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 Analyzer FAQ

How do I purchase or buy the Fish Analyzer?
Please call us at: 1.800.295.6134 or email at: info@assurantinnovations.com
We do not provide pricing information on our websites.
What's the minimum fish size (length) and thickness the Fish Analyzer needs to measure accurately?
For the Fish Analyzer, the minimum fish length excluding head and tail is 4 inches (10 cm) and thickness of 0.4 inch (10 mm) is needed to measure the fish freshness and fish fat (lipid) accurately.
What can the Fish Analyzer be used for?
The Fish Analyzer was developed to measure freshness of fish and fish fat (lipid) accurately, on the spot and instantly. These devices has been used as fish research, fish aquaculture (fish growers) and fresh fish markets.

The Fish Analyzer can be used for:
- estimate the freshness and quality of fish on the spot to ensure supplier compliance.
- grade fish freshness scale
- determine if a fish has been previously frozen or irradiated
- estimate shelf life in fish markets and stores
- check the age of fish during fishing and angling competitions
How does Fish Analyzer work to measure fish fat (lipid) and fish freshness?
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 a multi band frequency method to achieve high accuracy of the results.
Can the fish being measured be used after testing with the Fish Analyzer?
Yes it can. The Fish Analyzer is non-destructive measurement device and tool so it does no damage to the fish. You can measure the fish many times as needed without affecting the quality of the fish. After measurement, you can sell it or cook to eat safely.
Can the Fish Analyzer measure on live fish?
Yes it can. The Fish Analyzer can be used to measure on live fish as long as you're able hold the fish steady for the sensors to take measurements. Since the Fish Analyzer is non-invasive and non-destructive device, it's harmless to use on live fish.

It's a great way to monitor the fish health and growth as it responds to certain diets and environmental conditions.
Can the Fish Analyzer measure frozen fish?
No it can not. The Fish Analyzer can not measure fish freshness while the fish is still frozen. The fish must to properly defrosted or thawed.
What are the limitations of the Fish Analyzer?
The Fish Analyzer has the following limitations:
- it can not measure fish that currently frozen, the fish must be thawed or defrosted.
- Minimum fish body size needs to at least 0.4 inch (1cm) thick and at least 4 inches (10cm) long.
- No way to transfer data to the PC electronically. No Bluetooth wireless connection feature yet, it's coming soon. The measurement result must be manually written down.
