Aerosol Electrometer

Aerosol electrometers detect airborne particles that carry an electrical charge. Quantifying charged particles requires highlight sensitive measurements based on a Faraday cup.

TSI aerosol electrometers build on Faraday’s discovery to enable precise readings. Their calibration is traceable to standard SI units, making them ideal as reference instruments. Researchers can create a particle number concentration reference standard by combining an electrometer with a particle size classifier (3940).
