Kolida KTS-442L Total Station

KTS-442L infrared laser total station with advanced absolute encoding angle measurement technology, greatly improving the accuracy and stability of the angle measurement. Boot without initialization, in the measurement if the power off, after the restart still retain the original information, greatly facilitate the measurement workers. At the same time, KTS-442L with a circuit board, absolutely international level, completely solve the integration problems with crosstalk, production, maintenance efficiency improved several times. In addition, tight rubber ring waterproof, so that the waterproof and dust level to reach IP56 level.
