The TeleVue TV1x by DigiCare is an ultra small Bluetooth 3/5 Lead ECG transmitter. Small enough that it stays with your patient, the transmitter sends vitals via Bluetooth to a PC up to 300 feet away with the option to extend it to 1000 feet. Corresponding software automatically generates Excel and PDF reports and includes a 48 hour ECG recorder. The TV1x includes a rechargeable battery with up to 15 hours of charge and has a BPM range of 5-350 BPM for small or large animals.
