Data Harvest Wireless Ekg/Ecg Sensor 1158

A new Smart Wireless range of science sensors providing the same pre-calibrated accuracy and reliability but with the addition of Bluetooth as well as USB connectivity and can wirelessly connect to mobile devices e.g. tablets and mobile phones as well as desktop computers such as PC's, Apple Mac's and Chrome-books, giving students the ability to run experiments independently, without being tethered to a traditional Data Logger. The range comes with a huge battery life, can be used as a Data Logger in it's own right and can mix and match with existing SmartQ Sensors and Data Loggers!  The E.C.G. (Electro-Cardio-Gram) sensor monitors the electrical energy produced during a heartbeat. The change in electrical energy is detected by two leads and referenced to a ground signal. The changes in energy are displayed as a waveform. The sensor is supplied with a pack of 100 E.C.G. electrode patches for attaching to the test subject's skin. The electrode patches are disposable silver/silver chloride hypoallergenic gel on a foil backing. Replacement packs of patches are available.
