The unit can take measurement of distance, calculation of area and volume equipped with a laser pointer to target.

This ultrasonic distance measure is a multi-functional measuring tool which provides non-contact measuring of lengths over greater distances. It can take measurement of distance, calculation of area and volume. It equipped with a laser pointer to identify the target for additional verification of testing point.Multiple measurements may be automatically added to allow for overall measurement greater than 20 meters. It provides automatic conversion between imperial and metric unit of measurement.
