Particulate matter monitorAQMS-900C-PM₂.₅

Product Description

AQMS-900C-PM₂.₅ particle monitor uses the principle of beta ray absorption to monitor the concentration of fine particulate matter PM₂.₅ in the air. The system configuration includes a cutting head, filter membrane, and calibration membrane. Beta rays are a high-speed electron stream. When it passes through particulate matter, part of the energy is absorbed by the particulate matter, causing the intensity to attenuate. The attenuation of low-energy beta rays is only related to the mass of the absorbing material and has nothing to do with other physical properties (such as particle dispersion, color, gloss, shape, etc.). Therefore, by measuring the attenuation of beta rays, the amount of air in the atmosphere can be calculated. The mass concentration of particulate matter.

Features

It has the "automatic calibration" function, which can realize non-manual and non-mechanical automatic calibration work;

It has a "filter band error elimination" function that can eliminate measurement errors caused by different filter bands;

It has intelligent dynamic paper saving function and filter paper replacement reminder function, which effectively reduces the usage of filter paper and saves operating costs;

It has dynamic dehumidification and humidity compensation functions to effectively eliminate the impact of humidity on measurement;

Optional bypass gas circuit design provides manual comparison interface, allowing manual and automatic sample retention;

The sample gas flow closed-loop control system is adopted to ensure the accuracy of the flow rate during long-term operation;

The large-screen touch LCD can display working condition concentration, standard condition concentration, historical data, calibration records and other information.
