• True volumetric air flow control with 3 atmospheric pressure and temperature sensors

• Sampling flow-rate continuously regulated to the atmospheric temperature and pressure: reduces evaporation artefacts of volatile compounds (mandatory for PM2.5 according to EU regulations)

• Automatic calibration of the real time optical module (OPM) to the reference measurement (ß gauge)
  Flow calibration possible during the measurement

• Built-in reference gauge for calibration: no need for factory re-calibration

• Calibration screen for atmospheric pressure sensors

• Regulated Sampling Tube (RST) compliant with CEN PM10 and US-EPA standard: sample not affected by seasonal or geographical factors and avoids evaporative losses of semi-volatile particles

• Fibreglass tape with 3 years of autonomy of continuous sampling with daily cycles (1200 cycles)

• Low activity C14 sealed flat source with analyzer lifetime duration

• Rugged instrument, not sensitive to vibration, humidity, temperature…

• New: On board web server compatible with any internet browser. ENVEA Connect™ user interface with on-line help for the display, configuration, maintenance, diagnostics or software updating of the analyser, remotely, from any PC, tablet or smartphone.
