Principles for selecting atmospheric samplers

2024-03-04 14:37

The atmospheric sampler plays a good role in detecting harmful gases in the air and environment. With the continuous progress of science and technology, new products are constantly being introduced for atmospheric samplers, such as intelligent atmospheric samplers, explosion-proof atmospheric samplers, dual gas path atmospheric samplers, and so on, greatly enriching the classification of atmospheric samplers.

The atmospheric sampler is just a part of the sampling instrument, and there are also individual samplers, dust samplers, dust and toxin samplers, explosion-proof samplers, etc.

Product features:

1. Compact in size, convenient to use, and easy to carry.

2. The volumetric vane pump made of imported DC brushless motor is used as the sampling power in China, with high suction negative pressure, stable flow rate, and long fault free operation time.

3. This product adopts CPU control, which is easy to use and reliable in performance.

4. This instrument is dual-purpose for AC and DC, and has a low-temperature sampling function. When working in a low-temperature environment, the sampler circuit is heated by an automatic constant temperature heater controller to ensure operation at a constant temperature.

Selection principle:

1. The nominal diameter of the sampling tube should not exceed 15mm.

2. Fixed top tanks should be of float (ball) type.

3. Folding type should be selected for floating roof tanks and inner floating roof tanks.

4. When the medium is jet fuel, the material of the sampling tube should be stainless steel or aluminum alloy.

5. When the liquid level is below 4M, sampling is generally not conducted. Users should fill out the technical data sheet of the sampler in detail.
