Digital Refractometer with Peltier temperature control and touchscreen, SKU: 19-40, RFM340-T-  Bellingham+Stanley UK

The RFM340-T combines high-precision peltier-temperature control and a dynamic touchscreen in one product, which is ideally suited for demanding applications in the food, beverage & chemical industries.

Advantages of the digital refractometer RFM340-T at a glance:

• 7" high-resolution HD touchscreen display
• Flat prism surface for easy cleaning
• Wide beam scan for non-homogeneous samples
• Brix precision to three decimal places* (6 d.p. RI)
• US/EP/BP/JP compliant
• Supports FDA Regulation 21 CFR Part 11
• PHR-MEAN methods
• USB & Ethernet connections

Bellingham + Stanley has been manufacturing refractometers for over a century. This vast experience has been incorporated into the development of the latest generation of instruments, resulting in the most advanced product range to date.

The RFM300-T is the latest in a series of refractometers designed specifically for use in harsh environments. With wide beam optics and one of the flattest prism platforms on the market, our RFM300-T refractometers are capable of measuring non-homogeneous samples such as fruit juices with pulp, chemical compounds and emulsions.

The ABS housing of the new device is ergonomically designed so that liquids spilled next to it can run off via the slopes or be collected by the PEEK drip skirt, which encloses the easy-to-clean stainless steel prism tray.

An inherent part of the modern design is the new high-resolution capacitive touchscreen, which not only allows use in factory environments and operation with gloves, but is also the centerpiece of the new software. This helps the user to quickly maneuver through the user and configuration menus.

SMART temperature stability, RFID user activation and application-specific, pre-programmed methods simplify routine analysis in the pharmaceutical and petrochemical industries. The included PC software allows the device to be controlled via an Ethernet connection, enabling remote technical support and training.
