Thermometers come in different types, including liquid-in-glass thermometers (like mercury thermometers), digital thermometers, infrared thermometers, and thermocouples, each suited for specific temperature measurement applications.

• Thermocouple: A thermocouple is a temperature sensor made of two different metal wires joined at one end. It produces a voltage proportional to the temperature difference between its ends, making it suitable for measuring high temperatures in industrial processes, scientific research, and engineering applications.

Measuring Angle:

• Protractor: A protractor is a geometric tool used to measure angles. It typically has a semicircular shape with degree markings, allowing users to measure and draw angles accurately in mathematics, engineering, and architecture.

• Clinometer: Clinometers are devices used to measure angles of elevation or inclination. They are commonly used in surveying, forestry, geology, and outdoor activities like hiking and mountaineering to measure slope angles and vertical inclinations.

Measuring Pressure:

• Pressure Gauge: A pressure gauge is an instrument used to measure pressure in a fluid (liquid or gas) or a pneumatic system. It provides readings in units such as psi (pounds per square inch), bar, or Pascal, depending on the application.

• Manometer: A manometer is a type of pressure-measuring instrument that uses liquid columns to measure the pressure difference between two points. It’s commonly used in HVAC systems, plumbing, and fluid mechanics for measuring pressure levels accurately.

Measuring Electrical Quantities:

• Multimeter: A multimeter, also known as a volt-ohm meter (VOM), is an electronic instrument used to measure voltage, current, and resistance in electrical circuits. It’s a versatile tool for electricians, technicians, and engineers working with electrical systems and troubleshooting issues.

• Ammeter: An ammeter is a device used specifically to measure electric current in amperes (amps). It’s connected in series within an electrical circuit to measure the flow of electric current accurately.

• Voltmeter: A voltmeter is used to measure electrical voltage in volts (V). It’s connected in parallel to the circuit or component being measured to determine voltage levels accurately.

• Ohmmeter: An ohmmeter is designed to measure electrical resistance in ohms (Ω). It’s used to test the continuity, integrity, and resistance of electrical components, wires, and circuits.

Measuring Sound:

• Sound Level Meter: A sound level meter (SLM) measures the intensity of sound waves in decibels (dB). It’s used in environmental monitoring, industrial noise control, occupational safety assessments, and acoustic research to measure and analyze sound levels and frequencies.

Measuring Light:

Measuring Radiation:

• Geiger Counter: A Geiger counter is a radiation detection device that measures ionizing radiation levels. It’s commonly used in nuclear facilities, environmental monitoring, radiation safety, and radiological emergency response to detect and measure radioactive contamination.

• Dosimeter: A dosimeter is a personal radiation monitoring device worn by individuals working in radiation-exposed environments. It measures and records the cumulative dose of ionizing radiation absorbed by the wearer over time, ensuring radiation safety compliance and monitoring radiation exposure levels.
