These portable particle counters are ideal for use in cleanroom monitoring, facility certification, pharmaceutical and food processing environments, and more. They are easy to configure and operate with a large touch screen interface and stainless steel enclosure. The display allows the user to view six particle sizes simultaneously, and the memory is capable of storing up to 3000 records. The units have analog inputs for optional environmental sensors: air velocity (82013-990), temperature/relative humidity (82013-994), and differential pressure. They also can accommodate a filter scanning probe and feature battery operation and a built-in printer. An audible alarm alerts for high particle counts, low battery, and sensor failure. Each instrument is individually calibrated and certified using equipment whose calibration is traceable to the National Institute of Standards and Technology. Flow Rate: 28.3 L/min.
