Bellingham + Stanley Digital Refractometer RFM330-T with Peltier Temperature Control and Touchscreen
RFM330-T digital refractometer with 2-decimal place / 0-100 Brix (1.58 RI) touchscreen input and Peltier temperature control. Perfect for measurement and control in demanding food, beverage, chemical and industrial applications.Advantages of the digital refractometer RFM330-T at a glance:
- High definition touchscreen display
- Flat prism surface for easy-cleaning
- Wide beam scan for non-homogenous samples
- Supports FDA regulation 21 CFR Part 11
RFM300-T Series refractometers are designed specifically for use in harsh environments and builds upon Bellingham + Stanley’s 100 year legacy of quality instrumentation. Incorporating wide beam optics, RFM300-T Series 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.
Inherent to the design is the high definition, capacitive touch-screen display that not only facilitates operation in factory environments, even when operated whilst wearing gloves, but also serves as the centrepiece for the software. Combined, the touchscreen and GUI help the operator quickly manoeuvre through the user and configuration menus. On-screen graphical prompts support simple operation such as method loading, calibration and routine maintenance.
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.
Measurements with the RFM300-T are made through a familiar measuring mode or by way of a simple Methods system with one-touch configuration of scale, temperature and data storage, with up to 8000 results being saved alongside pre-set limits that can be used as an audit tool.
