Using breath acetone sample, breath ketone metres are used to estimate ketone levels.

Estimates real-time blood ketone levels using a 10-second breath sample.
This ketone breath metre is great for detecting diet-induced ketosis during a weight-loss or training programme.

A ketone breathalyser can be used over and over again.

To assess your ketone levels, you can use a ketone breath analyser instead of taking finger prick blood samples.

All ketone breath metres work by sensing acetone body levels in the breath and electronically converting them to the predicted blood ketone levels.

If you don't want to have to take a finger prick test on your blood, this is the best ketone metre in the UK.

While a breath ketone metre will never be as exact as direct blood ketone tests, when compared to blood ketone metres, this ketone metre gets pretty near, with accuracy of +/- 0.01 g/l.

Two AA batteries are required for the ketone metre (not supplied)

When sampling, users must avoid harming the sensor with alcohol or tar.

Sequential testing is bound to have some variation. Readings can be influenced by odours, perfumes, and volatile esters.

Every unit comes with an instruction on how to get correct readings.
