Bellingham + Stanley launch new high precision, touchscreen, Peltier temperature controlled refractometers

The RFM-T Series of high precision Peltier temperature controlled benchtop refractometers, featuring a wide measuring range up to 1.70 RI, precision to six decimal places RI (3 d.p. °Brix) and all-new 7” touchscreen user interface, are ideally suited for use in applications within the food, beverage, chemical, petrochemical, pharmaceutical, flavours and fragrance industries as well as in academic research.

There are currently five models within the RFM-T Series, each addressing a particular application or measurement performance need.  RFM900-T models cover the widest of measurement ranges and incorporate a Kalrez® prism gasket to protect the instrument from the harsh chemicals likely to be experienced at the upper end of its refractive index range.  

Additionally RFM900-T models have specific user Methods for the petrochemical industry including ASTM D 1218 (hydrocarbons) and ASTM D 2140 (carbon-type composition of electrical insulating oil) as well as PHR-MEAN Method used for statistical sampling in accordance with Pharmacopeia.  The RFM990-AUS32 model satisfies the requirements of diesel exhaust fluid (AdBlue®) manufacturers in accordance with ISO 22241.

RFM300-T models are tailored more towards the food and beverage sector and feature a very flat prism dish for easy cleaning between viscous samples as well as a number of user methods including coffee total solids and citric acid offsets.

The high definition touchscreen facilitates operation in many varied environments, and also serves as the centrepiece for the new software. Combined, the touchscreen and GUI help the operator quickly manoeuvre through the menus. On-screen graphical prompts support simple operation such as method loading, calibration and routine maintenance.
