722S Visible spectrophotometerDetailed product description：

The 722S visible light spectrophotometer is the latest design product after the 721 and 722 spectrophotometers. It has won the BCEIA Gold Award for universal spectroscopy and has been praised by domestic and foreign experts as a product that combines high technology and economy.

1. It has a wider spectral range, including the 340nm~400nm near ultraviolet range and 800nm~400nm near ultraviolet range commonly used in modern colorimetric analysis, biochemical analysis, and enzyme analysis
The 1000nm near red outer segment is particularly suitable for analytical chemists to apply.
2. The internationally popular paint with streamlined shape, exquisite volume, beauty, and chemical solvent resistance is particularly suitable for modern laboratory environments.
3. Through the RS232C interface, foreign devices such as computers and printers can be connected, and optional software packages can be used for further expansion.
4. The keyboard operation is simple and clear, making it easy to use automatic adjustment of 0% T, automatic adjustment of 100% T, and error free T/A conversion. It has factor setting and concentration setting
Direct reading function.
5. Pre adjusted light sources and modular modular design provide maximum convenience for user maintenance and modular maintenance.
6. The integral aluminum alloy pressure casting base, mirror seat and holographic grating, C-T unit colorimeter, and non spherical mirror optical system will bring you stable performance
Durable and reliable quality.
7. The imported integrated advanced solid silicon receiver, V/F conversion and microprocessor components enable the instrument to maintain long-term precision measurement and optimal linearity.
