Source: extech.com (verified 2026-08-12). Extech's (Teledyne FLIR) official RF20 product page confirms it is a salinity refractometer, not a Brix meter: 0-100 ppt range, 1 ppt resolution, ±0.1% basic accuracy, and ATC between 10-30°C; the kit includes a case, calibration screwdriver, plastic pipette, calibration solution, and user guide with a 2-year warranty. Sample volume and prism material are not stated on the fetched page; brix_range_pct is not applicable to this salinity-only model and is left null.
