Automatic & Real-Time Suspended Particulate Monitor

MP101M + OPM

MP101M Beta gauge monitor with its optional OPM (Optical Particulate Monitor)

The standard Beta gauge measurement Method ISO 10473 of the MP101M analyzer allows, when used with the optical technology of the OPM module, the continuous and simultaneous measurement of fine dust.
The beta attenuation instrument is compliant with EN 16450 for PM10 and PM2.5 European Standards. QAL1 certified by the TÜV, the MP101M is also approved as Federal Equivalent Method (FEM) by US EPA for PM10 and PM2.5 continuous suspended particulate monitoring.

  • Precise beta attenuation monitoring of PM10, PM2.5, PM1
  • Real time optical indication about PM10, PM2.5, PM1 mass concentration (μg/m3) using an independent inlet

PRINCIPLE OF OPERATION

The MP101M, based on the beta attenuation measurement technique, determines the particle concentration by measuring the amount of radiation that a sample, collected on a fiber tape, absorbs when exposed to a radioactive source.
Low-energy beta rays are absorbed by the collision of dust, whose number is proportional to density. Absorption is thus a function of the mass of the irradiated material, independently of its physicochemical nature. The OPM’s (Optical Particulate Monitor) principle is based on the measurement of the light scattered by the particles. A powerful algorithm is applied to continuously convert the signal into mass concentration.
The combination of both technologies provides simultaneously approved particulate measurement PLUS real-time indication of PM10, PM2.5, and PM1.

 

FEATURES AND BENEFITS

  • True volumetric airflow control with 3 atmospheric pressure and temperature sensors
  • Sampling flow rate continuously regulated to the atmospheric temperature and pressure: reduces evaporation artifacts 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 is 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
  • Fiberglass 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: Onboard web server compatible with any internet browser. ENVEA Connect™ user interfaces with online help for the display, configuration, maintenance, diagnostics, or software updating of the analyser, remotely, from any PC, tablet, or smartphone.
  • Ambient air quality monitoring
  • Indoor dust monitoring
  • Working places
