Hanna HI764073 Dissolved oxygen probe with 4 m

Hanna HI764073 Dissolved Oxygen Probe with 4 m Cable

The Hanna HI764073 Dissolved oxygen probe with 4 m is a high-precision, multi-functional dissolved oxygen (DO) probe designed for use with compatible meters in demanding applications such as environmental monitoring, wastewater analysis, and biological oxygen demand (BOD) testing. Equipped with a 4-meter cable, this probe supports multiple measurement modes including DO, BOD, OUR, and SOUR, and features advanced automatic compensation systems for barometric pressure, temperature, and salinity.

Features

• Wide DO Measurement Range: Accurately measures dissolved oxygen from 0.00 to 50.00 mg/L or 0.0 to 600.0% saturation, suitable for a wide range of water quality testing scenarios.

• High Accuracy & Resolution: Offers ±1.5% of reading ±1 digit accuracy with 0.01 mg/L or 0.1% saturation resolution, ensuring precise data even in critical applications.

• Multiple Calibration Options: Supports automatic one or two-point calibration (0% and 100%) or manual entry for user-defined calibration values.

• Barometric Pressure Measurement: Integrated pressure sensor with automatic barometric compensation and one-point calibration capability from 450 to 850 mmHg.

• Broad Temperature Capability: Operates in extreme conditions with a range of -20.0 to 120.0°C, and offers calibration at one or two points within the full range.

• Multi-Mode Measurement: Capable of performing DO, BOD, OUR (Oxygen Uptake Rate), and SOUR (Specific Oxygen Uptake Rate) testing, making it ideal for environmental and wastewater laboratories.

• Automatic Compensation: Includes temperature, salinity, and barometric pressure compensation to ensure the highest accuracy across varying conditions.
