Why Buy From Fondriest?


In response to the need for accurate, in situ measurement of Rhodamine WT for water and pollutant tracing, YSI has developed the 6130 Rhodamine WT Sensor. The 6130 is a fouling-resistant, wiped sensor designed to seamlessly integrate - using no external interface hardware - with all YSI sondes that contain an optical port.

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.
Notable Specifications:
  • Range: 0-200 ug/L
  • Resolution: 0.1 ug/L
  • Accuracy: +/-5% reading or 1 ug/L, whichever is greater
  • Warranty: 2 years

Questions & Answers

| Ask a Question
How do I install my 6130 sensor?
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.
Will high turbidity affect my readings?
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.

Rhodamine Dye Tracer Systems

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.

As Arctic Permafrost Thaws, Northernmost Lakes Brown

More than 250 million years ago, massive volcanic activity in the region of what is now Siberia caused “The Great Dying,†a colorful name for the Permian mass extinction that wiped out most of the life on Earth at the time. Once the volcanic activity finally calmed down after a respectable one million years, about 96 percent of life in the ocean and 80 percent of life on land was gone. About 500 gigatons of carbon were left behind in that region, and as the Earth cooled, that carbon was sealed in the Permafrost that covers much of Siberia today. Permafrost is simply ground that stays frozen at or below 0° Celsius (32° Fahrenheit) all of the time. It does not necessarily contain ice; as long as it remains frozen solid, even completely dry ground is permafrost.

Volunteer Water Quality Monitoring Networks at the Heart of Citizen Science Movement

Lately, citizen science initiatives have been getting noticed by laypeople and mainstream media outlets. As everyday people become aware of ways they can get involved in actual scientific research, more of them are doing so—especially teachers and parents working with children. But this citizen science wave isn't actually a new thing. It has been growing outward from its core in volunteer water quality monitoring networks for years. Around the country, volunteers have been quietly monitoring the water quality in lakes, streams, rivers, marshes, and other surface waterways for decades. These highly successful programs have been supporting better water quality in communities across America, and in doing so have also formed the heart of the modern citizen science movement.
