Particle counter without display SP2-XR

Product overview
The SP2‑XR provides accurate, size‑resolved single‑particle measurements of black carbon mass and particle size with real‑time direct output suitable for monitoring, field campaigns and airborne research.

Features and benefits

• Real‑time data — Continuous, per‑particle output of black carbon mass and size for direct integration with environmental monitoring datasets.
• Single particle detection — Resolves particle‑to‑particle variability to improve source attribution and model inputs.
• Smart data analysis — Streamlined output of measured and derived parameters for rapid interpretation and post‑processing.
• 50 nm particle detection — Incandescent detection down to ~50 nm for particles relevant to primary pollution and health studies.
• Space‑saving design — Compact, lightweight package suited to field deployment and installation on research aircraft.
• Simplified maintenance — Designed for straightforward calibration, alignment and cleaning to minimize downtime.
• Lifecycle Care Program — Optional support offering to maintain instrument integrity and performance over a defined service period.

Technology

• Laser incandescence and particle light‑scattering measurement principles.
• High optical‑power intracavity Nd:YAG laser (1064 nm) heats light‑absorbing particles to incandescence; incandescent signal is correlated to black carbon mass.
• Single‑particle light scattering is measured to indicate particle size, non‑BC aerosol number and mass concentrations.

Main applications

• Climate modelling and radiative forcing studies
• Human health and exposure research
• Pollution characterization and source apportionment
• Measurement of soot in snow, ice or water and calibration of other black carbon instruments (e.g., Aethalometer)

Software and toolkit
The SP2‑XR graphical user interface delivers intuitive, real‑time output of measured and derived parameters (black carbon mass and particle size). The SP2‑XR toolkit processes calibration datasets to generate threshold tables for real‑time conversion of signals to black carbon mass and particle size.

Accessories

• Nebulizer for liquid samples with optional autosampler
• Aircraft aerosol inlet
• Zero count filter
