The Lightning X LXBPC Aneroid Sphygmomanometer is built like the original and best! The only difference is that we now use a calibrated numeric dial instead of a column of mercury. This style is still the most dependable and widely used blood pressure monitor in the emergency services industry, but is easy enough for anyone to learn to use at home. Our "blood pressure cuff" (as we like to call it) is built tough to meet or exceed the highest industry standards, without breaking the bank. The bladder, tubing and bulb are made of PVC and are 100% latex-free. Also included with the BP Cuff is a zippered vinyl carrying pouch designed to protect the gauge from damage and make the entire kit easy to transport. The LXBPC is a great addition to any starter EMT bag, nurse kit or health concious individual, and is not only affordable but built with quality to last for years to come!
