Particulate Air Sampler for Rapid Emergency Deployment

Product Introduction

When environmental emergencies strike — industrial dust releases, wildfire smoke events, construction dust complaints, or chemical spill incidents — response teams need monitoring equipment that deploys in minutes, not hours. The HM-H4 particulate air sampler from HM Instruments is purpose-built for exactly these scenarios. By eliminating gaseous sampling channels entirely, the instrument achieves a streamlined setup that gets operators collecting TSP, PM10, and PM2.5 samples faster than any multi-channel alternative. At just 4.0 kg with compact 165×330×275 mm dimensions, it fits easily into emergency response vehicles and can be hand-carried to remote or difficult-to-access monitoring sites.

The HM-H4 delivers a particulate sampling flow range of 10–130 L/min with accuracy better than ±2.5%, ensuring that even in the urgency of emergency deployment, the collected data meets professional-grade quality standards. Flow stability better than ±2.0% guarantees consistent sample volume throughout the entire monitoring period, while the automatic pre-gauge pressure and atmospheric pressure measurement system calculates standard-condition volumes in real time — essential for comparing results across different deployment sites and altitudes. The sampling timer, accurate to better than ±0.2%, supports flexible time-weighted average (TWA) assessments ranging from 1-minute spot checks to 99-hour extended campaigns.

Perhaps most critically for emergency operations, the HM-H4 features robust power failure data protection. When field power supply is interrupted — a common occurrence at incident sites — all sampling data is automatically preserved and sampling resumes without data loss once power is restored. The dual power supply design accepts AC220V±10% 50Hz mains or DC29.4V/5A external battery, providing operational flexibility where grid power may be unreliable or unavailable. At $600, the HM-H4 enables response organizations to equip multiple teams with dedicated particulate monitoring capability without exceeding budget constraints, ensuring broader coverage during large-scale incidents.

Applications

• Emergency pollution incidents — Rapid TSP/PM10/PM2.5 assessment during industrial dust releases, chemical spills, and environmental accidents requiring immediate on-site data
• Wildfire smoke monitoring — Particulate level surveillance near wildfire-affected communities for public health protection and evacuation decision support
• Construction dust compliance — Rapid deployment at complaint-driven construction sites for regulatory dust level verification
• Industrial hygiene response — Workplace particulate exposure assessment during process upsets, maintenance events, or accident investigations
• Military and defense field monitoring — Portable particulate sampling at forward operating bases, training ranges, and deployment sites
• Community air quality events — Resident-requested monitoring during suspected air quality deterioration in residential areas
• Disaster response operations — Post-disaster particulate monitoring at natural disaster sites including volcanic ash, landslide dust, and demolition debris
