REF120 0 TO 35% Brix,Digital This protable refractometer is a precision optical instrument which is designed to measure the concentration of soluble solids(almost 100% sugar) in aqueous solutions of fruit juice and other materials.The unit features automatic temperature compensation(ATC) Which make temperature corrections unnecessary between 0 to 40 degree(32~104 oF).It utilizes the standardized Brix scale which is accurate and easy to read. The digital display is quick and easy to read Brix readings. Measurement range:0 to 35% Brix Nd 1.3330 to 1.3903 Accuracy: ± 1 %Brix Nd 0.0003 Temperature Measurement Range:0 to 40 ℃. Operation Temperature : 0 to 35℃. Power Supply :9V battery Alarm of low voltag |
