Accessories

Office Style (parallel) Printer

These come in two main styles:

  1. Inkjet Printer
  2. Laser Printer

Desktop Laser Printer Sample Printout These office style printers have the following advantages:

  • Large paper size (American standard 8 1/2 x 11 inches or A4) required by cGLP/cGMP and often preferred by regulating bodies such as FDA
  • Multiple readings per page
  • Inexpensive replacement cost
  • Easy access to consumables

Strip Impact Printer

Receipt printers have the following advantages: Strip Impact Printout Sample

  • Small footprint
  • Designed for rough industrial environments
  • Does not use thermal paper
  • Industrial product with long model life, so that the printer is often available for many years
Refractometer with Strip Printer accessory

Barcode Reader

All Rudolph refractometers can be equipped with a barcode reader. The barcode reader has flexible programming enabling it to work with various barcode standards: Code 39, Codabar, Interleaved 2 of 5, UPC-A and others.
