The TJ270-30 infrared spectrophotometer is an upgraded version of the original TJ270-30 infrared spectrophotometer from the old Tianjin Optical Instrument Factory.

The TJ270-30 dual beam proportional recording infrared spectrophotometer (upgraded version) is the first high-performance infrared spectrophotometer product in China that adopts the principle of direct proportional recording by computer. It is at an advanced level in China and occupies the main market of infrared instruments in the country.

The product fully meets the requirements of the National Pharmacopoeia and has been used in more than 700 units across the country. The instrument realizes human-machine dialogue, is easy to operate, and has complete functions. It can be widely used in various fields such as petroleum, chemical, pharmaceutical, environmental protection, teaching, materials science, public security, national defense, etc. It is an indispensable analytical and testing instrument for scientific research, production, and teaching. For users with tight budget and no specific requirements for testing time, choose.

It is also a specialized instrument for detecting hydroxyl content in the crystal glass industry. Fully comply with the national standard GB/T12442-90 for the determination of hydroxyl content in quartz glass

Our company promises free home delivery of instruments, free installation and debugging training, and provision of relevant pharmacopoeia standards and lecture operation methods. Users only need to provide sample wine. The instrument is guaranteed for one year according to national regulations and has lifelong free maintenance.

This machine is an upgraded version designed as an all-in-one machine and can be used directly without the need for a computer configuration. Resolve the issues of viruses, driver loss, laboratory space occupation, and additional expenses for users purchasing computers that have occurred in the past.
