Ambient Air Comprehensive Sampler

Product Overview

The HD-H7 (Model H7) Environmental Air Integrated Sampler is an indispensable instrument for capturing particulate matter (TSP, PM10, PM2.5, etc.) and various gas components (SO2, NOx, etc.) from the atmosphere. During development, opinions from experts and a wide range of users were extensively collected, and high technologies in the fields of computers, sensors and new materials were applied, resulting in reliable quality, stable performance and a long service life.

Application Range

The sampler uses the solution absorption method to collect various harmful gases in ambient and indoor air, and uses the filter-membrane gravimetric method to capture total suspended particulates (TSP) and inhalable particulates (PM10 or PM2.5), fluoride, heavy metals, SVOC, etc. It can be used by environmental protection, health, labor, safety supervision, military, scientific research and education departments for routine and emergency monitoring of gaseous substances and aerosols.

Technical Features

1. Multiple uses in one instrument: free combination of medium-flow sampling, low-flow heating, low-flow thermostatic and micro-flow sampling modes, with independent control and flexible configuration.
2. 7.0-inch wide-temperature high-brightness color touch display, clearly visible in sunlight, with a beautiful interface and convenient operation.
3. Dual operation mode of keys and touch, adapting to the operating habits of various users.
4. Optional built-in rechargeable lithium battery; a single charge provides more than 4 hours of working time.
5. Massive data storage: more than 100,000 data records.
6. Particulate sampling flow (10-130) L/min, settable; with the corresponding sampling head, it can be used for sampling fluoride, heavy metals and SVOC.
7. Imported sampling pump with high load capacity, low noise, stable flow and long service life.
8. Automatically measures pre-meter temperature and pre-meter pressure and automatically calculates the standard-condition sampling volume.
9. Small size, light weight and convenient to carry.
10. Automatic data protection when power fails during sampling; sampling continues after power is restored.
