Buy Dexcom ONE transmitter

The Dexcom ONE Transmitter slots inside the Dexcom ONE sensor to send glucose readings wirelessly by Bluetooth to any compatible smartphone. 

Features

The Dexcom Transmitter has the ability to work as part of the Dexcom ONE system. It works to measure glucose just under the skin. The device sends real-time glucose readings to your smartphone every 5 minutes. Each transmitter will last for 3 months. 

Directions

The Dexcom ONE Transmitter easily snaps inside the sensor. Your Dexcom ONE will let you know when your transmitter will end. 

Dexcom provides a video showing you how to attach the transmitter. 

Warnings

This product is water resistant. Keep in mind that Bluetooth connections won’t work as well in water. If you are showering or swimming, try to keep your transmitter and smartphone in close range to one another.  

Age restrictions

This product is not suitable for children under 2 years old.

Pregnancy and breastfeeding

The Dexcom device has been approved to use during pregnancy.

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, you must ask your doctor or Chemist4U pharmacist for advice before using any new products.

Important information

This product contains the transmitter only; sensors must be purchased separately.

Please note that the manufacturer is unable to replace sensors that have been purchased for use on animals; this is because they are not licensed for this use.

Item needed to communicate with the sensor you wear. Works perfectly with Dexcom sensors.

Easy application and provides lots of useful daya for monitoring. Found it much better than the Libre. Also showed very similar readings to finger blood tests most of the time (sometimes slight variation on the fasting levels but so did both of my hands!).
