Abbe Refractometers
DR and T-Series Models

The ATAGO Model DR-A1 Digital Abbe Refractometer features digital readout of either Brix or Refractive Index (nD), electronic prism temperature measurement, nozzles for connection to a circulating constant temperature bath, and Automatic Temperature Compensatioon (5-50°C).

The DR-A1 combines high accuracy [±0.0002 for refractive Index (nD), ±0.1% for Brix] and a  wide range [1.3000-1.7100 for Refractive Index (nD), 0.0-95.0% for Brix]. The LCD display is the largest available on similar refractometer models and displays both the reading and prism temperature as they occur.

OPERATION IS SIMPLE
  1. Place on the prism and close the cover
  2. While looking through the eyepiece, rotate the adjustment control knob until the shadowline in centered in the crosshairs
  3. The reading and prism temperature are displayed on the LCD screen.

In addition to aqueous samples, the DR-A1 can also be used to measure the refractive index (nD) of solid (i.e. glass, plastic, film, etc.) The DR-A1 is also capable of measuring in either transmission or reflexion modes by use of the delta-ray wavelength.

T SERIES
Model 1T Abbe Refractometer
Features a digital thermometer, built-in light source, nozzles for connection to a circulating constant temperature bath, and high-level optics. When used with a water bath, the effective temperature range is 0-50°C. Model 1T's high accuracy and Standard features make it ideal for most laboratory setting.

Model 2T Abbe Refractometer
Features a digital thermometer, built-in light source, nozzles for connection to a circulating constant temperature bath, and high-level optics. When used with a water bath, the effective temperature range is 0-120°C. Model 2T is specifically designed for working with high-temperature samples.

Model 3T Abbe Refractometer
Performs with the highest level of accuracy but is also easy to use. The 3T is equipped with all of the following high-end features: four-position lighting an oversized scale, coarse & fine control knobs, a high accuracy digital thermometer, high-level optics, and a built-in air dryer and moisture removal device. When used with a water bath, the effective temperature range is 0-50°C.

Model 4T Abbe Refractometer
Features a high refractive index (nD) range (1.4700-1.8700), a digital thermometer, built-in light source, nozzles for connection to a circulating constant temperature bath, and high-level optics. When used with a water bath, the effective temperature range is 0-50°C. Model 4T is perfect for research on any new compounds with unusually high refractive indices; also ideal for work with polymer film and related materials.
