Models of Visible Spectrophotometer

Labtron visible spectrophotometers have high-resolution grating systems that span a broad range of wavelengths. They use light sources that are adaptable and silicon photodiode detectors for accurate measurements. These offer numerous modes, including transmittance, absorbance, concentration, and autocalibration. They include USB and RS232 connectors and big LCD screens. Our visible spectrophotometers offer excellent measurement stability and precision for use in industrial applications and research.
