Acoustic Calibrators
-
When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.

Analog Oscilloscope
-
Is a measurement apparatus capable of visually depicting regular changes in electrical activity, such as an electrical current or signal. The resulting data appears as a waveform drawn on a graph with two axes, where the horizontal X axis represents time and the vertical Y axis indicates voltage. In addition, the luminance of the waveform itself is often referred to as the Z axis, which demonstrates the intensity of the activity measured.

Eddy-Current Sensors
-
Eddy-Current sensors are noncontact devices capable of high-resolution measurement of the position and/or change of position of any conductive target. Eddy-Current sensors are also called inductive sensors, but generally "eddy current" refers to precision displacement instruments (or nondestructive testing probes) and "inductive" refers to inexpensive proximity switches. High resolution and tolerance of dirty environments make eddy-current sensors indispensable in today's modern industrial operations.
