Charme® — Portable Aerosol Electrometer
Charme® — Portable aerosol electrometer (chargemeter) for the measurement of aerosol concentrations in the range of 2 nm up to 100 µm
Description
The Charme® electrometer works by capturing all the particulate sampled and measuring the total charge as current produced as the charge drains to earth.
By using replaceable gravimetric filters a correlation of the measured electric charge (particle charge) to the mass concentration can be determined for high aerosol concentrations.
The Charme® has been compared with established electrometers held at the Federal Office of Metrology METAS (Switzerland) and achieved very good measurement results.
The Charme® mobile aerosol electrometer operates both on mains power and its internal battery, with a touch screen display. It displays particle concentration and electrometric flow graphically.
Sampling flowrate is 1 - 8 l/min with a measuring range of 1fA - 22500fA for particles from 2nm — 100µm (the upper diameter limit is determined mainly by aerosol transport losses through the sampling line).
Applications
- Environmental measurements
- Workplace measurements
- CPC calibration
Particular advantages
- Real-time, continuous particle concentration measurement. At the same time a removable gravimetric filter can be used to determine mass concentration
- Portable with support of battery operation
- Integrated computer with 3.5” touch panel display
- Intuitive user interface with sophisticated software for data evaluation
- Supports network connectivity
- Integrated interface for process control applications
- Measurement range 1 fA — 22,500 fA, volume flow 1 — 8 l/min
