Question

We use the fish fatmeter to determine the fat content of sardine pilchards but we always have different results between the fish fatmeter (in example 6.85%) and the laboratory methods ( 3.85%) so we followed the instruction manual in order to verify the calibration with the low range pad (sardine 2 ---- 8%) after 8 readings we found 10.75 %. So what we can do to resolve the problem.

Answer

It seems that your Fatmeter is "Out of Calibration" specifications. If the Fatmeter is reading high on Check Pad, then it will read high on Fish (as you have indicated in your Fat results). So that we can assess the options available, please supply answers to the following Questions…

1. The name of your company
2. Where are you based
3. Contact telephone number, so that we can telephone you to discuss
4. The Serial Number of the Fatmeter (so that we can check which model you have, and the calibrations programmed in Fatmeter).
5. The Check Pad Readings on… Range 1 (reported as..8.0%), and Range 2 (Not reported).

There are TWO Options available...

1. Best Option… Return the Fatmeter to.. Distell, in Scotland, UK for… Service & Re-Calibration.
2. Depending on the model of Fatmeter… we may be able to supply a Re-Calibration by E-mail, with instructions on how to do this (latest models only).
