Description

Bellingham + Stanley Digital Refractometer RFM330-M with Peltier Temperature Control and Keypad

RFM330-M digital refractometer with 2-decimal / 0-100 Brix (1.58 RI) scales and Peltier control. Perfect for measurement and control in demanding food, beverage, chemical and industrial applications.
 

Advantages of the digital refractometer RFM330-M at a glance:


RFM330-M refractometers are designed specifically for use in harsh environments and have been built using Bellingham + Stanley’s 100 year experience of quality instrumentation. Incorporating wide beam optics, RFM330-M refractometers 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 instrument’s 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.

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.

The RFM330-M’s large, clear buttons and 4” high resolution screen help facilitate operation in factory environments, and combined with our latest GUI, help the operator quickly manoeuvre through the menus. On-screen prompts support simple operation such as Method loading, calibration and routine maintenance guiding even the newest member of your staff.

RFID swipe technology comes as standard, providing clearance and a log of operator and configuration functions; especially useful when being used in FDA regulated environments operating in accordance with 21 CFR Part 11, or where good practice is adopted, e.g. as part of HACCP.
