The Thermo Scientific Orion Lab Star DO113 Dissolved Oxygen Bench Meter is ideally suited for laboratories with users of varying levels of technical expertise and who require a simple-to-calibrate and use meter for routine dissolved oxygen testing. Scientists have trusted Thermo Scientific Orion Lab Products for over 60 years to provide them with accurate and reliable analytical testing instruments in the lab and in the field.

Measure dissolved oxygen as percent saturation, concentration in mg/L or concentration in ppm simultaneously with temperature using the Orion Lab Star DO113 DO Bench Meter. To enable comprehensive measurement capabilities, measure dissolved oxygen in a range of 0.0 to 300.0 % saturation, 0.00 to 30.0 mg/L or ppm and measure temperature in a range of -5.0 to 105.0 °C or 23.0 to 221.0 °F.

For proficient SOP compliance, perform 100% saturation, 0% saturation and custom concentration calibrations for dissolved and one-point temperature adjustment calibrations.

Featuring a large, backlit display for easy viewability and small footprint to save bench space, this dissolved oxygen meter is ideally suited for simplified, budget-friendly lab testing. Use the onscreen stabilizing and ready indicators to help identify when DO meter readings are complete.

View active dissolved oxygen and temperature calibration logs with date and time stamp to ensure accurate, reproducible measurements. Record key measurements using the 500-point data log with date and time stamp. Output data logs and calibration logs to a printer or computer for long-term data storage.

Crystal Clear Problems: Impacts of Water Transparency in Aquatic Ecosystems

From crystal clear alpine lakes to muddy rivers and boggy swamps, water transparency is an easily observable water quality parameter to anyone who takes a few moments to peer into the (sometimes) murky depths. Water transparency varies dramatically based on the location of bodies of water among different watershed environments, but it can also change quickly due to a variety of internal and external factors. At Miami University (OH), the Global Change Limnology Lab explores the many ways that water transparency impacts aquatic ecosystems. Operational for nearly 20 years, the lab trains undergraduate and graduate students and has conducted work from the midwest Great Lakes to Alaska, South America and New Zealand.  The Global Change Limnology Lab, headed by Dr.

Lake Malawi: A Treasure to Protect

Lake Malawi (also known as Lake Nyasa and Lake Niassa) doubles as a Rift Valley Lake and one of the seven African Great Lakes. Due to its unique biodiversity, it’s a great place to conduct limnological studies. Harvey Bootsma is a professor for the School of Freshwater Sciences at the University of Wisconsin-Milwaukee and has had an interest in limnology ever since he was a kid. Bootsma fondly recalls summer vacations to Georgian Bay, Ontario, “I probably spent as much time in the water as I did out of it.” He continues, "I remember telling myself, ‘I’m going to get a job where I can stay here all the time.’” While Harvey didn’t end up working on Georgian Bay, he was offered a job working on Lake Malawi. He continued working there while completing his Ph.D.
