An important aspect in recording the level of the meniscus is the position of the observer. It is not possible to register the level correctly if the meniscus is viewed from above or below; To measure a meniscus, the observer’s eyes should be at the same height as the level of the meniscus in the container .
It is important that the procedure is performed in the same way each time a measurement is made. doing so does not introduce errors in the measurements associated with differences in the application of the procedure, such as the position in the observation of the meniscus.
As a curious fact, to say that the word ” meniscus ” comes from the Greek term used for ” half moon “; It makes sense if we consider that the shape of the meniscus is similar to a crescent.
