EON Replacement Breathalyser Sensor Module

From £109.00 Excl. VAT

SKU: N/A Category: Tag:

Buy a reusable sensor module for the AlcoDigital EON Breathalyzer and swap over the sensor module when your EON breathalyser is due for calibration.

Swap. Send. Simple!

The sensor module can be calibrated independently, without the breathalyser unit.  Send the sensor module to us; we’ll calibrate it and send it back to you – ready for next time. As long as you keep a spare calibrated sensor, you’ll never be without your EON breathalyser. This enhanced feature makes the EON totally unique – it is the only professional breathalyser in the world with EN approval to have a replaceable and reusable sensor which can be calibrated in this way.

The fuel cell sensor module has a life span of 3-5 years, provided it is professionally calibrated every 6 months.


Sensor Only – We send you the sensor and you fit it yourself

Fit and Replace – You send us your instrument, then we’ll change the sensor and run a simple service for you, including calibration, and then send it back to you.


How to send your breathalyser to us (Fit and Replace Service Only)

Once you have completed checkout, print a copy of your invoice and package your breathalyser up carefully (we’d suggest some bubble wrap and a padded envelope at a minimum; if you have the original packaging, better still). Include the invoice inside the package and make sure you clearly mark the outside of the packing with your return name and address.
