This is a sensor for the ETC controller. Designed exclusively for ETC these NTC type sensors are made from 304 stainless steel. They come with 2 meter teflon coated steel braided sensor cable with quick disconnects at both ends. 35mm length measured from the flange face.
Please note; these sensors have been designed exclusively for our ETC controller and will NOT give accurate measurement for the common STC-1000 controller used by home brewers.
