Dip it right in. One step closer to maximum efficiency.

  • Extremely water resistant (IP65)
  • External Light Interference (ELI)
  • Automatic Temperature Compensation (ATC)
  • Calibration with water only
  • Measurement in 2 seconds
  • Light & compact, 70g
  • Quick and easy clean



By simply setting the boundary line of refraction at the cross hairs, this refractometer directly indicates a measurement value (in refractive index or Brix (%), selective) together with the temperature on a digital display.  This refractometer enables anyone to easily carry out measurements without reading analog graduation.


  • Measurement Range:  Refractive Index (nD) 1.3000 to 1.7100; Brix 0.0 to 95.0% (Automatic Temperature Compensation is executed from 5 to 50°C).
  • Minimum Scale:  Refractive Index (nD) 0.0001, Brix 0.1%.
  • Measurement Accuracy:  Refractive Index (nD) ±0.0002, Brix ±0.1%.
  • Measurement Temperature:  5 to 50°C (at unit of 0.1°C).



This is a 2 in 1 refractometer and polarimeter hybrid unit. Brix alone can only indicate the overall amount of dissolved solids in a solution. With the RePo-1 it is now possible to know the actual quantities of each dissolved solids, such as fructose and glucose content, in a measured solution of 3ml.  All it takes is 3 easy steps:  Fill the sample stage;  Press START;  Measurement is displayed.
Uses: analysing fragrances, inverted sugar syrups including the determination of the rate of crystallization in honey.Purity, International Sugar Scale, Specific Rotation, and Concentration are automatically calculated from the measured refractive index and angle of rotation. Temperature is displayed constantly.

CM-In-Line Brix Monitor 800alpha


Used for continuously measuring concentration (BRIX) of various liquid samples.  The CM-800a In-Line Brix Monitor is Atago’s latest edition to the CM series. The accuracy is +-0.1% across the entire range of 0-80% Brix.

Auto Control : the recorder output (4 to 20mA) and the RS 232C output are incorporated to enable automatic control by interlinking with external equipment.

Automatic Temperature Compensation (ATC) allows the correct concentration (Brix) to be displayed and output, even if the temperature of the sample changes.

The sample temperature can be displayed while measuring Brix (%).

Safe for Clean-In-Place (CIP) processes (power source must be turned off). (Up to 130°C.)

Automatic Temperature Compensation (ATC) range of 5 to 100°C, allowing for high temperature in-line samples to be measured accurately.


  • Mixing diluting and concentrating processes at food manufacturing plants : fruit juice, soft drinks, alcoholic drinks, pickled liquid, etc
  • Fermenting processes : alcohol etc
  • Concentration shifts between different products
  • Concentration of waste liquids : waste liquid of sugar, alcohol, chemical etc
  • Concentration control of various solutions : liquid sugar, fructose, glucose, syrup, sugarcane/sugar beet, isopropyl alcohol etc.
