Red Point Measure by Huang Qiaokun is a digital measuring instrument that lets you do away with climbing up and down or asking someone to help you to measure your interiors.
How it works? Based on a triangle- related formula: C = (A^2+B^2-2ABcosZ)^(1/2)- the creative working principal, a small device inside the instrument’s rotating axis can easily measure the target length. Using a laser beam measuring technique and simple mathematics, Red Point measures a target length by swinging the two detector arms and using the red light to point at the two ends of the target length, which then appears on the screen. Laser rays carry a certain electromagnetic wave, which when reflected by the object, returns at an interval from the original one. The microcomputer inside the device can calculate the distance.
What’s different? A handy gadget that lets you measure your interiors, without any kind of physical exertion is sure not ordinary stuff. User-friendly attributes and smart design is what sets Red Point apart.
