Description
The Met One DR-528 Handheld Particle Counter is a portable and high-precision instrument designed for real-time particle monitoring across a wide range of applications, including cleanroom inspections, HVAC system assessments, and indoor air quality studies. It measures particle sizes from 0.3 µm to 25 µm across eight calibrated channels, with a concentration range of up to 3,000,000 particles per cubic foot (105,900 particles/L). Using a 90 mW, 780 nm laser diode, it delivers accurate and reliable particle counts with ±10% accuracy relative to calibration aerosol. A 2.8″ full-color TFT display ensures clear, easy-to-read readings, while the lightweight design and compact dimensions make it highly portable for field use.
The DR-528 is built for intuitive operation and enhanced user control, featuring 10 user-identifiable alphanumeric location IDs, a menu-driven multi-function rotary scroll wheel, and an easy-to-navigate interface. Additional features include a numeric sample countdown timer and a concurrent tools menu to expand device functionality. Powered by a 7.4 V, 2,200 mAh Li-ion battery with AC charging capability, it offers reliable operation in environments ranging from 0°C to 50°C, making the DR-528 a versatile, efficient, and user-friendly solution for accurate particle monitoring and air quality management.
