Premium Portable Optical DO Meter Apera DO 8500

Premium Portable Optical DO Meter Apera DO 8500

The Premium Portable Optical DO Meter Apera DO 8500 is a high-performance portable optical dissolved oxygen meter designed for professionals who require quick, accurate, and hassle-free DO measurement in both field and laboratory environments. Utilizing advanced optical sensor technology, it eliminates the need for membranes and electrolyte replacement, thus offering long-term stability and minimal maintenance. Its premium build and intelligent functions make it ideal for water quality professionals in aquaculture, environmental monitoring, and wastewater treatment.

Thanks to its multiple compensation functions and high data capacity, the DO8500 ensures reliable results even in challenging testing conditions.

Features

Wide DO Measurement Range

The DO8500 can measure dissolved oxygen from 0 to 20.00 mg/L (ppm) or 0 to 200% oxygen saturation, covering a broad spectrum of applications. With selectable resolutions of 0.01 or 0.1 mg/L, and 0.1 or 1%, it allows users to adapt the display for either precision or readability depending on the task.

High Accuracy with Intelligent Compensation

It delivers accuracy of ±2% of reading or ±0.2 mg/L, whichever is higher, ensuring consistent performance. Furthermore, the instrument features automatic temperature, barometric pressure, and salinity compensation, which are critical for real-time environmental conditions. While temperature and pressure compensation are automatic, salinity can be set manually or automatically, offering flexibility in diverse testing situations.

Dual-Point Calibration for Reliable Accuracy

The DO8500 supports two calibration points: oxygen saturation (100%) and zero oxygen (0%), which provide an accurate baseline and optimal linearity for full-range DO measurements.

Temperature Measurement and Compensation

Besides DO, the meter measures temperature from 0 to 50.0°C with 0.1°C resolution and ±0.5°C accuracy, ensuring precise compensation during DO testing.

User-Friendly Features

To enhance workflow and data integrity, the DO8500 is equipped with:

• Automatic Hold to freeze stable readings

• Date and Time display for traceability

• 500-set data memory for extensive logging

• USB output for easy data export to PC
