HM-H5 Enhanced Comprehensive Air Sampler

Product Introduction

The HM-H5 is an enhanced comprehensive air sampler from HM Instruments designed for environmental monitoring and research applications that require simultaneous particulate and gaseous pollutant sampling. Integrating three independent sampling channels — a constant-temperature constant-flow channel, a micro-flow constant-flow channel (0.020–0.300 L/min) specifically for VOCs sorbent tube collection, and a particulate sampling channel (10–130 L/min) — the HM-H5 enables multi-parameter air quality assessment in a single deployment. The instrument automatically measures pre-gauge temperature, pre-gauge pressure, and atmospheric pressure to calculate standard-condition sampling volumes in real time. With flow accuracy better than ±2.0%, sampling time accuracy better than ±0.2%, and noise below 60 dB(A), the HM-H5 delivers reliable data quality for research laboratories and educational institutions. Its compact 165×330×275 mm footprint and approximately 4.0 kg weight make it easily portable for field campaigns, while dual AC/DC power options ensure operational flexibility.

Applications

• Ambient air quality monitoring — TSP, PM10, and PM2.5 particulate matter collection

• VOCs sampling — sorbent tube-based volatile organic compound collection at micro-flow rates

• SO2 and NOx absorption bottle sampling via constant-temperature constant-flow channel

• Environmental research — multi-parameter atmospheric characterization in field studies

• University and college teaching laboratories — air quality measurement demonstrations

• Industrial hygiene assessments — workplace ambient air contaminant sampling

• Environmental impact assessment — baseline and compliance air quality data collection

Features

1. Three independent sampling channels: constant-temperature constant-flow, micro-flow constant-flow, and particulate — all in one instrument.

2. Micro-flow constant-flow channel (0.020–0.300 L/min) specifically supports VOCs sorbent tube sampling for volatile organic compound analysis.

3. Particulate sampling flow range (10–130 L/min) with accuracy better than ±2.0%, covering TSP, PM10, and PM2.5 cutting heads.

4. Constant-temperature constant-flow channel maintains stable sample temperature for gaseous pollutant absorption methods.

5. Flow stability better than ±2.0% across all channels ensures data reproducibility between sampling sessions.

6. Automatic measurement of pre-gauge temperature, pre-gauge pressure, and atmospheric pressure for real-time standard-condition volume calculation.

7. Sampling time range 1 min to 99 h 59 min with accuracy better than ±0.2% for extended and short-duration sampling programs.

8. Dual power supply: AC 220 V ±10% 50 Hz and DC 29.4 V / 5 A, supporting both laboratory and field deployments.

9. Compact dimensions (165×330×275 mm) and lightweight design (~4.0 kg) for easy transport between monitoring sites.

10. Low noise operation below 60 dB(A) suitable for indoor and residential-area monitoring without disturbance.

11. Power consumption below 100 W for energy-efficient long-duration sampling campaigns.
