The HM-500 combines several water-quality measurements in a single display. Large numerals and clearly separated reading areas give each parameter a distinct place, with the controls grouped along the bottom of the screen.

A gray silicone sleeve frames the black front fascia. Rounded edges and a narrowed waist define the housing, while the rear integrates a folding stand for benchtop use. The monitor also supports wall-mounted and portable use.
