Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.
Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.
Multimeter is an instrument that measures electric equipotential. Equipotential lines can be determined by connecting various points of electric potential or voltage.
A voltmeter measures voltage in volts.
A heightometer.
Any one using a voltage test instrument can measure charge differential voltage.
A voltmeter measures the voltage present in the circut. Voltage is the amount of energy available to push charges through an electric circut.
Multimeter is an instrument that measures electric equipotential. Equipotential lines can be determined by connecting various points of electric potential or voltage.
A thermocouple is an instrument that measures temperature continuously. It consists of two different metals joined together, producing a voltage that changes with temperature. The voltage is then measured by a device to give a temperature reading.
A multimeter can measure different things related to electricity, including current and voltage.
A voltmeter is the instrument that measures electric potential. It is typically connected in parallel to the circuit or component being measured to determine the voltage difference between two points.
In most cases it is a dual-slope integration ADC (analog to digital converter).
All Moving Iron Type measuring instruments major rms value of quantities.
Voltage measures electrical tension, Celsius measures temperature.
An ammeter is an instrument which is used for measurement of current flowing in any circuit

This instrument is a balance.
A multimeter device can measure resistance, current, AC/DC voltage, and it also can determine continuity on an electrical circuit, and its range for current, voltage and resistance is widely variable.
An instrument that measures heat and cold is called a thermometer.
