Product Description
Vibration Meter
Broadband applications and features suitable for large values of measurements, such as large low-frequency displacement measurement. With the maximum peak, maximum RMS to keep functions such as multi-point burst in the maximum peak and maximum intensity values. To external filters.
1, with the state statutes limited Measuring Instruments charge amplifier all the features and indicators.
2, sub-points: an effective solution of the integral circuit frequency response of narrow, easily susceptible to interference and saturation drift cover disease.
Integral characteristics of the circuit is: Compared with the linear, high-frequency attenuation of low frequency amplification.
3, not only can measure vibration and shock signals positive peak, negative peak, RMS and be permanently maintained, and can measure the range of sizes ranging from vibration and shock signals to maintain the maximum and be permanent.
4, True RMS Measurement: True RMS measurement date used by the U.S. Circuit accurate, stable and reliable.
5, intensity measurement: measurement results meet the ISO2954
6, external filter
7, AC220V and DC12V two kinds of power supply, integrated circuit technology, portable structure (smaller than similar products in 1 / 2), dust shock, both in the laboratory, especially for the field and on-site.
8, three semi-LED display digital panel meters, accurate and clear.
