The Compensation Device
(Aquafauna Bio-Marine Refractometers)

Back Next

The refractive index of liquid differs with temperature. It is most desirable that measurement be made under constant temperature conditions of 20 degrees Celsius (68 degF). To achieve compensated readings of liquid samples which are not 20 degrees C, a fused bimetal compensator has been designed into the Aquafauna refractometer. Contained in the barrel, this device has excellent durability.Upon taking a sample under the daylight plate, the sample immediately adopts the temperature of the instrument. If measuring heated or refrigerated samples, allow the liquid to attain ambient temperature or wait 1 or 2 minutes after applying the sample to the prism. With the Aquafauna refractometer, it is possible to achieve accurate temperature compensated readings of liquid samples when the instrument is between the temperatures of 10 deg C and 30 deg C (50 deg F - 86 deg: F).
