Today we are using so many electronic measuring instruments. Basic knowledge to use these is a must for smooth functioning of our surroundings. WE use thermometers to measure temperatures. Thermocouple is used in most temperature control devices like air conditioners and Heaters. Pressure gauge is important for maintain air pressure in compressors and car tyres. Multimeters are used to check the voltage and current in most electrical instruments. Other instruments mentioned below are also used frequently our surroundings.

We have worked to get you the basic information on all these. These are items of daily use and help us with in a better understanding of our surroundings. Even young children can now have an access to this kind of basic knowledge from the Internet.
