Replacement Recording Paper in Rolls for the older style (now obsolete) Analagraph® Chart Recorder. For charting patient progress and providing a visual aid for both doctor and patient, we now offer the Wireless Analagraph® to replace the old chart recorder. The Analagraph® is used in conjunction with the ETS-9A to transmit your readings to your PC wirelessly. *Please note the graph paper is not required with the new Wireless Analagraph® and is only compatible with the older style recorder.
