Robertshaw 9025I Remote Outdoor Sensor

hi I'm Terry with lacrosse technology and we're looking at a number of the different sensors that are used in our cross technology weather instruments and clocks without door temperature reasonable looking at them is that there are enough differences that it is important to know what we're looking at as well as how they mount some of the sensors like this TX 60 to our solar sensors you cannot change the batteries in this but they are recharged in the solar unit in use you push the button and the sensor comes alive the TX 29 UD th is similar and that it does have a display with the outdoor temperature and humidity this is a battery operated sensor these two sensors look the same and aren't the same one is a TX 29 and the other is a TX 37 and the only actual way to tell the difference is by the model number which is right below made in China and above the blank line on each this is a TX 6
