Introducing Distell Meters

Our Meters are pleased to say our products have been involved in a number of scientific studies.

We have three types of meters that are available:

Fish Fatmeter

For measuring the amount of fat in fish. Available in normal or small sensor sizes.

Meat Fatmeter

For measuring the amount of fat in minced meat product. Available in normal or small sensor sizes.

Fish Freshness Meter

or measuring the freshness of fish.

You can click on the meter images to find out more about each type of meter.

Our meters are all portable and battery powered, and you can expect to get at least a full day’s operation on a single charge. They are sealed to IP65 standard before leaving our workshops and are safe for use on food. The simple two-button interface means they are easy to use, and the robust casing ensures that they can withstand the harsh environments in which our customers operate.

How are they used?

Each of our meters are used in a similar way.

The normal operation of the meter is that, after the meter is switched on, the user will choose which calibration they want to work with (and we’ll explain a bit more about that below). Once that’s done then the meter goes straight into measuring mode and the user can start recording readings on actual fish or meat product. From switch on to getting results takes less than thirty seconds (Freshness Meter) or a few minutes (Fatmeter).

Readings are taken in groups, for averaging purposes. Normally the Fatmeter takes 8 readings in a group and the Freshness Meter takes 3, but this can be configured by the user. Each individual reading is stored in the meter, along with the average for the set of readings and the date and time the reading was taken. Once a group of readings has been taken then the user can move on to the next sample just by pressing a button on the meter. This helps to keep the measuring process flowing quickly.


For each meter, whether it is a Fatmeter or a Freshness Meter, the internal sensor will give a different response for different types of fish or meat. For example, a section of tuna with 10% fat will produce a different sensor response to a herring with 10% fat. To get valid data from the meter, therefore, we need a method of translating the different sensor response into a meaningful, accurate reading. This method is called a ‘calibration’, and since different species and types of meat and fish respond differently we have a wide range of different calibrations to cover the different samples. We have over one hundred calibrations available across all our meter types.

It is important to understand the principle of a meter calibration, and you can read more about them here.

Each meter can hold many different calibrations, and the purchase price of a Fatmeter includes four calibrations of your choice. The Freshness Meter has a standard set of calibrations. Meters can also have custom calibrations created, and we provide the tools to enable you to do this.

Data Management

As more samples are measured, each set of data is stored in the meter. To get the data out of the meter for analysis you use our Data Management System, or DMS. The DMS is supplied with every meter. To copy the data from the meter to the DMS you follow these simple steps:

  • Start the DMS software,
  • Connect the meter to the computer using the supplied USB cable,
  • Tell the DMS to receive data, and
  • Tell the meter to download its data to the DMS.

Once the data is in the DMS you can browse through the readings, make notes and print reports. You can also export the data for use in a spreadsheet, database or other analysis tool.

Advanced Usage

The DMS can also create custom calibrations based on a combination of meter readings and laboratory analysis. This might be of interest if you are working with a sample that has no existing calibration, or if you are carrying out some specific research with the meter. If this sounds like it might be useful to you, please contact us and we can discuss your requirements in detail.

Try or Buy

If you would like to go ahead and purchase a meter then you can do so through our worldwide distributor network, or just contact us directly if there is no distributor in your area.

We recognise that many people prefer to evaluate our meters first, so we have a range of short term rental packages that allow you to get hands-on experience with Distell meters for a minimal cost. You may prefer to purchase a meter in instalments over a longer period, in which case one of our long-term rental packages will be an ideal way forward.
