The CLJ-3506 laser dust particle counter comes standard with dual USB ports, Ethernet ports, and RS485 ports, and can be equipped with high-precision (temperature/humidity) probes to provide you with a complete solution. The instrument adopts a semiconductor laser light source and a large-sized touch LCD screen display. It has small size, light weight, high detection accuracy, simple and clear functional operation, and is controlled by a microcomputer. It can directly store and print sampling and detection results, making it very convenient to test in a clean environment.
