UV-Vis Spectrophotometer JK 752N
Technical Specifications
The new 752N UV-Vis spectrophotometer is practical in function and easy to operate. The main unit is equipped with a digital liquid crystal display, enabling intuitive and clear readings. It automatically corrects the blank and enables error-free T/A conversion. Widely used to meet the needs of teaching and routine analysis.
Instrument Functions
- A: Absorbance testing
- T: Transmittance testing
- C: Single standard sample concentration testing
- F: Concentration testing by the coefficient method
Instrument Features
- Manual wavelength setting: With light-touch buttons, it is easy to operate and use.
- Automatic adjustment of 0%T and 100%T: Enables error-free T/A conversion.
- High-performance grating and receiver: Offers good monochromaticity, high accuracy, and low stray light.
