Product Description
The UV-Vis Spectrophotometer YG0895, YG0896, and YG0897 models are engineered to deliver precise and reliable spectrophotometric measurements across a wide wavelength range of 190-1100 nm. These models vary in bandwidth, with options including 1.8 nm for YG0895, 1.0 nm for YG0896, and flexible settings of 0.5, 1.0, 2.0, and 4.0 nm for YG0897. This flexibility ensures that users can select the most suitable configuration for their analytical needs.
The spectrophotometers feature exceptional wavelength accuracy (±0.1 nm @656.1 nm, ±0.3 nm) and repeatability (0.1 nm), ensuring consistent performance. Photometric accuracy is within ±0.2%T for a range of 0-100%T, and repeatability is ≤0.1%T. With a photometric range of -0.3-3A, 0-200%T, 0-9999C, these devices support a wide array of applications.
Key technical specifications highlight the instrument’s stability (±0.002A/h @ 500nm), baseline flatness (±0.0008A/h), and very low noise levels (±0.001A). Moreover, stray light is kept under control at ≤0.05%T @220 nm and 360 nm, ensuring clear and accurate readings.
