Description
The HI9147 portable dissolved oxygen meter provides accurate DO measurements from 0.00 to 50.00 mg/L (ppm) and 0.0 to 600.0% saturation with ±1% of reading accuracy. It utilizes a galvanic probe with a silver cathode and zinc anode housed in an electrolyte solution behind a PTFE membrane. Calibration is simple and flexible, offering manual calibration in saturated air and automatic one or two-point calibration at 100% and/or 0% saturation. Automatic temperature compensation from 0 to 50°C, along with adjustable salinity (0–51 g/L) and altitude compensation (0–4000 m), ensures reliable readings across diverse environments.
Built for durability and ease of use, the HI9147 includes an auto endpoint feature that freezes the display once a stable measurement is reached. GLP functionality allows users to recall calibration data for documentation and quality control. The replaceable, pretensioned PTFE membranes feature a convenient screw-cap design for easy maintenance. Supplied complete with probe, membranes, electrolyte solution, batteries, and a rugged carrying case, the HI9147 is ready for immediate field deployment.
