Avaliação de diferentes hipsômetros na estimativa da altura total.

This study aimed to assess the accuracy of different hypsometers: Blume Leiss [BL], Suunto [ST], Relascope [RL], Vertex [VX], Haga [HG] and TruPulse [TP] for height measuring. Data were collected from telescopic poles (A, B and C with 4.45, 10.75 and 7.8 m, respectively) using thirteen different observers. The height was analyzed by analysis of variance in randomized block and tested by Tukey test. The t test (99% significance) was also used to compare equality between real total height of each telescopic pole and heights measured with hypsometers. The results showed that only the RL was different from other hypsometers when all were analyzed together. The hypsometers VX, HG and BL showed the best results in all analyzes, presenting a high semblance to the real height. [ABSTRACT FROM AUTHOR]
