Where to buy replacement sensors?

For the Alcosense Zenith only.

You can purchase it through our online store via the link below:

Please note to check if your unit uses a pressure or non-pressure sensor before placing your order.
If your unit has a pressure sensor, it will need to be returned ONCE to be calibrated and change of parts to fit the non-pressure sensor. This will cost $60 ( inclusive of calibration cost + shipping charges)
