Main features of the product

1. The operating software can intelligently control the instrument, set measurement parameters, collect infrared spectral data, process spectral data, export data (in text format, EXCEL), print test reports, etc.

2. Adopting the new Michelson interference principle for infrared spectroscopy measurement, the measurement accuracy is high, and a single scan only takes 3 seconds.

3. The interferometer adopts multiple sealed moisture-proof and dust-proof designs, and the visible silicone window is easy to observe and replace.

4. Equipped with a heating and dehumidification module, effectively extending the lifespan of the components inside the instrument.

5. Easy debugging, no need to open the cover to adjust the energy of the interferometer by oneself; Easy maintenance, no need to open the host to replace the desiccant.

6. Adopting a large sample accessory design, it can measure glass samples up to 300 * 300 * 20mm in size.
