Ketone Breath Monitor -KT004W

How to get accurate readings with our Keto Breath Meter? 1. In order to get accurate ketone readings, please exhaust the residuals completely with the ketone meter before your first use by running the keto breath tester 3 times without blowing, because each ketone breath analyzer was tested during the production before shipping to warehouse, there maybe residuals; if you want to test another person consequently after your testing, please also kindly exhaust your previous residuals 2. Please blow immediately within first 5 seconds when displaying BLOW on the ketosis tester if you finish the residuals exhaustion step, because the ketone breath tester starts analyzing the breath right after the first 5 seconds   Breath ketone meter saves you from finger pricks, and the device can be used repeatedly by replacing the mouthpiece; the ketone breath testing is a far more accurate method than urine strips testing, also more convenient because you only need to breathe with the ketone monitor
