I have been working in partnership with Caption Data now for over 6 years. We have worked together to develop systems to suite the needs of our clients and our business. The key area of working with Caption Data is their after sales and support network which is key for our operatives out in the field.
Polygon were original users of CDL Hygronet systems, but now use the RDL//1000 system on a worldwide basis, including links to 3D Building Information Model graphical interfaces. The RDL//1000 now offers a Hygrostick compatible sensor.
