Brand new in package Amoxtec Analox replacement sensor. This was just purchased 4/15/09 to replace the old sensor which was thought to be bad. Unfortunately the old one was not the problem. It was the unit itself which is not repairable according to company, and the sensor is not returnable. So this is for the brand new sensor and the old one which may or not still have life. $115 for both shipped in US. PM if interested or want photos.
