PMScan is a compact PM datalogger for mobile measurements, citizen science, research and exploratory field campaigns. It records PM1, PM2.5 and PM10 along a route, activity or measurement period without requiring a fixed monitoring station.

A compact, battery-powered PM datalogger for mobile measurements, comparative studies and temporary field campaigns.

Particle concentrations can change between streets, transport modes, buildings, rooms and short activities. A fixed monitoring station cannot always describe these local and temporary variations.
A portable datalogger adds time and movement context to particle measurements. PMScan records the concentration in the air close to the instrument, helping users compare environments and identify periods that deserve further investigation.
These measurements support comparative and exploratory studies. They do not represent an inhaled dose or replace regulatory occupational exposure assessment.
Observe how particle concentrations change between streets, transport modes, indoor spaces or selected study locations.
Complement stationary measurements with temporary data collected closer to the environments being investigated.
Record transient variations that may not be visible in periodic measurements or long-term averages.
Carry out temporary measurement campaigns without installing a permanent monitoring network.
Mobile particle measurements provide valuable time and location context, but their interpretation must remain consistent with the measurement objective and the sensing method used.
PMScan measures particle concentrations in the air close to the instrument. It does not determine the quantity of particles inhaled or deposited in the respiratory system.
PM1, PM2.5 and PM10 are not equivalent to the inhalable, thoracic and respirable conventions used in occupational hygiene.
Particle composition, density, shape and refractive index can influence the relationship between optical signals and estimated mass concentration.
Hygroscopic particles may grow under humid conditions. Active humidity management helps improve measurement stability, but it does not remove every aerosol-related uncertainty.
Time, location, activity and measurement conditions are needed to interpret variations collected during a mobile campaign.
PMScan measures particle concentration and size-related information. It does not identify the chemical composition or toxicity of the particles detected.
PMScan is therefore best suited to exploratory measurements, comparisons, trend identification and field studies whose protocol reflects these measurement limits.
PMScan combines TERA Sensor’s NextPM sensing technology with battery power, local data storage and wireless communication in a portable instrument designed for field measurements.
Record real-time particulate mass concentrations together with particle information across five size channels.
Carry the instrument along a route or place it temporarily at a selected measurement location.
Store measurements locally and retrieve the recorded data for comparison and subsequent analysis.
Dual-angle optical detection, active airflow, humidity management and an anti-clogging design support stable measurements during field use.
PMScan supports applications where mobility, rapid deployment and time-resolved particle data are more important than a permanent monitoring installation.
Compare particle levels along walking or cycling routes, between transport modes or across selected indoor and outdoor environments.
Collect portable PM data during research campaigns, pilot studies or protocol development before deploying more specialized instrumentation.
Carry out short investigations around entrances, material transfers, maintenance operations or adjacent environments to identify periods requiring closer examination.
PMScan is not intended for ISO cleanroom classification. Use SafyrOPC when ISO 21501-4 particle counting is required.
Perform exploratory measurements around equipment, work areas or temporary operations to identify where a more formal measurement plan may be required.
PMScan helps users follow how particle concentrations change during a route, activity or measurement period. The resulting record can be used to compare conditions and identify intervals that deserve additional investigation.
Collect particle data beyond a fixed station and closer to the microenvironments included in the study.
Compare routes, rooms, transport modes, time periods or operating conditions using the same portable instrument.
Locate short concentration increases within the recorded timeline and relate them to field observations.
Preserve timestamped measurements for visualization, comparison and subsequent scientific analysis.
Use exploratory results to select locations, periods or situations that require more specialized measurement methods.
PMScan provides a ready-to-use solution for portable measurements, while NextPM can be integrated into custom mobile instruments, research equipment and connected measurement systems.
TERA Sensor can support sensor selection, measurement architecture, electronic integration, communication and prototype development. Through TERA Tronics, projects can also be supported through industrialization and series manufacturing.
PMScan records PM1, PM2.5 and PM10 mass concentrations and particle information across five size channels. Measurements are timestamped and can be stored for subsequent visualization and analysis.
No. PMScan measures particle concentrations in the air close to the instrument. Actual inhaled dose depends on breathing rate, instrument position, particle properties and respiratory deposition, which PMScan does not determine.
No. PMScan is intended for exploratory, comparative and time-resolved field measurements. It does not replace regulatory sampling methods, gravimetric analysis or occupational exposure assessments performed according to the applicable regulations and standards.
No. PM fractions and occupational hygiene dust fractions use different sampling conventions. PMScan data should not be interpreted as a direct measurement of inhalable, thoracic or respirable workplace dust.
Yes. Its portable format and data-logging capabilities make it suitable for comparing routes, transport modes and selected indoor or outdoor microenvironments, provided that the study protocol and measurement limits are clearly documented.
PMScan can support exploratory studies, pilot campaigns and comparative field measurements. Researchers should define an appropriate protocol and, where required, evaluate the instrument against the reference method relevant to their study.
No. PMScan is not intended for cleanroom classification. SafyrOPC should be used when ISO 21501-4 particle counting and cleanroom-compatible monitoring are required.
No. PMScan records particle concentration and size-related optical information. Identifying particle composition or confirming a specific source requires additional analytical methods.
Humidity can change the optical response of hygroscopic particles. The NextPM sensing module integrated into PMScan includes active humidity management to improve stability, but aerosol properties must still be considered when interpreting the data.
Yes. PMScan can be carried during a mobile campaign or placed temporarily at a selected location. The installation and protocol should remain consistent with the objective of the study.
