RR1090

$189.00

The RR1090 is a multi-scale, digital, differential refractometer with Bluetooth output and cloud spreadsheet logging capabilities. The raw refractive index of an aqueous or semi-aqueous sample, such as honey, is measured using our proprietary FresnelZoom algorithm and technology. The sample well temperature is monitored using a high precision thermocouple while a multitude of derived scales are provided from the raw index.

Measure and track Brix, specific gravity, coffee total dissolved solids (TDS), water in honey. Track salt-water aquarium salinity according to refractive index data from Scripps*. Measure %w/w for methanol, propylene glycol, ethylene glycol, glycerol or ethanol.

Use the RRTool mobile app to log measurements in real-time to your private cloud spreadsheet, to enable extra device features (ATC, QRcode generation) or to upgrade the firmware on the device.

 

Crafted and assembled in Livermore, California, from  and imported components.
