This is non-contact distance meters per laser beam reflected to the point to be measured. The range of devices includes from the ones that operate only in low light conditions to the ones that operates outdoors without being affected to solar radiation. The model also determines the maximum distance measurement and the accuracy and resolution of it.
This is non-contact distance meters with an ultrasonic beam reflected to the measurement surface. The devices are suitable to work outdoors without being affected by solar radiation, but need a significantly large area of reflection being only suitable for measurements on large surfaces, walls, ceilings, etc.. Also performs the calculation of volume from the measurement of the three variables.
