instrument.
TachometerScientific Instruments
A Tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually
displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
CardiographScientific Instruments
Cardiograph is an application which measures your heart rate. Cardiograph uses your device's built-in camera or dedicated sensor to calculate your heart's rhythm - the
same approach used by professional medical equipment!
ColorimeterScientific Instruments
A Colorimeter is a device used for measuring colours, or colorimetry. It measures the absorbance of different wavelengths of light in a solution. It can be used to measure
the concentration of a known solute.
DensimeterScientific Instruments
Densimeter is an instrument used to measure density or specific gravity of liquids.
LactometerScientific Instruments
A Lactometer is used to measure the specific gravity of milk to determine the purity of milk.
DiffractometerScientific Instruments
A Diffractometer is a measuring instrument for analyzing the structure of a material from the scattering pattern produced when a beam of radiation or particles
(such as X-rays or neutrons) interacts with it.
OhmmeterScientific Instruments
An Ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. The unit of measurement for resistance is ohms.
MagnetometerScientific Instruments
Magnetometers are measurement instruments used for two general purposes: to measure the magnetization of a magnetic material like a ferromagnet, or to measure
the strength and, in some cases, the direction of the magnetic field at a point in space.
GalvanometerScientific Instruments
A Galvanometer is a type of sensitive ammeter: an instrument for detecting electric current. It is an analog electromechanical actuator that produces a rotary deflection of some type of pointer in response to electric current through its coil in a magnetic field.
VoltmeterScientific Instruments
A Voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an
analog to digital converter.
GramophoneScientific Instruments
A Gramophone is a device for recording and replaying sounds.
SeismometerScientific Instruments
Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of
seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.
Lux MeterScientific Instruments
A Lux meter is used for measuring illuminances in work places.
PhotometerScientific Instruments
A Photometer, generally, is an instrument that measures light intensity or optical properties of solutions or surfaces. Photometers measure: Illuminance, Irradiance, Light Absorption,
Scattering of Light, Reflection of Light, Fluorescence, Phophorescence, Luminescence.
ThermometerScientific Instruments
A Thermometer is a device that measures temperature or temperature gradient. A thermometer has two important elements: the temperature sensor (i.e., the bulb) in which some physical change occurs with temperature, plus some means of converting this physical
change into a numerical value (i.e. the visible scale).
PyrometerScientific Instruments
A Pyrometer is a type of remote sensing thermometer used to measure temperature. Various forms of pyrometers have historically existed. In the modern usage, it is a
non-contacting device that intercepts and measures thermal radiation, a process known as pyrometry and sometimes radiometry.
MicroscopeScientific Instruments
A Microscope is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called
microscopy. Microscopic means invisible to the eye unless aided by a microscope.
SpeedometerScientific Instruments
A Speedometer or a speed meter is a gauge that measures and displays the instantaneous speed of a vehicle.
OdometerScientific Instruments
An Odometer or odograph is an instrument that indicates distance traveled by a vehicle, such as a bicycle or automobile. The device may be electronic, mechanical, or
a combination of the two.
PedometerScientific Instruments
A Pedometer is a device, usually portable and electronic or electromechanical, that counts each step a person takes by detecting the motion of the person's hips.
pH MeterScientific Instruments
A pH meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous
solution. The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or alkalinity.
ProtractorScientific Instruments
A Protractor is a rectangular, square, triangle, circular, octagon, oval or semicircular measuring instrument, typically made of transparent plastic or glass, for
measuring angles. Most protractors measure angles in degrees (°).
