（For detailed product information, please contact the product owner to provide you with detailed product parameters and pictures

Product Overview

RG-AWS7H with drying constant temperature and humidity weighing system is a high-precision constant temperature and humidity system that automatically dries the sample to be weighed at 105 degrees Celsius, and the drying time can be set; After drying, the sample is automatically collected, unloaded, and weighed using a fully automatic intelligent system. This system overcomes weighing errors caused by factors such as temperature and humidity changes during manual operation, changes in the placement of weighing trays, and reading errors. It can simultaneously weigh 47mm filter membranes and low concentration sampling heads. The data of sample weighing can be stored, queried, and implemented in a tabular format, saving time,reduceThe intensity of labor. The entire weighing process strictly follows the standards of the Ministry of Environmental ProtectionThe requirements specified in HJ618-2011, HJ656-2013, and HJ836-2017 "Determination of Low Concentration Particulate Matter in Fixed Source Waste Gas" are important equipment for weighing and quality control of atmospheric particulate matter and pollution source sampling samples. They can be used for high-precision weighing of sampling samples for atmospheric source analysis projects and pollution source sampling samples.

The system can be optionally equipped with our company's independently owned intellectual property (low concentration sampling head) rapid laminating machine, featuring a claw type pressing structure and rapid prototyping, without the need for a power supply.

Note: The above configuration cannot be used for weighing bottles, drying dishes, filter cartridges, and other samples of other specifications. It is only used for weighing the above five samples and requires manual replacement of the carrier.

7. The sample is equipped with a digital code that can be recognized by the human eye and a barcode that can be automatically recognized by the system. The filter membrane adopts an integral weighing filter membrane with barcode and digital code, which integrates sampling, transportation, and weighing without separation.

8. Software function: A dedicated weighing system Chinese software that meets the requirements of the national HJ836-2017 standard for the determination of low concentration particulate matter in fixed source exhaust gas by weight; The software supports manual balance calibration; The software has the function of manually loading and unloading samples on the disc; The software has the function of supplementing sample numbers; The software has the function of automatically calculating concentration by inputting sampling volume; The software can independently view the initial weight, final weight, and comprehensive table of current or historical batches to create standard membrane calibration values.

9. Sample anti-static time<15s (set according to customer requirements)

10. The system has good grounding and grounding markings, and is powered by an AC220V, 50Hz power supply with a power of 3.5KW

11. Dimensions: 1300 * 780 * 2000 (length * style * height unit: mm) for easy installation in the laboratory
