Bosch GLM15 Compact Laser Tape Measure Review
The Bosch company was founded in 1883 and since then it has been producing various products such as medical instruments, power tools, and industrial equipment. The company’s main product line consists of precision measurement devices which are used for manufacturing purposes. The company’s most popular products include its GML Series of laser measures (also known as “G” series), which consist of two types: the G1 and the G2. These measures are designed primarily for use in engineering applications, but they have proven to be very useful in many other fields including medicine, surveying, construction, and even accounting.
The G1 and G2 laser tapes measure are based on a type of optical fiber called a “bipolar light emitting diode”. Bodies of these fibers are coated with special material that emits a beam of light when an electric current passes through it. When the current is turned off, the fiber absorbs all or part of the light emitted from it. By counting how long each portion of light is absorbed, one can determine the number of cycles per second (CPS) that passed through the fiber. A typical cycle is 1/60th of a second.
Thus, if a pulse travels at 60 CPS, then it will take 1/60th of a second to pass through the fiber and back out again. In this way, the laser can be used like a stopwatch to determine the exact length of an object.
The G2 series is known for its reliability. It is powered by three common “AAA” sized alkaline or lithium batteries and it can run up to two hours (or more) before it needs to be replaced. It is very easy to use. The only controls on the device are a power switch and an “off-tick” button. The “off-tick” button is used to turn the laser on and off.
When the laser is on, it emits a red dot that moves around on whatever surface the device is aimed at (such as a wall). By keeping this red dot in constant motion around the object you wish to measure, the laser can measure its length, width, height, or circumference (or any combination of these) within only a few seconds.
Measuring a flat surface is quite simple. Just move the laser all the way to one end of the flat surface and press down on the “off-tick” button for at least two seconds. The laser will emit a red dot on the opposite end of the surface and the measurement will automatically be saved on the device’s internal computer.
