Dissolved oxygen measurement technology has advanced from electrochemical sensors, such as polarographic and galvanic, to luminescent-based, optical sensors. YSI optical DO sensors are non-consumptive, meaning oxygen is not consumed during the measurement. As a result, there is no flow dependence or stirring required with ODO, allowing for the most accurate readings in the field.

Advantages over electrochemical sensors include:

• Higher accuracy with no stir dependence
• Less drift over time; holds calibration longer
• Less maintenance; no membranes or electrolyte

Real-Time Salinity Compensation

With an integral conductivity module, the ODO/CT probe assembly enables the ProSolo to automatically compensate DO mg/L measurements for changes in salinity. The 4-electrode conductivity cell, designed for rugged field performance, is easily cleaned and requires minimal maintenance.

ProDIGITAL Smart Sensors

In addition to utilizing the most advanced DO sensing technology, the ProSolo incorporates smart sensor technology that enables sensors to be automatically recognized by the handheld. Additionally, DIGITAL sensors store calibration data, so probe assemblies can be swapped between handhelds without the need for re-calibration.

Provides Years of Sampling for All Field Conditions

The ProSolo handheld meets the demands of true field work with a rugged, waterproof case (IP-67 rated) and a military-spec (MS) cable connector. Rigorously drop tested from all angles, the handheld features a 3-year warranty, while a 2-year warranty is included with the probe assembly and ODO Cap.

Advanced Data Management

ProSolo includes KorDSS Software, a powerful data management program for easy 2-way communication between the meter and a PC. A unique data backup feature allows for the export of data to a USB flash drive (included) in csv format without having to connect to a computer.
