ultraviolet and visible spectrophotometer
752N
The company's 752N UV-VIS spectrophotometer is based on the 722 visible spectrophotometer to increase the ultraviolet light source deuterium lamp, and the working wavelength to short wave extended to 200nm, greatly expanded the scope of application of the instrument, become a more powerful spectrophotometric general instrument. The instrument can perform direct reading determination of transmittance, absorbance and concentration in the wavelength range of 200nm ~ 960nm, and can be connected to a printer for printing or access a PC program to perform more functions. This instrument can be widely used in medical and health, biochemistry, clinical biochemistry, environmental monitoring, food testing, petrochemical, basic teaching laboratory of colleges and universities and other departments of quantitative and qualitative analysis.
1) 32-bit ARM single-chip microcomputer system, strong function, small size, easy maintenance
2) The use of flame retardant, insulated all-plastic shell, exquisite shape design, easy operation, high safety factor
3) True 4-bit LCD display, large measuring range, high calculation accuracy.
4) Film keyboard, feel good, dustproof, waterproof, easy to clean
5) Advanced optical system design, sealed grating monochromator, and the adoption of scientific anti-mildew technology, anti-stray light technology, significantly improve the service life, stray light, stability and metering accuracy indicators
6) Tungsten halide lamp and deuterium lamp use lens to concentrate light, to avoid the linear decline of energy after the reflection mirror is burned for a long time
7) Special precision lamp holder, can be replaced by tungsten halide lamp and deuterium lamp, do not need to adjust the light path again
8) Switch tungsten halide lamp and deuterium lamp with the button, easy to use, safe and energy saving.
9) Automatic adjustment 0%, automatic adjustment 100% and absorbance 0A
10) With "concentration direct reading" and "concentration factor" functions
11) With RS232 port, can be external micro thermal printer (optional)
Can be connected to PC through RS232 port, with powerful PC software for purchase
