Scleral Contact Lenses for Other Eye Problems. In addition to keratoconus, scleral contact lenses can be used for eyes that have undergone a cornea transplant, and for people with severe dry eyes caused by conditions such as Sjogren's syndrome, graft-versus-host disease (GVHD) and Stevens-Johnson syndrome.
Aneroid sphygmomanometer with an adult cuff. A sphygmomanometer (pronounced /ËsfÉªÉ¡moÊmÉËnÉmÉ¨tÉr/. SFIG-moh-mÉ-NOM-i-tÉr) or blood pressure meter is a device used to. measure blood pressure, comprising an inflatable cuff to restrict blood. flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what. pressure blood flow is just starting, and at what pressure it is. unimpeded.
While ammeters are used to measure the currents, the voltmeter is used to measure the voltage. Both the devices are different in terms of functionality and circuit placement. An ammeter is an instrument that is used to measure the currents in a circuit.The currents are measured in amperes (A). Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.ultimeters can also be utilized in place of both ammeters and voltmeters. A multimeter is an instrument that can be used to measure both, currents as well as voltages. It can also perform as ohmmeters, a device used to measure resistance. Multimeters are available in analog or digital format. Ammeter.
