JK-VS-723A Visiable Spectrophotometer
The instrument is widely used in medical and health, clinical examination, biochemical, petroleum chemical, environmental protection and quality control departments, etc.
Adopting microcomputer technology, automatic adjustment“0”“100” can directly eliminate cuvette’s matching error.
High precision,good reproducibility and stability
It has functions of concentration direct reading, linear regression, timing printing, GOTOλ and spectral scanning,another specific functions followed by the needs of our customers.
Equipped many optional attachments,such as different general cuvettes and semimicro cuvettes, micro automatic operational temperature bath etc.
Can output to printer or PC standard (RS232)
