Panasonic EW3109W

Rating: ★★★★½

The Panasonic EW3109W Portable Upper Arm Blood Pressure Monitor is a simple and affordable blood pressure monitor where accuracy is no issue.  The features of this specific model should be the deciding factor as to whether this would be a good fit for you.  It stores a maximum of 90 readings, does not have a two user mode, and uses a Digital Filter Technology that eliminates noise factors that can contribute to an inaccurate reading.  It’ll also pick up signs of hypertension.   In short, you get a decent bang for your buck here if you’re someone that wants a basic accurate blood pressure monitor with a couple extra useful features.  More details below.

Where To Buy?

I always recommend buying from (check current discounted price).  They have this model for over 40% off, and it qualifies for free shipping.  I also find it difficult to find blood pressure monitors like these in stores.  Amazon has a lot of depth in this with these devices and can surely show you other options if this one doesn’t fit well.

How Many Readings Does It Hold?

It holds up 90 individual readings.  It doesn’t have a two user mode in order to keep the readings separated in case you have a spouse or someone you want to share it with.  So, it’s probably better for a single user, unless you like to record your data separately on an excel sheet, paper, or other means.

Cuff Size And Inflation

It comes with an extra large cuff that can fit arms up to 17inches, which is pretty big.  Like other automatic blood pressure monitors, it auto inflates to a proper inflation level in order to get an accurate reading.

Is It Accurate And Consistent?

The Panasonic EW3109W Portable Upper Arm Blood Pressure uses a technology called Digital Filter Technology.  DFT helps to eliminate noise factors that can give you an inaccurate reading.  It does this by isolating and detecting the pulse oscillation, which is the true key factor in getting a blood pressure reading.
