If the diameters are measured from both ends (top-root), it is possible to use two calipers connected wireless via Bluetooth. In this way the other caliper works as a slave and sends the measured diameter to the master caliper which stores both measurements. Barcodes can be read utilizing Bluetooth and Mobile Caliper application.
Calculation of the volume can be done directly in the caliper and printed on a portable printer or measurements can be transferred to PC for further computing.
Masser Oy can supply national specific calculation programs running in the caliper.
