Finger Pulse Oximeter AH-50D Plus with USB and Sofware

confusion : AH-50D plus and CMS 50D plus seems to be the same (at least that's what the vendor responded when I received a CMS-50 D plus instead of AH-50D plus) . AH-50D plus is sold at higher price ....the 'plus' is what gives value to this device as it can record for 24hours and you can upload the data on a computer.Software included:could not read the mini cd included . Found a site to download it , but not from official site ...Software very 'rough' not very user friendly on how to upload data after recording pulse ....You have to keep it recording on the device ,run the program on your pc and set recording off only after connecting to the app (and there are 2 different apps).

PROS- Readout/display crisp (I like the TFT display). Works well (there are only so many ways to skin a cat). It does record. Comparing readings to several other instruments +/- one digit (LSD) different. Very well packed. Software miniCD loaded painlessly, App;ication actually work nicely.CONS- Connector choice on Oximeter (USB micro-B) is WRONG! WRONG! WRONG! WRONG! The connector on the Oximeter does not carry USB signals. All the USB magic is in the cord supplied. If you try to use a real USB cable the host computer (WIN, UNIX, MAC, 5 bit Baudot) will reject it. No way to secure the Oximeter to a finger for overnight recording. Did I mention the connector? other than that...

I was pleasantly surprised by both the price and the operation of this device. I use it both as a real-time heartbeat monitor for my exercise bike and to check oxygen levels while sleeping, using the record function. The firmware on the device was version 4.6. The software that came with it on a mini cd for windows and works fine though using takes some getting used to.If your computer cannot read the small disk you can copy the files from a computer that does --or download it from Facelake,. The last time I looked the online download was an earlier version than that which came on my disk. ,
