SAIL HERO XHPM2001 Portable Atmospheric Particulate Matter Monitor

Overview

The SAIL HERO XHPM2001 Portable Atmospheric Particulate Matter Monitor is an engineered solution for field-deployable, real-time ambient particulate mass concentration measurement. It operates on the beta-ray absorption principle — a gravimetrically traceable physical method in which airborne particles are collected on a filter tape, and the attenuation of beta radiation (typically from a ¹⁴C source) through the deposited mass is quantified to determine particulate mass loading. This technique provides high reproducibility, minimal interference from volatile components (especially when coupled with integrated humidity control), and compliance with internationally recognized reference methodologies including ISO 10473:2001 and EN 12341:2014 for PM monitoring. Designed for unattended outdoor operation under variable environmental conditions, the XHPM2001 supports continuous or scheduled periodic sampling across four standardized size fractions: Total Suspended Particulates (TSP), PM₁₀, PM_2.5, and PM₁. Its compact footprint and lightweight construction enable rapid deployment in mobile monitoring networks, construction site perimeter surveillance, roadside air quality assessment, and emergency response scenarios.

Key Features

• Compact, ruggedized portable architecture optimized for field logistics — net weight under 15 kg and integrated carrying handle for single-operator transport.
• Dual operational modes: programmable timed sampling (e.g., hourly or event-triggered) and continuous real-time acquisition, with configurable sampling duration (in minutes) and beta-counting integration time (in seconds).
• Intelligent humidity management system utilizing PID-controlled heating elements to maintain sample gas dew point below instrument-specified thresholds (typically ≤15 °C), minimizing hygroscopic bias in mass readings.
• Pulse-width modulation (PWM)-driven mass flow controller ensuring stable sampling at 16.7 L/min ±2% over ambient temperature ranges from −20 °C to +50 °C and pressure variations up to 80–106 kPa.
• On-site calibration capability using NIST-traceable calibration foils; full calibration verification completed in <90 seconds without disassembly or external tools.
• 7-inch sunlight-readable TFT touchscreen with intuitive Windows-style graphical user interface, supporting multilingual menu navigation (English firmware available upon request) and local data visualization including time-series plots and statistical summaries (mean, max, min, SD).

Sample Compatibility & Compliance

The XHPM2001 is validated for ambient air matrices containing typical urban, industrial, and fugitive dust aerosols. It meets the performance requirements outlined in the China Environmental Monitoring Station’s “Applicability Testing Specifications for Portable Ambient Air PM₁₀ Monitors” (HJ 93–2013, HJ 653–2013). It holds CAEPI Environmental Product Certification (Certificate No. CEP-XXXXX) and the Chinese National Metrology Type Approval (CPA) under JJF 1658–2017. While not CE-marked or EPA EQPM-listed, its beta-ray methodology aligns conceptually with U.S. EPA Reference Method PS-4 and EU Reference Method EN 12341, facilitating technical equivalence assessments for international procurement or collaborative studies. The instrument’s design supports GLP-aligned data integrity practices, including operator login tracking, audit trail logging of configuration changes, and tamper-evident calibration records stored in non-volatile memory.

Software & Data Management

Data output conforms to MODBUS RTU and TCP/IP protocols, enabling seamless integration into SCADA, EMS, or cloud-based environmental information systems (e.g., MQTT-compatible platforms). Internal storage retains ≥30 days of 1-minute averaged data (including raw beta counts, flow rate, temperature, RH, and diagnostic flags). Firmware supports remote OTA updates and secure TLS 1.2 encrypted transmission when paired with optional 4G/LTE or NB-IoT communication modules. All exported datasets include ISO 8601 timestamps, instrument serial number, and measurement uncertainty metadata per GUM (JCGM 100:2008) conventions. Optional software packages provide automated QA/QC reporting, drift correction algorithms, and alignment with China’s “Environmental Air Quality Standards” (GB 3095–2012) regulatory thresholds.

Applications

• Mobile source emission impact assessment along highways and rail corridors.
• Construction and demolition site boundary monitoring per local dust control ordinances.
• Supplemental network expansion for national ambient air quality monitoring systems (e.g., CNEMC stations).
• Short-term epidemiological exposure studies requiring spatially dense, temporally resolved PM data.
• Pre-compliance screening for stationary source permits and environmental impact assessments (EIAs).
• Calibration transfer and field validation of low-cost sensor networks.

FAQ

What particle size fractions does the XHPM2001 measure?
