Various types of body fat analyzers also called impedance meters are available to the general public. Dexa or dxa stands for dual emission x ray absorptiometry. Skinfold based body fat estimation is sensitive to the type of caliper used and technique. To get the best results measure to the nearest 14 inch 05 cm.
