            Difference between Pressure and Non Pressure sensor of AlcoSense Zenith?

            There is no difference in function or accuracy. The only difference is the type of sensor to replace to calibrate the unit.

            Pressure - with red, black and white wires.

            Non-pressure - without wires.


            The non-pressure sensor wont work in the unit that requires a pressure sensor, and vice versa. You will have  to remove the sensor (the rectangular board you'll first see) to see this. 


             Please check the image below before purchasing. Should you still remain unsure which sensor you own, take a picture and e-mail it to us at support@andatech.com.au
