Dissolved Oxygen (DO)

Hanna Professional Multi-Parameter Waterproof Meter pH / ORP / EC / DO ²⁵

$ 1,770.99 USD

It is a portable multiparametric meter with waterproof logging capability that monitors up to 12 water quality parameters, 6 measured and 6 calculated. The multisensor probe with a microprocessor allows measurement of key parameters such as pH, ORP, conductivity, dissolved oxygen, and temperature. The probe digitally transmits readings to the meter, where data points can be displayed and recorded. The use of digital communication enables noise-free data transfer up to a length of 100 meters. The complete system is easy to set up and user-friendly.

The meter features a backlit dot matrix display with on-screen graphics and the ability to automatically adjust digit sizes based on the number of selected parameters. Each measured parameter is fully configurable.

Designed to withstand demanding environments, it is the ideal solution for field measurements in lakes, rivers, and oceans. The meter complies with IP67 standards, and the multisensor probe complies with IP68 standards.

YSI ProSolo Optical Dissolved Oxygen/Temp Meters

$ 1,921.50 USD

The ODO/T probe assembly pairs with the ProSolo handheld to form a complete sampling system.

With integral digital sensors, the plug-and-play ODO/T minimizes the time spent setting up the instrument. Pro DIGITAL technology allows the handheld computer to automatically recognize connected sensors, so there is no need to tell the instrument that it is connected.

Optical dissolved oxygen (ODO) technology is non-consumptive, meaning that no oxygen is consumed during the measurement. Flow dependence is non-existent and agitation is not required, resulting in the most accurate DO measurements available from a probe. The ODO sensor is not susceptible to interference from other gases, shifts less and maintains calibration longer than membrane-covered sensors. Maintenance is very simple with a single optical cover that is good for at least two years.

ProSolo Handheld features an easy-to-read color display, large capacity memory, intuitive interface, rechargeable battery and powerful data management software (KorDSS) for a powerful and convenient sampling experience. Excellent for surface water, groundwater, coastal/estuarine, aquaculture and wastewater applications!
