Shanghai Jingke 722S Visible Spectrophotometercharacteristic:
◆ It has a wider spectral range, including the 340nm~400nm near ultraviolet range and 800nm~1000nm near infrared range commonly used in modern colorimetric analysis, biochemical analysis, and enzyme analysis, making it particularly suitable for analytical chemists to apply.
The streamlined shape, Lingqiao's volume, beauty, and resistance to chemical solvents of the internationally popular paint are particularly suitable for modern laboratory environments.
Through the RS232C interface, peripheral devices such as computers and printers can be connected, and optional software packages can be used for further expansion.
The keyboard operation is simple and clear, which can easily achieve automatic adjustment of 0% (τ), automatic adjustment of 100% (τ), and error free τ/A conversion. It has factor setting and concentration setting direct reading functions.
Pre adjusted light sources and modular modular design provide maximum convenience for users' maintenance and modular maintenance.
The overall aluminum alloy pressure casting base, mirror seat and holographic grating, C-T monochromator, and non spherical mirror optical system will bring you stable performance and durable and reliable quality.
