BT-2001 laser particle size distribution analyzer is the first test of a set of dry and wet test in one of the high-performance laser particle size analyzer. Dry process like system, including silent air compressor, autosampler, decentralized, controller, test windows, sample collection devices and other components. Through the autosampler sample delivery to the uniform high-pressure air flow, driven by the high pressure air to disperse a continuous jet, test window, the collector, thus completing the test. In wet-like system, including mixer, ultrasonic dispersing device, circulating pump, testing windows and pipes and other components. For dry and wet test test test window can be easily exchanged, the real use of a machine. BT-2001 laser particle size analyzer to test some imported high-precision semiconductor lasers and optical receiver array, a multi-channel data conversion circuit and serial data transmission, with automatic alignment system and a series of advanced technologies and manufacturing processes so that the instrument is accurate and reliable, test speed, repeatability, easy operation, wide field of application and other prominent feature. The instrument is particularly suitable for the size of the test can not wet the industry (such as magnetic materials, pharmaceuticals, cement, etc.) and comprehensive application of research institutions and universities labs. 
 1. Test range: dry: 0.29μm-275μm 
 Wet: 0.1μm-340μm 
 2. Sampling method: dry: air jet 
 Wet: liquid circulation pump-and micro-sample pool. 
 3. Repeatability error: less than 1% (standard sample deviation between the repeated tests D50). 
 4. Test time: 2-3min / times (including the dispersion time).
