The YSI 6130 provides accurate, in situ measurement of Rhodamine WT in fresh, brackish, and sea water, as well as in stormwater and wastewater. The YSI 6130 Rhodamine WT Sensor rejects turbidity and chlorophyll interference. Measurement accuracy is further enhanced through correction for the effects of temperature.
The YSI 6130 sensor can be used in combination with those YSI sondes that have optical ports - 600 OMS, 6820, 6920, 6600, 6820 V2, 6920 V2, or 6600 V2 - and a YSI 650 MDS handheld display-logger. Make surface as well as vertical profile measurements. In addition, the YSI 6130 in combination with one of the YSI data logging sondes can be used for unattended continuous monitoring or integrated with data collection platforms for real-time data acquisition.
- Range: 0-200 ug/L
- Resolution: 0.1 ug/L
- Accuracy: +/-5% reading or 1 ug/L, whichever is greater
- Warranty: 2 years
Install the 6130 sensor in the center port, seating the pins of the 2 connectors before tightening. Tighten the probe nut to the bulkhead but be sure to not over tighten.
A large amount of turbidity is required to affect the readings. (100NTU will read 3Ug/L). If measuring in a highly turbid environment, an independently determined turbidity reading may want to be taken to allow for compensation.
In The News
Until the advent of in situ rhodamine WT measurement systems, dye fluorometry hydrologic measurements were performed by the analysis of multiple samples physically extracted from the water body as the dye plume was naturally dispersed. Most of these investigations are performed using fluorometers designed for in vitro and pump-through measurements.
Although these methods can produce accurate hydrologic data, they are resource-intensive, significantly vulnerable to human error and other natural phenomenon. They also necessitate the field deployment of personnel throughout the duration of the study. The recent employment of in situ measurement systems has accentuated the limitations of in vitro and pump-through methods for performing these studies.Read More
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution.
Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up.
“This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.Read More
In 2012, for maybe the first time, Lake Superior got scummy.
Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.
It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms.
But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae.
Not the usual suspects
The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.Read More
