Sound level meters and noise dosimeters are used in sound and noise analysis. Applications include industrial safety, traffic noise studies, and scientific noise measurement

Measurement microphones are most commonly condenser microphones, which convert sound pressure to an output that is then converted into a reading such as sound pressure level (SPL

KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA). Apparent power is the combination of a circuit’s true power and reactive power.

Dry material (powders) level sensing devices are used to measure levels of solid, dry materials in either continuous or point values represented with various output options.

Analog multimeters are instruments that are used to measure electrical quantities such as voltage, current, resistance, frequency and signal power

Analog dBm meters are instruments that measure signal power. They display values on a dial, usually with a needle or moving pointer.

Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends

Eddy current instruments are nondestructive testing (NDT) devices that induce detectable eddy currents in conductive materials. They are used to detect flaws, determine thickness, inspect welds, measure conductivity, and sort alloys.

Digital voltmeters are instruments that measure voltage or voltage drop in a circuit. They use solid-state components and display values digitally.

Clamp meters are ammeters that can measure current without the need to disconnect the wires where the measurement occurs. They provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends

Acoustic and vibration test equipment repair services includes repair and other services for vibration, acceleration and acoustic test equipment, instruments and sensors.

Audio microphones are designed for sound reception and recording applications (speech and music).

Active noise and vibration control systems are products such as controllers, sensors and actuators that monitor and cancel noise and/or vibration.

Anechoic chambers are specialized chambers designed for electromagnetic or sound waves.

Noise figure meters measure the noise contribution of an amplifier relative to a noise-free amplifier at a reference temperature. For most Ku-band amplifiers, values are expressed in decibels (dB
