Offering the best in handheld particle counting

Met One HHPC-6 Handheld Airborne Particle Counter simultaneously displays six channels of particle size distribution. The Model HHPC-6 holds 500 samples (2,000 with Option EX) in data memory and records date, time, counts, sample volume, temperature and relative humidity. Data is easily downloaded to a computer or printer using the included RS-232/RS-485 interface cable and utility software. With value-packed features and excellent reliability, it is easy to see why the Model HHPC-6 is a winner among professionals who monitor and verify cleanrooms, test filters, and track down particle source problems. The intelligent design and overall utility of the Model HHPC-6 is invaluable for IAQ investigations, making workplace environments safer and healthier.
