HI 9024 is microprocessor-based pH meter in waterproof casings.

HI 9024 measures pH and temperature. Both meters are housed in rugged, waterproof, ABS casings that are built to last.

The Auto-Instruction feature guides the user step-by-step through the calibration process with graphic symbols. The automatic calibration procedure is simple and quick and can be performed at 1 or 2 points selected from 5 memorized buffers: pH 4.01, 6.86, 7.01, 9.18, 10.01. A stability indicator assures a correct calibration. Both meters also feature automatic shut-off to save battery life.
