IKONN AM-1 Digital Angle Measure
Two 20 cm aluminium arms on a locking hinge that read any angle from 0 to 360 degrees to a tenth of a degree, and announce it out loud. For woodwork, home repairs and learning geometry by ear.
Key Features
- Pairs with the IKONN Controller or the free myIKONN app (iOS and Android) to speak every reading aloud in your own language.
- Full 0 to 360 degree range, so reflex angles and internal corners read as easily as a simple corner
- Resolution 0.1 degree, with an option to switch between degrees and radians
- Two 20 cm lightweight aluminium arms, each printed with a millimetre scale to 140 mm and an inch scale in thirty-seconds
- Large knurled locking knob marked TIGHT and LOOSE holds the angle so it can be carried to the work
- Degree scale printed around the hinge, so it also works as a conventional protractor
- Hanging hole at the far end of each arm
- Made by Gemred and sold as IKONN compatible
- Runs on a CR2032 lithium cell
- Size 218 x 20 x 35 mm folded, weight 89 g
Product Information
An angle is one of the hardest things to establish without sight, because a printed protractor is a purely visual instrument: you have to line up an edge and then read a scale you are already touching. The AM-1 replaces the reading step with a spoken number. Open the two arms against the shape you are measuring, lock the hinge, and the IKONN Controller or the myIKONN app announces the angle to a tenth of a degree. The arms are lightweight aluminium, 20 cm each, and they turn through the full 360 degrees, so reflex angles and internal corners are as easy as a simple corner. The hinge carries a large knurled locking knob with a white cap marked TIGHT and LOOSE and curved arrows, big enough to work with cold or arthritic hands. Once you lock it, the tool holds the angle so you can carry it to the saw or the wall and match it there. Both arms are also rules. Each is printed with a millimetre scale to 140 mm and an inch scale in thirty-seconds, and one arm carries a degree scale around the hinge, so it works as a conventional protractor and rule for a sighted partner or teacher working alongside. There is a hanging hole at the far end of each arm. The hardware is made by Gemred and is sold as IKONN compatible. It is a woodworking and home improvement tool, and it is a good way to teach or study geometry and trigonometry when a printed protractor is not readable. It runs on a CR2032 lithium cell.
