Portable Particle Counters – Model 3905, 3910 & 3920
The smallest 6-channel portable particle counters in the industry with 28.3L/min (3905), 50L/min (3910), 100L/min (3920) sampling flow rate.
One of smallest in the industry
Since it is only 5.5 kg, it can be easily carried anywhere. Small size, you can measure anywhere you choose.
Easy operation with touch panel
A large 6.4-inch touch panel LCD makes it easy to check and operate.
Extensive option connection
By using the Climomaster anemometer probe(6531-2G), you can simultaneously measure the air velocity, temperature, and humidity of clean air.
