The FD320 Fetal Doppler features a high-resolution LCD for displaying a real-time FHR waveform and fetal heart rate reading. The doppler uses premium components such as an ultrasonic signal transmitter and receiver, an analog signal processing unit, FHR calculating unit, and an LCD control unit, etc. The unit's color-coded alarm feature automatically alerts to FHR measurements detected outside the normal range. Interference-free audio output through the headphone jack allows for clear audio recording and supports external headphones or speakers.

The FD320 has three working modes: real-time FHR display mode, averaged FHR display mode, and manual mode. This baby doppler also includes continuous monitoring for up to 8 hours of working time usage. The water-resistant probes are interchangeable and can be chosen based on the requirements of each user. For most full-term pregnancies, the 3.0MHz probe suits most early-term and general-purpose pregnancies. The 2.0MHz late-term pregnancy probe accommodates depths of 10cm or more.


Three Working Modes:
  • Mode 1: A heart icon is displayed when the heartbeat is detected and the real-time heart rate is displayed numerically
  • Mode 2: A heart icon is displayed when the heartbeat is detected and it averages the heart rate for a more stable reading
  • Mode 3: This mode allows the user to calculate an average heart rate over a specific period of time by manually pushing a button to start & stop the time

Features:

  • FDA & CE Approved
  • Listen through the powerful built-in speaker or with headphones
  • Easy to read LCD screen with on/off back light mode
  • Digital fetal heart rate displayed
  • Auto-off feature & low battery consumption to ensure many hours of usage
  • Battery icon indicating remaining battery life (AA batteries)
  • Weighs less than 1/2 a pound
  • Compact design with buttons designed to withstand repeated usage without wearing or breaking
  • * Recording/Audio Cable is optional


  • Includes everything the FD300 has above, but FD320 in addition has:

  • Colored LCD high resolution display
  • Heartbeat wavelength display and bar graph
  • Color coded alarm changes to red when the fetal heart rate range is out of the normal range



Choosing Probes:

  • 3 Mhz: The 3 MHz is an early term and general purpose Doppler probe. It will work very well through most full-term pregnancies. A 3 Mhz is more sensitive than a 2 Mhz probe and can pick up a baby's heartbeat as early as 8-10 weeks gestation.
  • 2 Mhz: Designed to accommodate late term pregnancies since it works best at 10 cm and larger depths.
  • 8 Mhz: The 8 MHz probe is designed for Vascular monitoring and provides vein blood flow and artery detection. This probe provides the highest resolution and detects a broader range of frequencies than the other probes. The probe's intended use is for examining surface vessels.

Nice
I love it. It's a nice slim wallet. Nothing special, but looks really nice, works well. I've been using it for a month with no problems. It's nicely lined, seemingly well made, etc. I got a good price on it, so I'm happy.

Wonderfully made, but not well sized for US currency
This is a very nice slim billfold, but unfortunately, it's not well sized for US currency. Probably for Euros. US Dollars fit, but it's a touch too narrow across to easily insert a bill. So you'll have to very diligently straighten and align a greenback to make it fit.

Class and elegance
Color: Gold
I absolutely love this watch! My grandson also loved mine so I bought him one for Christmas. This is the 4th Citizen watch I have purchased. 2 are ecodrive and 2 are battery powered. I have to say I do like the battery powered watches better for their weight, lots lighter on your wrist than the ecodrive I regularly used to wear. This watch has taken a beating, as it seems like I'm always hitting the face on something, and has performed beautifully. I figured that I would've replaced the crystal by now but I haven't had to. My grandson admired and wanted mine, (I can't part with it because it has special meaning) so I bought him the identical model. I have worn mine in water, extreme cold, and out to dinner. It looks and performs beautifully. This watch is classy, elegant and beautiful and it's not a giant timepiece although you may have to take it to your local jeweler for band sizing. There's videos on u tube but I don't recommend trying that for taking links out. I say beautiful because as a woman wearing this watch it's not overwhelming and screaming look at me I'm wearing a man's watch. However this watch is handsome looking on men, my husband and grandson lol. The band is smooth, doesn't kink or pinch my wrist and when fitted properly it doesn't end up face down or sliding over and staying over on the outside of my wrist. Only drawback for me is I'm not used to the day dial and sometimes when setting the time bc some months are shorter I tend to be a day ahead, easy fix. I've gotten lots of compliments on this watch and would definitely buy it again
