Vibration Analysers

Since 2004, ROZH, now RONDS, has focused on research and development of online condition monitoring equipment, possessing more than 50 proprietary intellectual property rights, providing a complete solution in the predictive maintenance field. In collaboration with universities and national research institutes the ROZH RH series, offers leading technology and outstanding performance in hand held predictive maintenance systems. Impact Instruments bring you the RH 711 single channel vibration analyser and the RH 802 dual channel version.

The RH711 Single Channel Vibration Analyzer, available in two versions, is a high performance, user friendly, inspection instrument, used for spot checking, on and off route analysis. In addition to vibration measurement, the unit has an integrated infrared temperature sensor, can be used to perform single plane balancing (when used with the tachometer option), on board processor for datalogging, waverform and spectrum analysis.
