TR-VS-721N
Visiable Spectrophotometer TR-VS-721N
Attemptation scope:Spectrophotometer can quantitatively analyze material content in the range of visible spectral to many institutions•It is a kind of routine testing equipment in industries of the steel smelting, food testing, environmental monitoring, universities, paper electroplating, printing and dyeing, and electric power.
Characteristics:
- Wavelength range ( 335-1000) nm,
- Built-in Single-Chip coumputer, high automaticity instrument, automaticly adjust 0%(), automaticly adjust 100%() and zero tolerance -A switching, more handy than the original 721 model.
- LED digital display
- 4 modes of measurement: transmittance(), absorbance(A), direct reading of concentration(C) and confficient determination(F), completely comply with testing requests.
- Advanced optical system,superior C-T model monochromator'''s beamsplitter highly optimize these indexs :resolution, photometric accuracy, stray light.
- Appropriative precision presetting lamp or a lamp holder. Our users don'''t need to readjust light path when changing the lamp. It will be more handy for our users.
- Sample room is made of special engineering plastic bearing solvent and strong sour alkali. In the bottom side installed a removable a container for liquid to meet needs of some of our users.
