How does it work?

Yamato Scale's Fish Analyzer measures electrical impedance of the fish to provide fish fat percentage & fish freshness. Fish freshness is graded on 5 levels from A, A', B, C and D.  

The device applies a small multi-frequency electrical current to the fish to measure the impedance (resistance). The impedance measurement tells the device how much water content is in the fish and from its unique algorithm, outputs the result of the fish fat percentage and fish freshness.

Fish Freshness Grading Scale

Yamato Scale Fish Analyzer Freshness Grading Scale
How to read the chart:
Status of Fish: Grading from A/A', B, C and to D.

A/A' = very fresh
B = Fresh
C & D = Edible but must be cooked.

Fish Analyzer FAQ's
Assurant Innovations FAQ
Yamato's Fish Analyzer uses multi frequency (low & high) bands to measure fish fat content.

The low frequency band detects electricity flow outside/around the fish cells. The high frequency band detects electricity flow into/through the fish cells. Using these low and high frequency bands, Yamato's Fish Analyzer calculates the impedance (resistance) of the frequencies to provide the fish fat percentage and the fish freshness grades.

Yamato's Fish Analyzer uses multi band frequency method to achieve high accuracy of the results.
The minimum fish length excluding head and tail is 4 inches (10 mm) and thickness 0.4 inch (10 mm) to measure the fish accurately.
No it can not. The fish needs to be properly defrosted or thawed.
Yes it can. Yamato's Fish Analyzer is non-destructive measurement tool so you can measure the same sample many times as needed without affecting the quality of the fish.
Yes it can. Since this meter is non-invasive and non-destructive, it's harmless to use on live fish.

You can use it measure and monitor as the fish grows as it responds to certain diets and environment.
