The ZET 019-U2 multifunctional spectrum analyzer is designed to measure the spectral components of signals with various accelerometers and microphones plus the correlation structure of signals, generate electrical signals with normalized metrological parameters, and measure noise and vibration levels in 1/3-octave bands, which allows you to use it as a vibrometer and sound level meter. It can be connected to a PC and powered by a USB 2.0 bus. Its built-in ICP amplifier for sensors with integrated electronics allows you to connect accelerometers and ICP microphones without using intermediate amplifiers and smart TEDS accelerometers (sensors that support the IEEE 1451.4 connectivity standard).

Scope of use
	Leakage detection and control systems
	High-frequency precision measurements
	Monitoring and diagnosis using acoustic emission
	Continuous monitoring of prolonged high-frequency processes
	Hydroacoustic measurements

The ZET 019-U2 will be indispensable when you need to perform various kinds of tests that do not permit the use of stationary measuring devices, though its technical and metrological characteristics are just as good. The internal disk of up to 32 Gb allows you to collect data offline for subsequent processing on a PC. Its low weight and small size make it suitable for hard-to-reach places when diagnosing rotating parts, gears, bearings and turbines. It can process signals in real time and process recorded temporary implementations.

The analyzer can be equipped with additional accessories for connecting various sensors: force sensors, acceleration sensors, microphones and accelerometers with 4–20 mA standard current output. The analyzer can also be equipped with an adapter to provide Wi-Fi access in real-time.
