星枫 instruments, laser range finder [Model], Changsha laser rangefinder provided by 星枫 instruments. We are Nanchang Xing Feng Instrument Co., Ltd. (www.xingfengyiqi.com) located: Nanchang, Jiangxi professional: rangefinder, coating thickness gauge, ultrasonic thickness gauge, hardness tester, vibrometer Germany Hilti handheld laser rangefinder type PD42 PD42 PD40 addition to all the features also has the following features: more features - volume measurements can be performed laser rangefinder model, accumulating multiple measurement area, more convenient and practical - have a maximum / minimum measurements, facilitate the identification and verification of parallel lines straight angle - triangulation function (Pythagorean theorem), and there are three kinds of measurement modes, easy to measure inaccessible distances - delay measurements (up to 20 seconds), the data storage function (last 30 group ? the data) is more convenient to use - Built-binoculars, suitable for long distance and outdoor measurements - Built-level vertical beads, improve vertical measurement accuracy - there are four to choose from starting measurement (front, rear, extension piece laser rangefinder manufacturers, tripod threaded connection the center) - with a standard tripod screw (1/4 ') interface, easy to accurately measure the built telescope maximum and minimum estimates, put the line features standard tripod interface, easy to accurately measure three indirect measurement of the actual measurement Application 419D laser rangefinder, Brand: Fluke 1: Measure the distance up to 80m, higher accuracy: + / -1 mm; 2: When measuring distances, Tripod mode allows you to rangefinder mounted on a tripod; 3: Fast calculate the area (square feet / meters) and volume; 4: simple addition and subtraction functions; 5: Using the other two measurements, the Pythagorean theorem can indirectly measure the height; 6: 20 pen before the store measurement data, for quick reference distance; 7: Battery life measurements available for 5000, and has automatically shut down the laser and auto power off function; 8: Measure the distance of the two most advanced laser technology; 9: Just one button operation to completion of the instant measurement; 10: stronger environmental protection: IP54 protection class, with dust and splash resistant features
