Rudolph Research J 357 Automatic Brix and Refractive Index Refractometer Fish Feeder the electrode should be calibrated

the electrode should be calibrated with 2 or 3 buffers or standards that bracket the expected sample range

One BRAND NEW ATAGO MASTER-HONEY (12%-30% Moisture scale) Hand held Refractometer in a cardboard/vinyl

The metal sides of the sample well allow the sample temperature to conform quickly and evenly to the prism temperature for accurate measurements

The HI 96811 digital refractometer eliminates the uncertainty associated with mechanical refractometers and is portable for measurements in the field
