Please note to check if your unit uses a pressure or non-pressure sensor before placing your order. You can check which type of sensor you need here.


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. You can book your unit in for calibration on Caltrace
