Constant Temperature and Humidity Weighing System for Low-Concentration Sample Detection

This micro constant temperature and humidity weighing system follows the relevant requirements of the latest national testing standards HJ656-2013 \ HJ836-2017 and provides a stable environment of constant temperature and humidity for low-concentration substance detection to improve the authenticity and accuracy of the test .

Features

1. Patented constant temperature and humidity module enables the system to establish the required temperature and humidity environment within 60 minutes, which is suitable for manually weighing samples such as low-concentration sampling heads, sampling membranes and 3 # filter cartridges.

2. The system design conforms to the ergonomic principles, the space design is reasonable, and the gloves are easy to operate, which can ensure that each sample can be fully exposed to a constant temperature and humidity environment.

3. The operation box can be completely sealed to ensure isolation from the external environment and improve the accuracy of the test data.

4. The airflow in the operation box is designed to be sent up and down, and the circulation is unidirectional. The circulation fan is a high-speed axial flow fan, and the airflow surface is designed with a uniform flow film and other mechanisms to ensure the uniformity of the airflow in the cabin.

5. The refrigeration system adopts the design of integrated transportation and split operation, which is convenient for transfer and overcomes the weighing error caused by the compressor system vibration.

6. The operation of the inner bin is made of stable performance materials to avoid secondary contamination of the sample by the inner bin material.

7. Automatic constant temperature and humidity weighing system also has:

8. Standard notebook computer.

9. Equipped with 1 / 100,000th scale as standard, it can be integrated into constant temperature and humidity system according to customer's designated brand.
