Harbin YudaNon woven fabric online thickness gauge/film infrared online thickness gaugeAccurate measurement. Based on the parameters collected over the years, our company has established a large number of data models to help measure the parameters. The establishment of predictive models is beneficial for simplifying the measurement process and effectively reducing errors.

The HYD-8C coating online thickness gauge adopts near-infrared light irradiation technology, which can continuously and non-contact detect coating thickness online. It is easy to operate, stable and accurate. Based on the parameters collected over the years, our company has established a large number of data models to help measure the parameters. The establishment of predictive models is beneficial for simplifying the measurement process and effectively reducing errors.

1. The online coating thickness gauge is important in the production process of adhesive products, as it can measure the thickness of water glue, oil glue, and hot melt glue online.
2. The coating thickness detector is directly installed above the coating head through a scanning frame, which can detect whether the coating thickness is standard and uniform, reduce the waste of unqualified products, improve product quality, reduce raw material consumption, and greatly increase production efficiency and output. And it avoids the sampling and testing process of semi-finished products, reducing the number of broken ends.
3. Near infrared spectroscopy (NIR) analysis technology is a rapidly developing analytical technique in the field of analytical chemistry. NIR spectroscopy belongs to the second harmonic and main frequency absorption spectra of molecular vibration spectra, mainly due to the non resonant nature of molecular vibration, which causes molecular vibration to transition from the ground state to energy, and has strong penetration ability. It is increasingly attracting the attention of internal and external analysts, and is known as the "giant" of analysis in the field of analytical chemistry. Its emergence can be said to have brought about another revolution in analytical technology.
4. The online detection system using near-infrared spectroscopy technology has the advantages of non-contact and fast measurement speed.
