  2. Electrostatic fieldmeter - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_Fieldmeter

    An electrostatic fieldmeter, also called a static meter is a tool used in the static control industry. It is used for non-contact measurement of electrostatic charge on an object. It measures the force between the induced charges in a sensor and the charge present on the surface of an object. This force is converted to volts, measuring both the ...

  3. Electrical conductivity meter - Wikipedia

    en.wikipedia.org/wiki/Electrical_conductivity_meter

    An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. [1] It has multiple applications in research and engineering, with common usage in hydroponics, aquaculture, aquaponics, and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.

  4. EMF measurement - Wikipedia

    en.wikipedia.org/wiki/EMF_measurement

    An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.

    en.wikipedia.org/wiki/Automatic_meter_reading

    The meter communicates to its collection point using 900 MHz mesh network topology. Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and ...

  6. Electrostatic voltmeter - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_voltmeter

    Principle of operation. An electrostatic voltmeter uses the attraction force between two charged surfaces to create a deflection of a pointer directly calibrated in volts. Since the attraction force is the same regardless of the polarity of the charged surfaces (as long as the charge is opposite), the electrostatic voltmeter can measure DC ...

  7. Field strength meter - Wikipedia

    en.wikipedia.org/wiki/Field_strength_meter

    Field strength meter. Field strength meter is actually a simple receiver. The RF signal is detected and fed to a microammeter, which is scaled in dBμ. The frequency range of the tuner is usually within the terrestrial broadcasting bands. Some FS meters can also receive satellite (TVRO and RRO) frequencies.
