In this instance, the relationship between the critical meniscus heights (CMH) of several liquids to the extraction speed of a rod submerged in them, have been analyzed. A limitation of a previous interrogator used for the purpose had been light absorption by the liquid due to the used bandwidth of the readily-available light source, i.e., C-band. The newly proposed technique addresses this limitation by utilizing a broadband light source instead, with a Si-photodetector and an Arduino. In addition, the Arduino is capable of extracting data at a relatively faster rate with respect to the conventional optical interrogator. The use of a different operational wavelength (850 nm instead of 1550 nm) increased the r2 and the sensitivity of the sensor. The new setup can measure surface chemistry properties, with the advantage of being comparatively cheaper than the conventionally available interrogator units, thereby providing a suitable alternative to conventional measurement techniques of liquid surface properties, while reducing material waste, i.e., in terms of the required volume for detection of a target parameter, through the use of optical fiber.<\/jats:p>","DOI":"10.3390\/s21238130","type":"journal-article","created":{"date-parts":[[2021,12,6]],"date-time":"2021-12-06T03:10:38Z","timestamp":1638760238000},"page":"8130","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Viscosity Dependence of the Critical Meniscus Height with Optical Fiber Sensors"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2492-8722","authenticated-orcid":false,"given":"Leonardo","family":"Binetti","sequence":"first","affiliation":[{"name":"School of Engineering and the Built Environment, Edinburgh Napier University, Edinburgh EH10 5DT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fraser","family":"Simpson","sequence":"additional","affiliation":[{"name":"School of Engineering and the Built Environment, Edinburgh Napier University, Edinburgh EH10 5DT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8488-2992","authenticated-orcid":false,"given":"Lourdes S.
