Overview
The YSI Pro20 is a handheld dissolved oxygen and temperature meter ideal for use in the lab or field. Utilizing YSI's durable MS (Military Spec) cable connector, the instrument can accept rugged field sensors or a self-stirring lab BOD sensor. To meet the needs of various applications, cables are bought separately in lengths from 1 to 100 meters. The included cable management kit even makes the use of long cables easy and convenient.

One Touch Cal
The Pro20 is YSI's first dissolved oxygen instrument to offer a convenient "One Touch Cal" feature for air calibrations. This unique feature, along with others like user-replaceable sensors, simplifies operation and saves time and money. The YSI Pro20 is completely waterproof, withstands 1-meter submersion and has an industry-leading 2-year cable warranty making it field-worthy.

Questions & Answers

Can the Pro20 interface with a PC via a Pro Plus communications saddle?

No. Connecting the Pro20 to a communications saddle may cause the device to behave erratically.

What cables are compatible with the Pro20 dissolved oxygen sensor?

The YSI Pro20 is compatible with the Pro20 cable assemblies and the ProBOD probe. The field rugged cables incorporate a temperature sensor are available in lengths of 1, 4, 10, 20, 30, and 100 meters. The cables are compatible with both the 2002 galvanic and 2003 polarographic sensors. The ProBOD probe has 1 meter cable and comes with a built in dissolved oxygen and temperature sensor.

Does this meter store my data measurements?

The Pro20 dissolved oxygen meter can store up to 50 data sets on its internal memory for later viewing.

Which electrochemical DO sensor doesn't require warm-up after powering on the meter?

The YSI Galvanic dissolved oxygen sensor requires less warm up time than the Polarographic sensor due to the fact that the probe is always considered active (charged) while the meter is powered off.

Hypoxic Conditions in Lake Erie Impact Yellow Perch Population

Yellow perch are a species central to the culture and economy surrounding Lake Erie. With the largest commercial fishery and a prolific sportfishing industry, Lake Erie's yellow perch are a treasured study subject for environmental scientists. Daily bag limits and other public wildlife regulations rely heavily on the work of scientists like Ann Marie Gorman, one of the Fisheries Biologists responsible for coordinating ODNR ’s Central Basin Bottom Trawl Survey. The survey, ongoing since 1990, conducts seasonal assessments of the bottom fish community in Erie. It aims to index annual recruitment and catch-at-age of yellow perch.

Watershed groups handing tech to volunteers for better citizen monitoring

Watershed protection groups across the country are collecting water quality data on waterways that might otherwise miss out on monitoring entirely. Some have found that, despite small staffs, they can compile more high-quality data by putting water quality sensors and other professional scientific instruments in the hands of volunteers. For organizations like the Santa Barbara Channelkeeper, the reasoning for equipping volunteers with electronic handheld meters is clear: "We really want the data that we're collecting to be utilized," said Ben Pitterle, director of the group's watershed and marine program.

Researchers pioneer continuous groundwater quality monitoring in Ontario

As a graduate student in Ontario, Jana Levison manually sampled groundwater wells in a hay field for a week straight. Now an assistant professor in the University of Guelph's School of Engineering, Levison is investigating how a new generation of water quality sensors can move the science forward while cutting the labor back. Levison said her doctoral work in a crystalline bedrock aquifer showed monthly variations in nitrate — a common groundwater contaminant often sourced to intensive agriculture — and daily variations in E. coli. Those short-term changes got her interested in watching groundwater in a more detailed manner. "Now we have the equipment that we can do that," Levison said. That equipment includes YSI's EXO multi-parameter sondes and Satlantic's SUNA nitrate sensor.
