Product Description:
1. The company has passed the IS09001 quality management system certification and established a complete special gas measurement and testing system to ensure the standardization of the production process and product quality of ethylene oxide standard gas.
2. The standard gas production implements “every bottle must be inspected” and uses multiple high-end testing equipment to ensure accurate and stable measurement values.
3. More than 50 kinds of standard gases produced by the company have obtained the national secondary standard material certificate, and the measurement values are reliable.
