They often have a longer range, exceeding 200 feet, and may include features like target plate recognition to lock onto distant objects more reliably.
Indoor laser measures are generally sufficient for most home improvement and DIY projects. They prioritize accuracy at shorter ranges and may not have the same level of sunlight compensation. Some indoor models lack a viewfinder, relying solely on the laser dot for targeting. While some indoor models can be used outdoors, their performance will be significantly reduced in direct sunlight, leading to inaccurate readings. Choosing the right type depends on the primary application and environmental conditions.
How do I measure an indirect distance (like the height of a building) with a laser measure?
Laser measures utilize the Pythagorean theorem to calculate indirect distances. This involves taking multiple measurements – the distance to the base of the object, the angle to the top of the object, and the distance from the ground to the laser measure’s height. The device then automatically calculates the height using the formula: height = distance to base * tan(angle) + laser measure height.
Most laser measures with Pythagorean theorem functionality have a dedicated mode for this purpose. You simply select the mode, take the required measurements as prompted by the device, and it will display the calculated height. Accuracy depends on the precision of the angle measurement and the levelness of the ground. Some advanced models offer automatic angle detection, simplifying the process. It’s crucial to understand the principles of the Pythagorean theorem and ensure accurate input measurements for reliable results.
What is an IP rating, and why is it important for a laser measure?
An IP (Ingress Protection) rating is a standardized system (IEC 60529) used to define the level of protection a device offers against solid objects and liquids. It consists of two digits: the first indicates protection against solids (dust, tools, etc.), ranging from 0 (no protection) to 6 (dust-tight), and the second indicates protection against liquids (water, rain, etc.), ranging from 0 (no protection) to 9K (powerful water jets).
For a laser measure, a higher IP rating is crucial for durability, especially in demanding environments like construction sites. An IP54 rating, for example, indicates protection against dust ingress and splashing water from any direction. An IP65 rating offers dust-tight protection and protection against water jets. Choosing a laser measure with an appropriate IP rating ensures it can withstand the rigors of your work environment, preventing damage and maintaining accuracy over time. A lack of IP rating suggests limited protection and a shorter lifespan in harsh conditions.
