Labotemp Scanning Visible Double Beam Spectrophotometer NSP-04 provides accurate visible range photometric analysis for laboratory testing, quality control, environmental monitoring, food analysis, medical testing, and petrochemical applications. Designed with double beam ratio detection, the instrument operates across a 320 to 1100 nm wavelength range with a 2 nm spectral bandwidth and automatic wavelength setting.
The spectrophotometer combines a high performance optical system with a 1200 lines/mm grating, photodiode detector, tungsten light source, and 128 × 64 bit LCD display. Built in analysis functions support standard curve creation, continuous testing, data storage, and direct display of test results. USB data output and optional software support online operation, while the sample compartment accommodates cuvettes in different sizes for varied laboratory requirements.
