The Model DR-A1, with its digital display, provides the user with a precision instrument for the Brix and Refractive Index (nD) analysis of liquids, glass, plastic, & film.
Easy to Use
Operation consists of placing a sample on the prism. While looking through the eyepiece, the control knob is turned until the shadowline is centered in the crosshairs (see image "Eyepiece View"). The reading is shown on the large LCD display. Calibrates with water or the included 1.5163 nD glass standard.
Digital Accuracy
High resolution and accuracy provides substantial precision for both liquid and solids testing. The digital display and simple operation both enhance overall precision - no analog scales to read.
Professional Features
Large, menu-driven LCD display; Refractive Index (nD) & Brix scales; primary & secondary prisms; color compensator dial; large measurement dial; focusable eyepiece; external power supply; desiccant case; drain nozzle.
LED Light Source
Long-life LED light source can be set for upper and lower settings enabling both transmission and reflection measurement modes.
Prism Temperature Control
Featuring 2 circulator nozzles for the primary prism and 2 for the secondary prism. Model DR-A1 can be connected to a circulating bath to accurately regulate prism temperature. The prism temperature is displayed on the LCD display. The effective temperature range is 5-50°C.
Automatic Temperature Compensation
Features Automatic Temperature Compensation with 20°C as the reference point. Available for the Brix scale only. the effective compensation range is 5-50°C.
Glass, Plastic, & Film Testing
Transparent or translucent film samples can be measured with the use of the included bromonaphthalene contact liquid and the optional film measurement set (Catalog No. RE-1581). Note: The refractive index (nD) of the sample must be lower than that of the contact liquid. The included bromonapthalene contact liquid has a refractive index (nD) value of 1.6300.
Double Refraction (Birefringence) Testing
With the optional polarizing eyepiece (cat. no. RE-1145). Model DR-A1 can test samples exhibiting double refraction. For example, a piece of film with this characteristic would have a machining direction (V axis), a right-angle to machining direction (X axis), and a thickness direction (Z axis) - the refractive index must be measured for each axis.
