The sources to purchase a measuring device is as wide and varied as the number of devices needed to do the specific jobs intended. The simplest and most common of all measuring devices would be the straight rules. This measurement tool can be purchased in a number of retail stores ranging from a variety store to a big box store. The major decision for this measurement device would be whether you want a plastic one, a wooden one, or a metal one. One must also decide on the scale that is required of the measuring device as well as the graduations. Of course the price will vary depending on one's choice, but rest assured that whichever one is picked will be relatively inexpensive.
The next level of measurement devices would be the tape measure. This distance meter is available in various lengths and width and made with many types of materials. The buyer of this distance meter must first think about whether they would prefer an open or closed reel type. The open type would be best suited for outdoor use or dirty environments. This measuring device is marked so that it could measure inches, feet, or meters. The open reel measurement device is available in lengths that are longer than the closed type. For example, an open reel type will go up to 300 feet at a price of around $200 while a closed distance meter will go up to 50 feet at a price of $15.
The laser distance measuring device is also known as the electronic tape measure. This laser meter is very simple to learn how to use where by pointing the laser beam at an object this measurement device will display the distance right on the LCD display. These distance meters are capable of displaying multiple units of measure, all one must do is cycle through the display until the appropriate reading is found. These laser meters are easy to measure wall to wall distances as this distance meter will measure from the back of the unit to the opposing wall thus giving an accurate reading. The same goes for measuring floor to ceiling by placing the unit on the floor and aiming it towards the ceiling. In purchasing one of these laser meters one must know the distances to be measured. Another factor in deciding which measuring device to purchase is the accuracy required.
