an 'ammeter'
A conductivity meter, sometimes called a conductivity probe or sensor, is the instrument used to measure the conductivity of a solution. It typically measures the ability of a solution to conduct electric current, which is influenced by the concentration of ions present in the solution.
A mass spectrometer is an instrument that measures the atomic mass of atoms and molecules. It does this by ionizing the sample and then separating the ions based on their mass-to-charge ratio. The resulting mass spectrum provides information on the relative abundance of different isotopes present in the sample.
A hygrometer is commonly used to measure dryness in the air. It provides a quantitative measurement of the amount of water vapor present in the air, indicating the level of dryness or humidity.
An albuminiter is an instrument for measuring the amount of albumen present in a liquid.
A milliammeter is a sensitive instrument placed in series in a circuit and is calibrated to measures current going through it, and therefore the whole circuit, without presenting enough resistance to affect the current going through it or reducing the voltage available to the rest of the circuit. A voltmeter is a milliammeter used in parallel to the circuit. Since the milliammete has very little resistance, if it is used this way it will present as a short to the rest if the circuit, not give a valid reading, and probably burn out. To use a milliammeter as a voltmeter, a significantly large resistance needs to be placed in series with the milliammeter. If the resistance is large enough, but not too large, it will prevent the meter from being a short, not affect the circuit load but still allow enough current to go through the meter to get a reading. If you want to measure AC (alternating current) you will also have to include a rectifier circuit. To be useful as a voltmeter, the meter will need to be calibrated, a tedious job since the meter responses probably are not linear. Modern multimeters are available that will act as a voltmeter with several range setting. You can get them at any electronic or tool store such as Sears, Harbor Freight, or Radio Shack. Even the cheap 10 dollar ones will do a good job for most purposes although professional models that do so much more and with greater precision can be really expensive.

A hygrometer is a weather instrument that measures moisture in the atmosphere. It quantifies the amount of water vapor present in the air to provide information about humidity levels.
A thermometer is an instrument that measures changes in thermal energy. It detects temperature variations in a specific material or environment and provides a numerical reading indicating the level of thermal energy present.
The flow in a circuit is called the electric current and it is measured by voltages. The number of volts that are present in the charge will determine the strength of the electric current.
A hygrometer is an instrument that measures relative humidity in the air. It typically works by measuring the amount of water vapor present in the air compared to the maximum amount that the air could hold at a given temperature.
A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit.

An instrument in which the present value of the quantity being measured is indicated is called an indicating instrument.
The synonym for current is "present" or "existing."
