Measure Fish Fat & Fish Freshness with one device!
Yamato Scale's Fish Analyzer is the world's only hand held device that can measure both fish fat & fish freshness. Accurate results in less than 4 seconds, non-destructive and easy carry hand held device.
Currently supports 20 fish specie with the option of making a custom calibration for your specific fish.
It's widely used in Japan's fish markets, grocery stores, Universities and private laboratories. Now available for purchase worldwide!
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
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.
Easy To Use & Rugged
Fast, Easy & Accurate results in 4 seconds! Power it on, select the fish, take the measurements and get your results. It's that easy and quick!
Ease of Use:
No special training or prior knowledge needed.
Bluetooth wireless connection to PC. (coming soon)
Big LCD display & easy to navigate menu options.
Rugged & Ready for Outdoor!
Water proof to IP65 standards for wet condition use.
Durable & sturdy casing for rugged outdoor use.
3 CCC battery life up to 15,000 measurements.
Results in seconds & Non-destructive
Take few measurements on the fish and get the fish fat percentage & fish freshness grading. Accurate results in seconds.
Yamato's Fish Analyzer was designed to be used on live fish since it does no harm. Once you're done taking the measurements, reuse the fish any way you like.
Great for markets or grocery quality control, to monitor growth for research or to determine if the fish was previously been frozen. May use cases!
Limitations
No device is perfect, this goes for Yamato's Fish Analyzer as well. We are 100% upfront with what's capable with this device.
Minimum fish size needed: fillet (body) portion must be at least 0.4 inch (1cm) thick and at least 4 inches (10cm) long.
Can NOT measure frozen fish, it must be completely thawed or defrosted.
No Bluetooth wireless connection feature yet. It's coming soon.

Yamato Scale's Fish Analyzer supports Custom Calibration, contact us for more details.
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.
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.
