เครื่องโฟโตมิเตอร์-สี, ทินท์, ฟีนอลในไวน์ (Determination of Color and Total Phenols in Wine Photometer)

HI 83742

Photometer for the Determination of Color and Total Phenols in Wine

          HI 83742 is a dedicated photometer engineered to measure total phenols and the color and tint of wine. Extremely easy to use, this instrument affords quick and accurate analysis. At the touch of a button, users can select the range of operation. In order to measure color, tint and total phenols, HI 83742 is equipped with 3 independent optical channels. Each channel has a specialized tungsten light source and a narrow band interference filter. The filters are 420 nm, 525 nm and 610 nm. The analytical procedure to measure these parameters requires calculation of ratios at different wavelengths. HI 83742 automatically calculates the often time-consuming and complex equations – so that you don’t have to – and provides direct results.

Order Information:
HI 83742 is supplied with reagents for 5 tests, 2000 µl pipette, 200 µl pipette, 1 ml pipette, 3 ml pipette, 5 ml syringe, (2) cuvets with caps, tissue for wiping cuvets, 12 VDC power adapter, (4) 1.5V AA batteries and instruction manual in a hard carrying case.
