Visible spectrophotometer 722N/S single beam - 722N

UV Vis Spectrophotometer,Flame Photometer, Polarimeter,Whiteness Meter, Turbidity Meter,Refractometer, Colorimeter, Tintometer

this model is latest design following the model 721.it is a standard instrument which based on the principle of spectrophotometry.it can measure the transmittance,absorbency,concentration factor and concentration direct reading of samples within 340nm ~1000nm wavelength ranges.it can be easily connected printer or PC procecss.it is widely apply to clinical sanitation,biochemistry,envrionment protection,food inspection,petrochemical,tertiary institutions,basic teaching expertiments,etc.

Charateristics:

4 digital LCD display.thin-film-style keyboard,dust-proof,water proof and easy to clean.

it adopt lens to gathering light.

with a professional lamp holder to avoid the readjusting optical path after you replacing the burnt lamp.

automatic calibration 0%(T),100%(T),and absorbency0(A).

with RS 232 interface
