To order, click on the sensor finder link below. Select your model from the drop down list then click Find. The sensor you need will then be shown. Hover over the sensor and select "Buy" to add to your cart or "More Info" to see more detailed specifications.
If you do not see your model number in the sensor finder list, it is no longer available. Unfortunately, we have no way of obtaining transmitters for any clock models other than what are on the list.
