Why the sensor replacement is required
The KETOSCAN mini uses a very sensitive sensor that detects a very low concentration of millions of parts per million (ppm) to measure ketones with acetone. If you use sensors frequently, it will inevitably need to re-adjust accuracy due to contamination by various interfering substances in your breath, and this process is called calibration. Since calibration alone cannot fully revive the sensor, Ketoscan provides a sensor replacement service to replace and calibrate the sensor with a new one.


What is the process of sensor replacement service?

When is the sensor replacement required?

Sensor replacement service was straightforward easy to accomplish. I simply packed up my Ketomini in the original box it came in, and put it in a USPS box to be mailed to California. Hyunseok Oh was helpful in facilitating the fast turnaround of the meter service, total time was less than a week! The meter was as good as new, with a fresh 300 day countdown. An exceptional company and people to deal with!

Very pleased at how quickly this process went, despite the pandemic. I shipped them my Ketoscan unit and got an email a few days later that they received it. Another few days passed and servicing was done and I was informed it was being sent back to me with a tracking number. Great communication and quick turnaround! I love the idea the unit needs a sensor replacement every so often to insure its continued accuracy. One of the best purchases I’ve made as I continue to lose weight on keto.
