The M.P. Measuring Tape (MPMT) is the tool for measuring of the inside and the outside dimension. The MPMT is particularly useful instrument for measuring of the distances located between the surfaces. This tool is provided with the special arrangement, which allows to read the internal distance without using of any additional facilities or calculations. In addition the MPMT is facilitated with the arrangement for adjustment of the spring tension. This feature allows to recondition the spring, when the last one is getting weak.
