Description Parameters Resources

The portable ECG test and fixation board for mice eliminates the subcutaneous needle test for mouse ECG, reducing external stimulation damage to animals and saving time for experimental personnel.

1、The instrument is compact and small in size, using integrated anti-interference power supply, power AC 220V, built-in transformer in the chassis, no need to connect any transformer outside, the instrument does not need to connect any ground wire and ensure that the bioelectrical signal displayed is clear and accurate. Thus to ensure the anti-interference performance and accuracy of the machine. The leakage current of the patient is <3mA.

2、The instrument has 4 channels, all of which are multi-functional fully programmed isolated amplifiers. The amplifier of each channel can be used as bioelectric amplifier, blood pressure amplifier, bridge amplifier, and can also be used as a spirometer, thermometer, etc. And each channel has an independent hardware module, independent of each other, greatly increasing the anti-interference ability between channels, but also for the maintenance of the instrument has brought great convenience.

3、High precision 16-bit A/D conversion chip is adopted, and the maximum sampling rate of single channel hardware is 1000KHz. The minimum hardware sampling rate is 0.01Hz. The maximum sampling frequency is 100kHz for four-channel continuous sampling, and the sampling rate can be changed according to needs in the process of real-time sampling. Scanning speed: 0.05ms/div~3200s/div

4、Amplifier input resistance ≥100MΩ (double-ended input) \ 50MΩ (single-ended input), common-mode rejection ratio ≥100dB, noise ≤±1μV(RMS) or ≤±3μV (P-P), frequency response: DC~20kHz, input range: 5μV~500mV, spirit sensitivity :a) Bioelectric mode: 20uV/div~500mV/divb), blood pressure mode: 3.6-360(mmHg/div) 0.36-180(mmHg/div)(high sensitivity transducer)

5、Ac and DC have the same gain: range 500mv, 200mv, 100mv, 50mv, 20mv, 10mv, 5mv, 2mv, 1mv, 500uV, 200uV, 100uV, 50uV, 20uV, 10uV file adjustable; 10V electrical signal can be input directly and the amplifier is not saturated

6、Low-pass filter (hardware) : 0.3Hz, 3Hz, 10Hz, 30Hz, 100Hz, 500Hz, 1kHz, 3kHz, 10 kHz, OFF (20kHz). It has more than 5 filtering modes.

7、The main technical requirements of the photoelectric isolation program controlled stimulator are: single stimulus, series single stimulus, continuous single stimulus, double stimulus, series double stimulus, continuous double stimulus, timing stimulus, increasing intensity stimulus, increasing frequency stimulus, increasing wave width stimulus, strong interval recursive stimulus, automatic series double stimulus and other stimulus modes. Maximum load current: 100 mA, with positive current, negative current output mode, programmable output triangular wave, sine wave and other stimulus waves. Meet the national safety standards for experimental electricity consumption, will not cause electric shock due to misoperation. Output voltage <=50V, meet the national safety electricity standard (in addition, external synchronous stimulator can reach 120V)

8、Digital filtering mode: (1) High-pass, low-pass, band-pass, band-stop with adjustable filtering parameters. (2) zero-phase-shift digital filtering with adjustable order.

9、The hardware system includes ECG full lead lead card, each channel can be used for 12 kinds of lead electrocardiogram, lead switching mode can be programmed, lead mode a total of 12 kinds: Ⅰ, Ⅱ, Ⅲ, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6.

10.、The experimental environment data detection function is to measure and add the ambient temperature, atmospheric pressure and humidity of the current experiment in the experimental information as the environmental parameters of the instrument experiment.

11、The instrument panel is equipped with a 1-inch OLED LCD screen to display the current experimental environment information.

12、Each channel has the sensor automatic recognition function, and is displayed on the instrument panel LCD screen, and the software recognizes and prompts the user to automatically set the corresponding sensor parameters

13、Material: aluminum alloy +RF-4 gold plated Size:275X175mm

This parameter is the basic parameter of the equipment. Please contact us for specific parameters
