Skadden SATA Mini Laser Rangefinder Measure VS Steel Tape, The Result Is Unexpected _ Measurement Original Title: Skadden SATA Mini Laser Rangefinder Measure VS Steel Tape, the Result Is Unexpected In addition to screwdrivers, the necessary tools that people who love hands-on home decoration must often use may be tape measures. Ordinary people may have a steel tape measure for measuring length, height and so on. However, the steel tape measure also has drawbacks. It is spring steel inside. There are safety risks in the process of shrinking spring steel, which is easy to scratch hands. Today, I bring a more portable, safer and more accurate household measurement tool, the SATA Mini Laser Rangefinder. Very compact packaging, the effective measuring distance of this product is 40 M, using laser measurement, built-in 180 mAh rechargeable lithium battery. With a portable lanyard,custom tape measure, the product is very compact, and the lanyard can be left behind when it is used. Expand the full text The front of the product is a liquid crystal display screen, the lower part is a multi-function key, and the back side is the product model and other information. Press it for about 1 to 2 seconds to start the machine,bespoken tape measure, and press it for about 4 to 5 seconds to shut down the machine. When measuring, you only need to press the multi-function key lightly, and the data value can be displayed accurately in an instant. The top of the product is composed of aspheric infrared laser transmitter and PMMA transparent laser receiver, one transmitter and one receiver form a closed-loop, so that the machine can instantly calculate the actual distance value, the actual measurement accuracy can be controlled within ± 2 mm, in fact, the measurement error of ordinary steel tape is limited by whether it is 100% straightened and naked eye recognition. So the error is actually very large, laser rangefinder laser measurement distance, mini tape measure ,bra tape measure, without manual intervention, can achieve very small error. The bottom of the product is a micro-usb charging port. There is no standard charging cable and charging head. It can be charged by an ordinary 5V/1A charger. It can be fully charged quickly in 2 hours. When it is fully charged, it can be measured about 4000 times. However, there is no warning light for shutdown charging. Only when the battery icon is turned on, it will flash to indicate that it is being charged. When measuring, it may be in the dark, so the screen has joined the high-definition backlight, whether in the light or in the dark, it can display clearly. Press it lightly, and the "" icon in the upper left corner will flash to enter the measurement. Press it again, and the result will be displayed in about 1 second. The measurement result is accurate to 3 decimal places, reaching the millimeter level. Accuracy test: Skadden SATA Mini Laser Rangefinder Steel tape I am more concerned about the accuracy of using this kind of product, and I have also done the actual comparative test for the accuracy, which is used to prove to the friends who have doubts about this kind of product. The most common standard size in my home is floor tile, and the size of floor tile in my home is 800800 mm. At the same time, I use steel tape and SATA mini laser rangefinder to measure. By comparing the measurement results, the measurement result of SATA mini laser rangefinder is 0.799 mm, and the visual measurement result of steel tape is 0.801 ~ 0.802 mm. The accuracy of laser rangefinder is higher than that of steel tape. Specify location to roof height Indoor length measurement For example, if you want to decorate, calculate the area of the house, or when you need to add new furniture at home, you can use this rangefinder to measure the length, width and height. There is basically no big error. The maximum effective measurement distance of SATA mini laser rangefinder is 40 M, which basically covers the whole house. Even if it is a large villa of four or five hundred square meters, The length and width are generally enough, the product is resistant to falling, the product will not be broken when it is dropped, and it can also be put in the pocket when it is used. Write at the end: As a household measuring tool,seamstress measuring tape, the laser rangefinder is much better than the steel tape, and it is safe and convenient, and its accuracy is not worse than the tape. Perhaps the only thing I am not satisfied with this rangefinder is that there is no prompt when it is turned off and charged. Everything else is quite satisfactory.
