High specification fully waterproof (to IP67 standard) portable dissolved oxygen meter for field and laboratory use. The new and improved HI 9146 meter measures and displays O² from 0 to 300%, 0 to 45 mg/L and temperature from 0 to 50°C.
Results are microprocessor controlled and displayed on a large easy to read LCD screen which shows dissolved oxygen and temperature simultaneously. Dissolved oxygen readout can be selected in ppm or % saturation.
Calibration is automatic in 100% saturated air by simply pressing the CAL button. The meters are calibrated and ready to use in a matter of minutes. Auto-calibration eliminates the need to use a screwdriver or other devices to adjust the reading. Additional compensation for salinity (up to 80 g/l) and altitude (up to 4,000 m) can also be applied by the user.
The HI-9146 meter is supplied with DO probe HI 76407/4F with 4m cable, 2 spare membranes, 30 mL of electrolyte solution HI 7041S, batteries, rugged carrying case and instructions.
