A clamp assembly for connecting at least two downhole tools to a section of tubing, the clamp assembly having a first clamp part and a second clamp part. The first and second clamp parts having ends, sides, and inner and outer surfaces extending between the sides. A first clamp part end has at least two mechanical connections defining ports for receiving and securing downhole tools, wherein one of the ports is a read-out port. A hinge assembly connects the first clamp part to the second clamp part and is configured to permit the first clamp part and the second clamp part to be moved to a closed position and an open position. A fastener connects clamp sides when the first clamp part and the second clamp part are in the closed position. When in a closed position, the first and second inner clamp surfaces grip the exterior surface of the tubing.
