SCHMIDT+HAENSCH DUR-W2, High accurate digital refractometer

High accurate digital refractometer to measure refractive index of liquid media. Single and continuous measurements possible, different sample doors optional. Extensive, modular software allows versatile but easy use, up to 30 user defined scales programmable. Purity calculation by combination of DUR measuring head with S+H polarimeter.

Measurement Range RI  Up to 1.53200 Up to 1.70000 Up to 1.70000 
Resolution +0.00001 +0.00002 +0.00002 
Working Temperature +40 C +100 C +40 C 
  • Separate water proof measuring unit made of stainless steel allows analysis of liquid samples without any risk of damage to the electronic unit due to spillage
  • Single or continuous measurements possible by using the measuring unit either in the horizontal or vertical position. Unique feature from Schmidt + Haensch that allows the same measuring unit to be used for dual applications
  • 8-line graphic LCD display to read out Date, ID No., RI value and Temperature
  • Thermostatable sapphire prism
  • 30 free user-definable scales

The use of refractometers is universal. Very common applications are:

  • Determination of refractive index
  • Determination of dry substance concentration
  • Qualitative analysis
  • Identification of products
  • Determination of purity (the refractometer detects very clearly contaminations of a product, e.g. an addition of 1% electrolyte to water modifies RI by
  • Quantitative analysis of two-component mixtures, e.g. solutions of sugar, salt, etc. in water.
