| The Brix concentration, Refractive index or other parameters are always needed in lab or our life. The traditional optical refractometer is very popular used to measure these parameters. Compared with the traditional optical refractometer, the digital refractometer with a digital readout and LCD display will eliminate uncertainties and is more convenient to use. Just about 0.3ml-0.5ml sample was needed. The result will be showed in the display! With smart and beautiful shape, our Pocket digital refractoemeter will be a good instrument in your work!MODEL:PDR40W SCALES:BRIX,AP,Oe,KMW RANGE:BRIX 0-40%AP 0-22Oe 0-150KMW 0-25 DIVISIONS:BRIX 0.1AP 0.1Oe 1KMW 0.1 ACCURACY:BRIX ±0.1AP ±0.1Oe ±1KMW ±0.1 Original:BRIX 0AP 0Oe 3KMW 0The digital refractometers have the following characters:Automatic Temperature CompensationAutomatic Shut Off after 3 minutesConversion between Centigrade and Fahrenheit Degree Alarm of Low Voltage & Low power co |
