Compact single-beam divet UV/visible spectrophotometer for routine photometry and water analysis
with screw-driven positioning and application for pesticide and water control
Ubi-490 is a compact single-beam UV/visible MicroDigital spectrophotometer for routine photometry, quantitative analysis and spectral studies of liquid and light-transmitting samples.
It measures the absorption and transmission of samples in ditches, and with additional holders it works with microvolumes of less than 500 μl, tubes, optical films and object slides. It supports photometric and quantitative analysis, spectrum scanning, multiwavelength and kinetic measurements. In positioning, the eight-millimeter aluminum base supports the stability of the optical system, and the instrument interface simplifies the settings.
Photometric system - single beam. wavelength range 190-1100 nm, spectral band 2 nm, accuracy of wavelength setting ± 0.5 nm, reproducibility 0.3 nm Photometric accuracy ±0.3%T, repeatability 0.2%T; display range 0-200%T and −0.3-3.0 A. Stability 0.002 A/h at 500 nm, scattered light ≤0.05%T at 220 and 360 nm. Sources - Deuterium and tungsten-halogen lamps, detector - silicon photodiode. output data via USB; power 220 V, 50 Hz. Dimensions 450×380×180 mm, weight 18 kg.
