Visiable Spectrophotometer

La description

Application scope: The instrument is widely used in medical and health, clinical examination, biochemical, petroleum chemical, environmental protection and quality control departments, etc. Characteristics: LCD graphic display clearly showing the testing results and the prompt of operation process externally linked to a thermal sensitive printer printing out the testing results and process and store data. There are three testing modes: photometer mode, wavelength scanning, quantitative analysis in which there are three analytical methods: coefficient , one point method and multi-points underdetermination, dynamic analysis and multiwavelength testing mode Special cuvette pairing function be able to eliminate measurement error from cuvette pairing ( available in photometer mode and quantitative analysis only) Automatic zero setting / full scale set function High precision, good reproducibility and stability Stand for the different needs from our customers, choose different wavelength interval to sample 0.1nm/0.2nm、0.5nm/1nm/2nm/4nm.
