UT337B can measure the quantity and size distribution of airborne particles in real time, featuring six-channel synchronous detection for precise monitoring of particulate concentrations ranging from 0.3µm to 10.0µm, along with environmental parameters such as temperature, humidity, and dew point, providing comprehensive and diverse data. With a built-in storage capacity of 10,000 records, it supports photo-linked documentation and offers dual-mode Wi-Fi/USB connectivity, enabling one-click generation of ISO/EU and GMP sampling reports. It is the ideal tool for monitoring indoor air quality and cleanliness levels.
The UNI-T UT337B is a professional-grade laser particle counter offering synchronized six-channel detection of airborne particles from 0.3µm to 10.0µm. Engineered for precise environmental monitoring applications, its intuitive 3.5 inch color display provides clear visualization of particle distribution data in real-time. With advanced features including integrated temperature and humidity sensors, WiFi/USB connectivity, built-in camera, and compatibility with industry-standard ISO/EU-GMP classifications, this versatile instrument delivers the reliability needed by environmental engineers, cleanroom technicians, HVAC specialists, and quality control professionals in pharmaceutical, healthcare, electronics manufacturing, and indoor air quality applications.
The UNI-T UT337B delivers exceptional measurement accuracy with its advanced laser scattering technology, providing reliable detection across all six particle size channels. With counting efficiency of ≥50% at 0.3µm and 100% at 0.5µm, it offers laboratory-grade precision in a portable instrument. The high-flow sampling system ensures rapid data collection at 2.83L/min (0.1CFM), making it ideal for real-time environmental monitoring applications where quick assessment is essential. The specialized ISO and GMP measurement modes provide direct compliance evaluation with international standards ISO 14644-1:2015 (Classes ISO 4-9) and EUGMP Annex 1 (Grades A-D), eliminating the need for manual calculations and ensuring consistent classification across different environments. This capability is essential for cleanroom validation, pharmaceutical manufacturing, and other regulated industries where particle monitoring documentation is mandatory.
