Ketoscan Lite is easy to use and is an ideal way to test for ketones when following a ketogenic diet for weight loss, fitness and wellness or medical treatment.

The accurate electrochemical cartridge inside KETOSCAN Lite measures the concentration of ketones (acetone) in your exhaled breath, indicating when your body is burning fat and enabling you to perfect your food and exercise plan.

Readings are given in PPM (parts per million) and are displayed clearly on the LED display.

How to interpret KETOSCAN Lite results

Your ketone reading will be displayed in PPM, up to 40PPM. This reading gives you an indication of your level of ketosis. Below is a guide to interpret results:

  • 2 – 3 – body fat is burning at an average rate of 2g per hour.
  • 4 – 9 – body fat is burning at an average rate of 5g per hour.
  • 10 – 40 – body fat is burning at an average rate of 10g per hour (do not maintain this level of ketosis for extended periods of time)

Ketoscan cartridge change

To maintain high levels of accuracy, KETOSCAN Lite requires a new electrochemical cartridge every 300 tests. Please note that if a new cartridge is not fitted before 300 tests your device will stop working.

Great Device!!!

For what I could see, it works! I measured my ketone level before starting a 48-hour water fast, during, and after. There is no doubts that the device was accurate on its readings.

Also, both my external and internal boxes arrived partly damaged, due to DHL forcing it through the letterbox. Despite being DHL's fault, Ketoscan took responsibility for it and immediately returned my P&P costs - that tells me a lot about customer service.

Very satisfied customer!
