1Constant temperature and humidity weighing systemApplication field

Atmospheric particulate matter monitoring

In the sampling and analysis of atmospheric particulate matter (such as PM2.5, PM10), a constant temperature and humidity weighing system is used to accurately measure the weight of the filter membrane before and after sampling. By balancing the filter membrane in a constant temperature and humidity environment, the influence of environmental factors on the weighing results can be eliminated, ensuring data accuracy and providing reliable basis for environmental air quality assessment.

Fixed pollution source exhaust gas monitoring

The constant temperature and humidity weighing system can meet the requirements of relevant standards and improve the accuracy of weighing in the sampling filter membrane, filter head balance, and weighing process of low concentration particulate matter in fixed pollution source exhaust gas.

Study on the Stability of Environmental Samples

In environmental monitoring, some samples (such as soil, water samples, etc.) are sensitive to temperature and humidity. A constant temperature and humidity weighing system can provide a stable weighing environment, ensuring that the properties of the samples do not change during the weighing process and ensuring the reliability of the monitoring results.

2、 Advantage analysis

Improve weighing accuracy

Environmental factors such as temperature and humidity fluctuations can cause small changes in object weight, which in turn can affect weighing results. The constant temperature and humidity weighing system precisely controls the ambient temperature and humidity to maintain them within a stable range, minimizing the impact of these fluctuations and thus improving weighing accuracy.

Enhance experimental reproducibility

Weighing under constant environmental conditions can reduce experimental errors, improve the reproducibility and reliability of experimental data. This is particularly important for data that requires long-term tracking and comparison in environmental monitoring.

Suitable for sensitive samples

For environmental monitoring samples that are highly sensitive to environmental conditions, a constant temperature and humidity weighing system can provide an ideal weighing environment, avoiding changes in the properties of the samples due to environmental changes and ensuring the accuracy of monitoring results.

Meet the standard requirements

The constant temperature and humidity weighing system can meet the requirements of relevant environmental monitoring standards, such as national standards HJ836-2017 and HJ656-2013, to ensure the legality and validity of monitoring data.

improve work efficiency

The constant temperature and humidity weighing system has automatic control and data management functions, which can record weighing data in real time and export the data to a computer through a data transmission interface. It can use supporting software for data analysis and processing, generate required charts, reports and other files, and improve work efficiency.
