Abstract:
Different eye tonometers are available for the measurement of intraocular pressure. These devices must be checked in Germany by control measurements every 2 years. For this test, special apparatuses were developed by the "Physikalisch-Technische Bundesanstalt" which are checked by comparative measurements during seminars of this institute or during educational events of the "Deutsche Akademie für Metrologie". 50 test apparatuses were compared during a seminar of the "Physikalisch-Technische Bundesanstalt". The measurements of these investigations show the suitability of these devices for the performance of measuring checks of eye tonometers.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
