Otek’s HI-Q 121 is a bar graph meter that was created as a byproduct of two of our most popular units the HI-Q 119 and the HI-Q 120. Using the hardware from the HI-Q 119 and altering the casing from the HI-Q 120, we are able to present a slimmer meter that maintains its Seismic, EMI, RFI, and SV&V qualifications. This bar graph was particularly designed to make the switch from the old analog technology to new technology as seamless and cost efficient as possible. Input linearization including polynomials, X-Y tables (TC & RTD), flow calculations, and a variety of other mathematical functions make this digital panel meter an ideal tool for process monitoring and automation. With an interchangeable faceplate the bar graph can be customized to display a wide range of variables and scales, including watts, volts, amps, RPM, percent or any sensor output. The HI-Q121 brings color to the instrument panel or control room with up to two 51-segment LED arrays that allow range based control of the color displayed.
