Courtesy: Pattern approval for measuring instruments Personal noise dosimeter A common variant of the sound level meter is a noise dosemeter (dosimeter in American English). However, this is now formally known as a personal sound exposure meter (PSEM) and has its own international standard IEC 61252:1993. A noise dosimeter (American) or noise dosemeter (British) is a specialized sound level meter intended […]
Courtesy: Pattern approval for measuring instruments A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. The diaphragm of the microphone responds to changes in air pressure caused by sound […]
Courtesy: Pattern approval for measuring instruments The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements. The ability to gauge thickness measurement without requiring access to both sides of the test piece, offers this technology a multitude of possible […]

Courtesy: Pattern approval for measuring instruments A measuring instrument is a device to measure a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and […]

The United Nations Environment Programme (UNEP) announced it was becoming climate neutral in 2008 and established a Climate Neutral Network to promote the idea in February 2008. Events such as the G8 Summit and organizations like the […]

Before an agency can certify an organization or individual as carbon neutral, it is important to specify whether indirect emissions are included in the Carbon Footprint calculation. Most […]
