Portable Dissolved Oxygen Meter Kit Apera DO 850

The Portable Dissolved Oxygen Meter Kit Apera DO 850 is a portable and affordable dissolved oxygen meter kit designed for reliable DO measurement in field and laboratory settings. It offers accurate, quick readings for water quality applications such as aquaculture, wastewater treatment, and environmental monitoring. While it features a straightforward interface and essential functions, it still delivers high-precision performance and advanced compensation technologies for reliable data.

Although the DO850 is more simplified than higher-end models, it retains professional-grade core features like dual-point calibration, automatic compensation, and versatile unit display.

Features

Accurate and Flexible DO Measurement

The DO850 covers a measurement range from 0 to 20.00 mg/L (ppm) and 0 to 200.0% oxygen saturation, making it suitable for a wide variety of applications. Users can select either 0.01 or 0.1 mg/L resolution and 0.1 or 1% saturation, depending on their accuracy needs.

Reliable Accuracy with Compensation

The instrument provides ±2% reading or ±0.2 mg/L accuracy, whichever is greater. This level of performance is supported by automatic temperature and barometric pressure compensation, ensuring stable readings even as environmental conditions change.

Dual Calibration Capability

For consistent accuracy, the meter supports two-point calibration: 100% oxygen saturation and 0% oxygen. This makes it easier to maintain precision in both low and high DO environments.

Compact Design with Essential Functions

The DO850 includes automatic hold, which allows users to lock in stable readings without manual effort. However, unlike advanced models, it does not feature date/time display, data logging, or USB connectivity—making it ideal for users who need simplicity without compromising measurement quality.
