Spectrophotometer
722Y type visible
spectrophotometer
Instrument introduction:
1.
using advanced computer processing
technology, automatic tone 0%, tone
100%, error free T / A conversion,
direct-reading concentration function.
2. using 1200 / mm high
performance grating, wavelength
accuracy, good monochromaticity, low
stray light.
3. the use of imported
tungsten lamp, a higher luminous
efficiency, longer service life, lower
power consumption.
4. specific 4nm
bandwidth, compared with similar optical
instruments, test performance.
5. large sample room, can
choose to place the 100mm colorimetric
utensil, particularly suitable for power
plant, sugar refinery for trace
analysis.
6. with RS232 interface,
can be connected to the computer or
directly connected to the printer.
7. 722YS
spectrophotometer is a 722Y export
oriented, based on the 722Y made
improvements.
