Comprehensive Ambient Air Sampler

Comprehensive Ambient Air Sampler

  • Product Number:LD-H7
  • Product Difference:Particulate Matter Sampling Flow Rate (10–130) L/min, Dual-Channel Constant-Temperature Constant-Flow Atmospheric Sampling

Product Introduction

The Ambient Air Sampler (hereinafter referred to as the sampler) is an essential instrument for capturing particulate matter (TSP, PM10, PM2.5, etc.) and various gaseous components (SO₂, NOx, etc.) in the atmosphere. Developed through extensive consultation with experts and users, this sampler incorporates cutting-edge technologies in computing, sensors, and new materials, ensuring reliable quality, stable performance, and extended service life.

The Environmental Air Sampler employs solution absorption methods to collect various harmful gases from ambient and indoor air. It utilizes filter membrane weighing techniques to capture total suspended particulates (TSP), inhalable particulates (PM10 or PM2.5), fluorides, heavy metals, SVOCs, and other substances from ambient air. Suitable for routine and emergency monitoring of gaseous substances and aerosols by environmental protection, health, labor, safety supervision, military, research, and educational departments.

Product Features

  • Multi-functional design with dual constant-temperature, constant-flow atmospheric sampling channels and one TSP sampling channel, featuring independent control and flexible configuration.

  • Equipped with imported sampling pumps offering high load capacity, low noise, stable flow rate, and extended service life.

  • High-vacuum imported blower delivers load capacity exceeding 20kPa at 100L/min.

  • Dual operation modes—button and touch—accommodate diverse user preferences.

  • 7.0-inch wide-temperature high-brightness color touchscreen offers sunlight readability, intuitive interface, and user-friendly operation.

  • Adjustable particulate sampling flow rate; compatible with specialized sampling heads for fluoride, heavy metals, SVOCs, and other applications.

  • Dual data output modes: Bluetooth printing or USB export.

  • Massive data storage capacity exceeding 100,000 sets.

  • Compact size and lightweight design for easy portability.

  • Aluminum alloy sampling head resists static adsorption.

  • Automatically measures temperature and atmospheric pressure, calculating standard-condition sampling volume.

  • Automatically protects data during power outages and resumes sampling upon power restoration.

  • Excellent dustproof and waterproof design ensures reliable operation in rainy or snowy conditions.

  • Electromagnetic compatibility (EMC) design provides strong resistance to interference and radiation.
