For more than 30 years GRIMM aerosol spectrometers are successfully used all over the world and appreciated by thousands of users. The model 11-C combines in its compact and rugged design both reliable opti cal particle detecti on for counti ng and classifying dust particles as well as advanced data communicati on. The allrounder with no limits for all your applicati ons! The 11-C is suitable for conti nuous measurements via power supply or fl exible usage with a batt ery and remote control for real ti me data acquisiti on and data analysis.

MODEL 11-C (CLASSIC)

This confi gurati on puts the 11-C into the worldwide leading positi on of portable aerosol spectrometers for any common applicati on such as parti cle number concentrati on, PM-values or parti cle size distributi on. The best choice for reliable, fl exible and real ti me measurements for indoor air quality, e.g. at workplaces, inside of vehicles or for process analysis.
