DISPOSABLE LEVELER

摘要

A disposable level gauge is provided to improve analysis reliability for sample by measuring each water pipe using new level gauge, so that cross contamination is prevented. A disposable level gauge comprises a synthetic resin film such as a medium block film(20) and a scale paper(10) disposed at two sides of the synthetic resin film. The synthetic resin firm is made of polyethylene and has a length longer than a depth of underground water. The water level is measured through absorbing power of the scale paper. The disposable level gauge is rolled to be kept. A scale(31) of 0.01m and a scale(30) of 0.05m are formed on the scale paper.
