The HI9146 is a rugged, portable dissolved oxygen (DO) meter designed to provide laboratory precision and accuracy under harsh environmental and industrial conditions. Developed for measuring dissolved oxygen in water, wastewater, and environmental testing, this meter can also compensate for altitude and salinity.
Dissolved oxygen is a commonly measured parameter in aquaculture, wastewater treatment, environmental studies, and wine analysis. The HI9146 is a rugged, portable dissolved oxygen (DO) meter designed to provide high accuracy measurements whether in the field or in the lab. The meter features automatic calibration performed at one or two points in saturated air and/or zero oxygen solution.All readings are automatically compensated for temperature variations and can be frozen on the display upon stability using the auto-end feature. Salinity and altitude compensation are user adjustable based on the environmental conditions that are present. The HI9146 features a Battery Error Prevention System (BEPS) that detects when the batteries become too weak to ensure reliable measurements. The HI9146 portable DO meter is supplied complete and ready to use.
Order Information: HI 9146-10 is supplied complete with HI 76407/10F probe with 10 m cable, HI 76407A membranes (2), HI 7041S electrolyte solution (30 mL), batteries, instructions and rugged carrying case.
