The CT-1000 Cardiotachometer module provides a convenient and accurate measure of heart rate (HR) or beat-to-beat interval (R-R). Its many advanced features make it easy to set up and operate. The unit accepts either a low-level, direct-wired ECG input or a highlevel signal such as arterial blood pressure. The low-level input includes a medical-grade isolation amplifier for absolute safety and extra noise immunity.
