HE-12E Portable 12 Channel Digital Electrocardiogram ECG Machine

Introduction
The device is an electrocardiograph which can collect 12-lead ECG signal simultaneously and print ECG waveform with thermal printing system. It features in, recording and displaying ECG waveform in auto / manual mode; measuring, analyzing and diagnosing ECG waveform parameters automatically; prompting for "Lead off" and "Lack of paper"; optional interface language (Chinese / English, etc.); built-in lithium battery, AC / DC; selecting rhythm lead freely to observe abnormal heart rhythm; case database management.
 
Functions
1. Adopt 10.1'' high-resolution color LCD, operate by full-touch screen and function bu ttons, convenient to use.
2. Sync collection for 12-lead ECG, support 12-lead and Cabrera-lead waveform display. Get high-quality ECG waveform via power frequency filter (50 / 60 Hz), baseline filter and EMG filter (25 / 35 Hz) of ECG signal.
3. Display 3 / 6 / 12 - lead ECG waveform, HR value, print mode, sensitivity, paper speed, filter state, clock, battery power, background grid, measured parameter and interpretation, etc. on one screen, and with prompt functions for lead - off, overload and system working state.
4. Power supply: AC / DC (which can adapt AC 50 / 60Hz), with built-in rechargeable lithium battery, charging circuit, perfect over-current and over-voltage protection circuit.
5. In optimal DC state, up to 10-hour standby time, continuous print for more than 3-hour, which meets the requirements of visiting a patient at home and body examination.
6. Built-in thermal printer, support multiple printing modes and formats, such as, auto M × N, M × N + 1, M × N + 2, rhythm M line and manual, etc. The contents including time, paper speed, sensitivity, calibration signal, lead name, filter state and patient information can be printed. The waveform length printed, measurement parameter output, diagnosis conclusion, superimposed QRS waveform, histogram, trend chart and interval list, etc. can be set. With the print functions (timing print and auto-print for arrhythmia, etc.), which meet different requirements.
7. With the functions of auto-measurement and auto-interpretation for routine ECG parameters, provide measured results and auto-diagnosis conclusions for HR, PR interval, P Duration, QRS Duration, QT / QTc interval, P / QRS / T Axis, R (V5), S (V1), R (V5) + S (V1) amplitude, etc. which reduces the doctor's burden.
8. Built-in memory stores 4000 cases (data saving time: 10 s) at least, convenient for case review and statistic.
9. Historical cases can be reviewed, inquired, modified, transmitted, printed, lead corrected, the cases can also be exported to other electronic file formats (dat, pdf, xml, bmp, jpeg, etc.)
10. Chinese / English operating interface, the report in corresponding language can be printed; built-in virtual keyboard, support Chinese / English input method.
11. Support external USB standard keyboard, mouse, scanner and printer.

Customer Evaluation

 

1.What is time of delivery?
Since our products are produced according to each specific order, the delivery period will be 15days after confirmation of order. If it is small or sample order, please do check with us about whether we have ready goods in stock to make delivery as soon as possible.
 
2.What about quality assurance?
We offer one year warranty period beginning from the time of shipment for medical equipment, Per minor problems, we can provide free spare parts for replacements, Per serious problems, we can make replacement of free charge. But if the machine is damaged due to rough handling during the transportation, we are free of any responsibility, but we will still provide help to the buyer issue claims against the shipping company or insurance company, thus all the spare parts or expenses should be borne by buyer.
 
3.What about the price level?
We are confident that our prices are competitive compared with those at the same quality level, since we have stayed in this filed more than 20 years. And we always adhere to the principle of provide top quality products with competitive prices. We have already established our good fame in many countries, especially in Africa, Middle East, European, Asia and South American through year after year efforts.
 
4.Why we find some prices are very high compared with some other supplier, and from the picture or it's model number, all looks the same?
As China is still a developing country, there are only a few products with patent rights, and copy products I spread very fast in the market. Of course, the prices of those copy products with cheap material and less quality control are relatively cheaper .
 
5.What is payment terms?
T/T in advance, L/C, Western Union, PayPal, MoneyGram.
