Refractometer Calibration Oils
Calibration Oils are one of the most commonly used materials for calibrating refractometers as they have good traceability, particularly to NIST. Having a high temperature co-efficient, Calibration Oils are best used where strict temperature control is adopted either by Peltier or external waterbath between 10 and 75 °C as well as with refractometers operating at ambient by making use of supplied tables or an RI/°C Temperature Calculator as long as the prism temperature is reliably known.
