Hanna HI93703-57 校正甘油，4 x 30mL

The HI93703-57 is a reagent grade glycerol reference standard used in the calibration of the HI96785 Honey Color Analyzer and HI96759 Maple Syrup Photometer. The glycerol is used to calibrate the photometers to 100% transmittance. A honey or maple syrup sample is then tested to determine the amount of light, at a specific wavelength, can be transmitted relative to the glycerol standard. The % transmittance is then used to grade the appropriate product. For honey the results are reported as pfund mm while for maple syrup % transmittance is used. The HI93703-57 is for 4 bottles containing 30 mL of glycerol.
