FL40 Handheld ECG Monitor , color screen , real time PC view

$199.95 199.95

The FL40 is an Ultra-Portable ECG Unit with a 2.8" color TFT screen. It is ideal for EMS/Rescue, physicians, home care, and patient use. 1-lead 30 second ECG Strips and results are displayed on the sharp TFT screen, stored on internal storage, or transferred to a PC for archiving or printing. Software is included for transferring data via PC, USB Cable, or 3-lead ECG cable.

The FL40's 0.5 to 75 hertz frequency response provides optimal signal quality. Grid marks are provided at 5mm spacing. The unit can be configured to store 30 second strips or be put in a continuous mode for extended monitoring.

Patients may hold the unit's electrodes between both hands (Lead I), while holding the unit against the left leg with the right hand (Lead II), or while holding the unit against the chest with the right hand (chest lead). Dry skin may cause high impedance, resulting in poor signal quality. Applying water or gel to the skin may improve impedance and ECG signal quality.

For better signal quality, the optional limb clips or snap-ecg electrode cable can be used. The limb clips can be clipped against the patient's wrists or leg. Gentle pressure should be applied to the limp clips to reduce artifacts and noise. The limb clips are especially useful on geriatric patients which may have thin skin that can be easily damaged with electrode use. For the best signal quality and minimal amount of noise on the ECG waveform, use the 3-lead cable with electrodes applied.

The user should always relax when taking measurements. Muscle action may cause noise to appear on the ECG signal.

The unit will automatically power off if a key is not pressed within 1 to 10 minutes (user configurable).

nice unit.

Update: The one they shipped was a MD100E unit and not the FL40 unit pictured. These are essentially the same unit but no SD card. That turned out to be an issue with inventory and the vendor should be updating the web site. Unit still has tons of internal memory so no issues.
One remaining though is where to download updated software or firmware for this unit. The reason for updated firmware is some of the interface has minor bugs (overlapping text) that has likely been fixed since the unit was produced in 2019. Yes.. date is 2019-11-22. and while not bad from a hardware side, it's still wise to be able to verify updated firmware.
Now for accuracy, it was in contention with the more pricey one at my cardiologist's office and good enough for routine checks at home. (all I was expecting). I do wish they would update the software though as it only runs if the screen resolution is exactly 1024x768. I have a higher resolution and it won't get past that popup. Looking online I could not find updated software either.


its a great ecg but software needs a lot of work

Works great so far! Software could use some improvements though.

Unit 5 Star, Software ?????

Great but much trial and error to use. Software tough. Saved scans couldn't bring back easily. Found files in C:\Users\(my computer)\AppData\Local\VirtualStore\ProgramFile(x86)\Keep-It-Easy Unique to Windows 10 I guess. Helps to be computer savvy. Hand Unit works great. First one was defective, but warranty honored. Recommend Printing to Microsoft PDF, not Adobe.
