Digital refractometer
Six decimal place Refractive Index precision digital refractometer with peltier temperature control. Featuring a wide measuring range up to 1.70 RI and new 7” touchscreen user interface, are ideally suited for use in applications within the chemical, petrochemical, pharmaceutical, flavours and fragrance industries as well as in academic research.
The RFM900-T series of refractometers combine the latest optoelectronic principles with durability and ease of use. RFM900-T refractometers feature RFID (Radio Frequency Identification) that allows users to identify themselves by simply swiping a tag across the top of the instrument to enable measurement and, in certain cases, access to the configuration menu.
A low-profile sample dish and non-contact presser makes sample application and cleaning easy. Readings can be taken automatically on the replacement of the presser, and over 8000 stored results can be easily viewed in tabular form on the instrument display. Peltier temperature control and intelligent temperature management ensures readings are only taken when the sample and refractometer temperatures are both stable.
