The Nitrogen Purity Meter(NPM250) is designed to measure the concentration or purity of nitrogen gas in a given environment. It is commonly used in industries such as food packaging, pharmaceuticals, electronics, and chemical manufacturing, where nitrogen gas is used for various applications.

The NPM 250 employs an Electrical Conductivity(EC) sensor technology to determine the percentage of nitrogen in a gas mixture or atmosphere. This measurement is displayed on a digital screen, providing real-time readings for easy monitoring and control.

In the food packaging industry, nitrogen is often used as a gas to displace oxygen and extend the shelf life of packaged products. The nitrogen purity meter ensures that the nitrogen gas used for this purpose is of the desired purity, maintaining the integrity and freshness of the packaged goods.
