AELAB 980 Laboratory Dissolved Oxygen Meter – Precision DO Measurement for Water Analysis

The Laboratory Dissolved Oxygen Meter 980 is a high-precision instrument designed for measuring dissolved oxygen concentration and % saturation of oxygen in water. It offers 1 or 2-point calibration using air-saturated water or a zero-oxygen solution, ensuring accurate results. The meter compensates for salinity and barometric pressure, making it ideal for diverse environmental conditions.

With selectable units like mg/L, ppm, mmHg, and kPa, the 980 meter provides flexibility in measurement reporting. Automatic Temperature Compensation (ATC) ensures stable readings across varying temperatures. The Auto-Hold function locks in stable readings, while the stability indicator ensures only reliable measurements are recorded.

Users are reminded to regularly calibrate via the Calibration Due Reminder. The expanded memory can store up to 100 data sets, which can be transferred to a computer via the USB interface for further analysis. The setup menu allows customization of up to 9 parameters, including calibration points, resolution, and stability criteria. The meter also features a reset function to restore factory settings for ease of use.

Included are a dissolved oxygen probe, membrane cap, electrolyte solution, electrode holder, and power adapter, making the 980 meter a comprehensive and reliable tool for laboratory dissolved oxygen measurements.
