UNI-T UT337B 6-Channel Laser Particle Counter

UNI-T UT337B 6-Channel Laser Particle Counter in Sri Lanka

Portable Airborne Particle Measurement for Cleanrooms and Indoor Environments

The UNI-T UT337B 6-Channel Laser Particle Counter is a professional handheld instrument for measuring the quantity and size distribution of airborne particles in real time. It simultaneously detects particles in six size channels from 0.3 μm to 10.0 μm, making it suitable for cleanroom monitoring, laboratory inspections, operating-room checks, indoor air-quality investigations, and manufacturing cleanliness assessments.

With a 0.1 CFM sampling flow, cumulative and differential counting modes, programmable sampling times, built-in temperature and humidity measurement, and storage for up to 10,000 records, the UT337B helps quality-control and maintenance teams document particle conditions efficiently. Its Wi-Fi and USB connectivity also support data transfer and the preparation of PDF and CSV reports.
