Portable Monitoring Instrument






WithTech possesses equipment that is mainly used in the fields of molecular contamination monitoring and the metal pollution level during the wafer washing process.

Compared to the ones by other companies, the products of WithTech have been proven for their excellent elimination of residual concentration influence, precision, and sensitivity as well.

As a result, the company is now working with various LCD manufacturers including Samsung Electronics and Hynix for the monitoring of clean rooms and the production process.

NaVi-SM301, a portable monitoring instrument that measures ammonia gas level, is capable of quickly measuring the gas at the level of ppt.

This molecular contamination monitoring device checks for ammonia gas which causes T-top defect and the lens haze contamination of manufacturing equipment.

Once NaVi-SM301 is properly adapted to FAB and manufacturing monitoring, not only is the management of pollution sources more convenient, but also cost-savings are possible due to better productivity and efficiency.

NaVi- EM201, a portable acidity monitoring measuring instrument is highly praised for its world-best sensitivity for acid gas which results in peroxidation of a wafer, troubles in the current leak, and corrosion of the equipment.

It is also able to measure more than eight pollution sources at the same time.
