Model JK-VS-723N - Visiable Spectrophotometer



The instrument is widely used in medical and health, clinical examination, biochemical, petroleum chemical, environmental protection and quality control departments, etc.

  • 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 input, 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.
