Atmospheric SamplerAn instrument or device for collecting atmospheric pollutants or contaminated air. They come in various types, which can be categorized by the collection object into gas samplers and particulate matter samplers; by the place of use into environmental samplers, indoor samplers, and source samplers. Additionally, there are specialized atmospheric samplers, such as those that collect both gases and particulate matter simultaneously. A gas sampler typically consists of a collector, a flowmeter, and an air-extraction power system.
Atmospheric samplers play a crucial role in detecting harmful gases in air and the environment. With the continuous advancement of science and technology, new products such as intelligent atmospheric samplers, explosion-proof atmospheric samplers, and dual-gas-line atmospheric samplers are being launched, significantly enriching the classification of atmospheric samplers.
This is a commonly used instrument for collecting atmospheric and workshop gases. It is widely applicable in atmospheric environment monitoring, health and epidemic prevention, labor protection, and scientific research units, and can also be used in conjunction with other instruments. By analyzing the sampled gases, it helps to understand the extent of environmental pollution by harmful gases and provides the relevant authorities with the actual situation of pollution to take countermeasures, thereby ensuring a healthy living environment for people.
Use Requirements for Atmospheric Samplers:
To prevent accidental connection to other industrial power sources, in order to avoid damaging the sampler and potentially causing personal injury.
2. Power the sampler on after the power supply is reliably connected; do not use the sampler to check if the power is connected!
Weekly constant temperature and flow samplers require regular calibration of the flow rate.
4. Do not start the machine without installing the test fluid. Dust and debris can be吸入 into the sensor and sampling pump, damaging the sampler.
Avoid excessive vibration, impact, and exposure to dust, rain, and snow during transportation and use.
After on-site sampling, handle the collected samples with care, gently and avoid contamination or shedding.
Sample flow should be maintained at a constant rate of 20L/min to ensure optimal collection efficiency of the pre-catcher for respirable dust, as deviation from this rate may affect the accuracy of the measurement.
Power off the device and wait for at least 5 seconds before turning it back on.
