The HT-9600 Air Particle Counter 3 Channel is a portable particle and air-quality monitoring instrument for measuring particles at 0.3 µm, 2.5 µm and 10 µm channels. It also measures temperature and relative humidity, with a 2.8-inch colour LCD, manual sampling and onboard data storage.

Product Overview

The HT-9600 is a handheld three-channel air particle counter designed for rapid assessment of airborne particulate concentration. It uses a semiconductor laser light source and optoelectronic detection principle to measure particles in three size channels: 0.3 µm, 2.5 µm and 10 µm.

The instrument provides particle concentration in particles/L or µg/m³, together with temperature and humidity measurements. Its compact design, colour LCD and rechargeable/portable operation make it suitable for field measurements and indoor environmental assessments.

It is particularly useful for cleanroom cleanliness checks, air-cleaner performance testing, filter evaluation, indoor air-quality testing and general particulate monitoring.
