Powertech electronics manufactures the 3-in-1 digital rpm/ hour/ frequency meter. Model prhf-03, of this digital rpm/ hour/ frequency meter is designed for users of generator sets. The product specifications conform meticulously to the specific needs and requirements of dg set users and to the characteristics of high quality standards. This newly developed monitoring instrument is based on the latest microcontroller technique, which gives better accuracy, precision, flexibility and reliability as comparable to other digital measuring instruments. Another remarkable feature that furnishes this digital rpm/ hour/ frequency meter, with an edge over others is its multi-functioning capabilities, i.E., it can be used as rpm/frequency/hour meters simultaneously using only one unit. Salient features: state-of-the-art microcontroller technology; zero-crossing time-measurement to ensure finer accuracy; fastest sampling rate between successive measurements; 4-digit display to provide adequate resolution; operating range 160- 270 v ac; other operating voltages - 110 v ac and 440 v ac available on demand; auto ranging; and life time memory retention/back up.
