Description
Overview
GAOTek Nitrogen N2 Purity Tester is an electrochemistry gas analyzer specifically designed for measuring the purity of nitrogen gas in a range of 0 to 100% volume. It is commonly used in conjunction with nitrogen generators to ensure the quality and reliability of the generated nitrogen gas.
Features
- Rugged and durable: The instrument can effectively resist a three-meter drop. The protection level of the instrument reaches IP67
- Explosion-proof circuit design, safe and reliable: The instrument has got IECEX, ATEX, Chinese explosion-proof certificates and the explosion-proof level reaches Exia IICT4 Ga
- Multiple security protection: The man down alarm function has upgraded the safety of underground operators
