Universal refractometer DD-7

optical

Model DD-7 Low concentration aqueous solution can be measured with high accuracy. Digital Differential Refractometer DD-7 This model measures solutions of low concentration up to 2% at an extremely high accuracy level of ±0.005%. It is recommended for such samples as unsweetened tea and surfactants. 2 types of solutions – distilled water as the standard solution and the sample liquid to be measured – are injected into the instrument with syringes.By using a standard solution other than distilled water, solutions of higher concentration can also be measured. Specifications Model:DD-7 Cat.No.:3930 Method of measurement:Differential optical refraction Range:0.000 to 2.000% for sucrose solution.it is possible to measure samples with refractive index up to 1.50 (nD) by reference solutuion. Resolution:Brix : 0.001% Accuracy:Brix : ±0.005 (for sucrose solution at 30°C) Measurement Temperature:15.00 to 40.00℃ Dimensions & Weight:36×35×14cm, 6.2kg Output:• Digital Printer DP-AD (Optional) • RS-232C Options · Digital printer DP-AD (Dot matrix printer) : Cat.No.3123 · 0.25% Sucrose (±0.005%) : RE-11025D · 0.50% Sucrose (±0.005%) : RE-11050D · 1.00% Sucrose (±0.005%) : RE-11100D · Low concentration Optional Sucrose Solutions below 2.000% (±0.005%) : RE-172030
