibration enables consistency when managing a large number of instruments. With the optional temperature/relative humidity sensor, users can eliminate the need for additional sensors, cabling and powering them in monitoring automation systems or building automation systems. The AeroTrak Remote Particle Counter also has built-in alarm outputs, allowing users to alarm locally from the particle counter.
