The Kestrel USB data transfer cable 0785 allows wired communication between any model in the Kestrel 5000 Series and Windows/Mac computers with a USB port. The cable can be used with Kestrel LiNK software to install firmware updates and upload logged data from a 5000 Series meter. Communication between cable and meter is optical so does not compromise the Kestrel water-tight seal. Cable length is 3 ft ( 915 mm) and data transfer speeds are up to 230 Kbps. The cable weighs just 2 oz (56 gm) so is convenient to carry around.
