Application Note: Small Team Saves Big Hassles With The Professional Plus Multiparameter Instrument

The lab team at Greene County Sanitary Engineering in Beavercreek, Ohio, has plenty to do in the field as well as back at the laboratory, so doing a couple of things at once saves them time and money. The crew conducts monthly sampling on the Little Miami River, a State and National Scenic River, and Massie Creek to monitor the county's two wastewater treatment plants and comply with monthly and quarterly National Pollutant Discharge Elimination System (NPDES) reporting requirements.

Grab samples are taken at each site and analyzed for ammonia, total Kjeldahl nitrogen (TKN), nitrate, nitrite, phosphorus, hardness , metals , Fecal coliform, oil & grease and mercury. Additionally, on-site, laboratory technician Teresa Shinkle and her team take measurements of temperature, dissolved oxygen (DO) and pH at each location.

In the past, Shinkle and her colleagues carried separate YSI meters for pH and DO, she notes. Now they use the YSI Professional Plus handheld multiparameter instrument, which allows them to measure pH, DO and temperature with one quick, reliable instrument.
