Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible.
|
|
Oscilloscopes translate an electronic signal into a pattern or waveform on a screen. As it is traced across the screen, the waveform creates a signature of the signal's characteristics.
|
|
Phase meters (phase testers, phase rotation meters) check the phase sequence and phase orientation in three-phase electrical systems.
|
|
Power amplifiers deliver a specific amount of AC power to a load. They are used in audio frequency and radio frequency applications.
|
|
Power meters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.
