An optical pyrometer is an instrument used to measure high temperatures, often in industrial applications, by comparing the intensity of radiation emitted by a hot object to that of a calibrated light source. Unlike contact thermometers, it measures temperature without making physical contact with the object, making it suitable for measuring extreme heat such as
A function generator is an electronic device used to generate electrical waveforms over a wide range of frequencies. It is widely used in the fields of electronics, communications, and testing to create specific signals for testing, calibration, and experimentation. Figure 1: Block diagram of a function generator.
A pH meter is an electronic instrument used to measure the acidity or alkalinity of a solution, expressed as pH. The pH scale ranges from 0 to 14, where a pH of 7 indicates neutrality, values below 7 indicate acidity, and values above 7 indicate alkalinity. A pH meter provides precise pH readings, which are
An Energy Meter, also known as a watt-hour meter, is an electrical device used to measure the amount of electrical energy consumed by a residence, business, or electrically-powered device. The energy is typically measured in kilowatt-hours (kWh), which is the standard billing unit for energy consumption.
A Pitot tube is a commonly used variable head, fluid velocity measuring device. It is also called as Pitot static tube or air speed indicator (in aircraft). Figure 1: Pitot Tube.

A turbine flow meter is a device used to measure the flow rate of a fluid (liquid or gas) by converting the kinetic energy of the fluid into rotational motion of a turbine. The flow rate is proportional to the rotational speed of the turbine. Figure 1: Turbine Flow Meter.
The McLeod gauge is used for measuring pressures ranging from 0.01 micron to 1 mm of Hg. Figure 1: McLeod Gauge.
