Overview

HI 9146 is a microprocessor-based, water-resistant, dissolved oxygen meter with automatic calibration and an extended range to measure up to 300% or 45 ppm(mg/L). This instrument also allows altitude compensation up to 4000m.

Dissolved Oxygen measurements are displayed in parts per million (ppm=mg/L) or in %saturation.

Temperature range is indicated in Celsius from 0 to 50°C with 0.1 resolution. The HI 9146 also allows manual compensation of salinity values up to 80 ppt (g/L).

A HOLD button allows the user to freeze the reading on the LCD for later retrieval.

HI 9146 can be powered with batteries or 12 Vdc adapter.
