Question

Does temperature affect the performance or results achieved using the Fatmeter?

Answer

Provided that the Fish or Fish Fillets being measured are not frozen, and no ice crystals present in the sample, temperature should have no significant effect. Where the Fish or Fish Fillets are frozen, or contain ice crystals, the Fatmeter will tend to over-read the Fat Content level... this is due to the Microwave system being unable to measure the water in the frozen state, thus interpreting a lower quantity of water in the fish... than is actually the case.

• We have found that Fish and Fish Fillets down to –2°C normally do not contain ice crystals... and can be measured as normal.
• We have also found that Fish or Fish Fillets, stored at or above 10°C, can suffer moisture loss, and create a variance from the Fatmeters' Natural Fish Calibration.
