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.

Features & Benefits
- 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.
Main Applications
- Ambient air quality monitoring
- Indoor dust monitoring

Principal of Operations
The MP101M, based on the beta attenuation measurement technique, determines the particles 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 collision of dust, whose number is proportional to density. Absorption is thus a function of the mass of the irradiated material, independently of its physico-chemical 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.
Combination of both technologies provides simultaneously approved particulate measurement PLUS real-time indication of PM10, PM2.5 and PM1.
