    Polar Heart Rate Monitor

    $104.65
    The PHRMN-100 is a PolarTM Heart Rate Monitor fitted with a connector that makes it compatible with the iWorx NI ELVIS Bioinstrumentation Expansion Board (IX-ELVIS) as well as the NI myDAQ.
    MFR Part #: PHRMN-100
     

    With the PHRMN-100, the voltage changes that take place during an electrocardiogram are picked up by two electrodes on the inside of a band around the subject's chest. These voltages are transformed into simple coded signals by the transmitter connected to the electrodes. The transmitter broadcasts the coded signals to a receiver that is connected to the data recording system. Since the frequency of the coded signals from the transmitter correspond to the heart rate of the subject, a periodic rate function in the recording software is used to convert the frequency of the coded signals into a display of the subject's heart rate. This technology enables relatively noise-free heart rate determination to be made from resting or exercising subjects.

     

    Specifications:

    Water Resistance: Water resistant up to 100 feet/30 meters
    Battery Type: CR 2025
    Battery Life: Average 2 years (1h/day, 7 days/week)



    Measurement Instructions:
    1. Detach the WearLinkâ„¢ coded transmitter from the sensor band.

    2. Moisten the electrode areas of the sensor band under warm running water. Make sure these areas are well moistened.

    3. Adjust the length of the sensor band to fit snugly and comfortably around the chest of the subject. Secure the sensor band around the subject’s chest so that the electrodes are just below the chest muscles.

    4. Attach the transmitter to the sensor. The PolarTM logo should be upright. Adjust the sensor band so that the transmitter is in the center of the chest.

    5. Check that the wet electrode areas of the sensor band are positioned firmly against the subject’s skin.

    6. Set up the receiver so that it is no more than 1 meter away from the transmitter. Use the supplied extension cable if necessary.

    7. Install the IX-ELVIS board into the National Instrument ELVIS platform or the IX-myDAQ board onto the NI myDAQ. If using ELVIS, connect the ELVIS power supply to the ELVIS unit and connect it to the computer via a USB cable. Ensure both of the power switches are in the “on” position. For the myDAQ, connect it to the computer using the USB cable.

    8. Connect the MINI DIN7 connector of the PHRM-100 to either CH1 or CH2 of either the IX-ELVIS or IX-myDAQ board.
    9. Open the recording software, select the channel that the PHRM-100 is connected to and ensure the range is set to +/-5V.

    10. Press record. Once you see the heart signal on the waveform chart, press the Calibrate button to automatically set the threshold.

    *Note:
    The signal may be inverted if the IX-MYDAQ is used.
