The constant temperature and humidity weighing system is a device used for precision weighing, which ensures the weighing of objects under stable conditions by accurately controlling the ambient temperature and humidity, thereby improving weighing accuracy and reliability.

This system overcomes the weighing errors caused by temperature and humidity changes, corner deviations, and human errors during the weighing process, and can automatically weigh various samples such as filter membranes, filter cartridges, and low concentration sampling heads. Weighing data can be automatically calculated, stored, queried, and exported, and can be tabular.

The constant temperature and humidity weighing system is widely used in fields that require strict environmental conditions:

1. Research laboratory: used for chemical analysis, material characterization, biopharmaceutical research and development, etc., requiring precise weighing of trace samples to ensure the accuracy of experimental data.

2. Pharmaceutical industry: used for drug formulation research and development, accurate proportioning of raw materials and formulations, moisture determination, etc., directly related to drug quality and safety.

3. Electronics and Semiconductors: Used for weighing precision components, quality control of thin film materials, and preparation of electronic chemicals.

4. Chemical industry: used for catalyst weighing, high-purity chemical batching, reactant measurement, etc.

5. Quality inspection and measurement: used for material density determination, weighing of precious metals in jewelry, calibration of standard substances, and detection of net product content.

6. Food and cosmetics: used for weighing precision ingredients, adding trace additives, etc.

7. Environmental monitoring: used for measuring the mass concentration of particulate matter such as PM2.5 and PM10, as well as for balancing and weighing the sampling filter membrane and filter head of low concentration particulate matter in fixed pollution source exhaust gas.
