" Features

� Designed with a high– resolution thermal printer, which frequency response can reach to 150Hz, to print out ECG trace, annotation as well as related parameters for diagnostic reference. Roll recording paper is 63mm in width.
� Digital signal processor for effective inhibition of baseline drift, processing of AC filter, muscle filter and heart rate detecting, making sure a more stable and reliable signal processing.
� One-touch operation able to enhance efficiency and relieve operating strain. LCD display makes the working status clearly.
� Built-in RS232 interface, USB interface is optional.
� Concept of floating input circuit meets IEC safety standard.
� Supported by AC/ Rechargeable battery for continuous examination whenever necessary. For battery operation, ECG is equipped with a battery charger and a system for battery capacity management and protection. Rechargeable battery supporting more than 50 patient examinations.
� Modular design, can be connected to computer to storage ECG data, can be upgraded to three – channel. Better competitive price, so that the user' s investment is fully protected, while gradually improving medical standards.
