Differential refractometer DD-7

laboratorybenchtop

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. 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
