3. REFRACTOMETRO DIGITAL. RFM 340. Automatic Refractometer

Perfecto estado. Aproveche. Excelente precio. 

The RFM 340 automatic digital refractometer offer the latest in simplicity of operation, accuracy, reliable performance, versatility and durability.
The instrument encompasses the following scales :
  • sugar % (Brix)
  • refractive index
  • 5 user defined scales where is possible create personalised scales or insert the following scales:
  • zeiss
  • oechsle
  • butyro
  • 42% fructose
  • 55% fructose
  • 90% fructose
  • baumé
  • sodium chloride
Each scale has varying degrees of precision, with a maximum of +/- 0,03% for the scale Brix, e +/- 0,00004 for refractive index.
Temperature compensation available on all scales from 5°C to 60°C.
The instruments have no moving parts - solid state technology.
External power supply unit for safety in location of instrument and prevention of heat built-up in instrument.
Border line quality, is an arbitrary number used to define the "worth" of a reading. This indicates to the user how well defined the borderline is and hence the reliability of the reading
Large reading display for indication of sample measurement
Artificial sapphire prism in stainless steel sample dish.
Wide range of accessories as "flow cells", waterbaths, printers and computer can be connected to the instrument.
The sample presser will improve measurement accuracy and repeatability by:
  1. Forcing the sample into intimate contact with the prism surface. This is particularly important with viscous, high concentration samples.
  2. Providing an "enclosed" environment for the sample so minimising contact with the air and limiting evaporation.
  3. Preventing strong ambient light from affecting the reading quality.
Password system at two levels allowing only authorised staff to enter the instrument menu.
A delay before reading can be utilised for the stabilisation of particular samples.
