TACH-IV Wide Range Non-Contact Tachometer Offered By Monarch

—Literature Available Monarch Instrument of Amherst, N.H., is offering free literature on the TACH-IV digital optical tachometer the company produces.

One of the widest speed measuring ranges of any portable non-contact tachometer and a simultaneous maximum hold capability are two of the unique features that make the Model TACH-IV digital optical tachometer one of the most versatile instruments ever available for the instrument engineer.

The TACH-IV's ability to measure measure speeds from 5 rpm to 500,000 rpm makes it suitable for every application throughout industry, from adjusting extremely slow variable speed drives, to checking motor and pump speeds, to measuring very high-speed turbines. The TACHIV's simultaneous maximum capability makes it also capable of capturing peak speeds, a feature particularly useful in setting speed governors of overspeed trip switches.

A unique self-test program that checks and displays key functions of the instrument is made possible by TACH-IV's micro-processor control, which also provides accuracy of .01 rpm, resolution of up to .0001 rpm, and a memory recall feature. TACH-IV is designed to provide convenient portable operation in its padded carrying case, or semi-permanent operation by means of the remote mounting and control feature provided.
