Digital refractometers, RFM300-M

Supplier: Bellingham + Stanley
These refractometers bring with a line of high precision Peltier temperature controlled benchtop refractometers for demanding applications within the food, beverage, chemical and industrial industries.

  • Tactile chemical resistant keypad
  • Wide beam scan for non-homogenous samples
  • Three decimal place Brix precision* (6 d.p. RI)

Created specifically for use in harsh environments and builds upon legacy of quality instrumentation as well as incorporating wide beam optics, they are capable of measuring non-homogenous samples such as fruit juice with pulp, opaque chemical compounds and emulsions, that are normally difficult to read with optical refractometers or those digital refractometers that do not address the need to measure “difficult samples”.

The case is ergonomically designed, so that any spills are dealt with by the sloping shape of the case or by the PEEK spill barrier that surrounds the shallow, easy-clean stainless steel prism dish.

Certifications: US/EP/BP/JP compliant. Supports FDA regulation 21 CFR Part 11. PHR-MEAN & Coffee Solids Methods.

Ordering information: Can be fitted with optional extras - See under 'ACCESSORIES'. Validation documentation IQ/OQ/PQ available on request.

Delivery information: Supplied with power cable and multi-language manual.
