The UNI-T UT337B air particle counter simultaneously measures particles across six channels, from 0.3 μm to 10 μm, as well as temperature, relative humidity and dew point. It features a 3.5-inch color display, a built-in camera and memory for up to 10,000 records. It connects to a smartphone app via WiFi and to a computer via USB-C for data management and export.
It supports cumulative and differential counting and concentration measurements. The rechargeable Li-ion battery has a capacity of 2,600 mAh, providing approximately 5 hours of operating time with a charging time of approximately 4 hours.
