The Welch Allyn DS66 trigger aneroid is an innovative gauge with a trigger-style air release valve. The ergonomic design features soft plastic inserts at key touch points that make it comfortable to use. Featuring gear-free technology, this gauge will remain in calibration longer than traditional aneroids, continuing to provide accurate readings over time. This set comes with a reusable, two-piece adult cuff with a single tube.
delivery took over a week. do not understand why the high cost of the mailing and delivery why it took so long to deliver via fedex the product. Otherwise, the product is excellent, replacing my previous model over 15years old. definitely comfortable to handle and read with a generous size cuff.
