NEW for 2017, the RFM300-M brings the popular 300+ refractometer up-to-date with a line of high precision Peltier temperature controlled benchtop refractometers. With wide beam optics and a durable membrane touch-button interface with 4" high-res display, the RFM300-M Series is ideally suited for use in demanding applications within the food, beverage, chemical and industrial industries.
Designed for use in harsh environments and built upon Bellingham + Stanley's 100 year legacy of quality instrumentation. Incorporating wide beam optics, RFM300-M Series refractometers are capable of measuring non-homogenous samples including 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 instrument's new 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.
A single large fan helps to regulate temperature as part of the Peltier control system. Operating at low speeds creates less noise whilst still offering the same excellent temperature control you'd expect to find in a Bellingham + Stanley refractometer. Positioned at the base of the unit, the RFM300-M's fan is designed to be protected from harsh environments, whilst still being easily accessible for maintenance.
Durable display & RFID technology
Whilst we believe that the touchscreen technology seen on our RFM-T Series refractometers is a class-leading interface, sometimes our customers want something a little more... tactile. That's where the RFM300-M comes in.
With a durable membrane made from chemical and scratch resistant polyester, the RFM300-M offers a more tactile approach, allowing users to navigate menus at the touch of a button.
