TS210 Temperature String

The NexSens TS210 Temperature String provides high precision measurements for profiling in lakes, streams, and coastal waters.

Features

Titanium Thermistor

Each node features an integral titanium thermistor secured and epoxied in a protective housing for underwater deployments.

High Accuracy

Each sensor is accurate to +/-0.075 C. The exposed titanium thermistor makes direct contact with water, allowing readings to stabilize within 60 seconds.

Q&A

What is the difference between the T-Node FR and the TS210?

The TS210 is a more affordable and generally more robust temperature string, as the cable is epoxied to both ends of the thermistor in place of connectors. The connectors on either end of the T-Node FR sensor allows the end user to add, remove, and reconfigure the string themselves, making it a more flexible solution.

What are the maintenance requirements of the TS210 temperature string?

Temperature strings require minimal maintenance. Remove any bio-fouling with a cloth or soft bristled brush and soapy water. NexSens temperature strings hold their calibration for the life of the sensor, so they do not need to be recalibrated. In the offseason, sensor strings should be stored in a cool, dry place.

Will freezing conditions damage a TS210 sensor?

NexSens does not recommend deploying the thermistor string in any conditions that pose a risk of freezing, as it is outside of the measurement range and can be detrimental to the sensor. The TS210 accurately reads water temperatures no lower than 32° F (0° C), and the PVC housing can crack and fail from the stress of freezing and thawing.

How much assembly is required for the TS210?

It is recommended that thermistor string be clamped in place along a suspension line when deployed. We offer thermistor string clamps and vinyl-coated stainless steel mooring lines as optional accessories.

How is the sensor string installed?

The thermistor string is most commonly deployed on floating platforms such as data buoys. It can also be suspended in water storage tanks, deployed horizontally to measure stream temperatures, and more.

How accurate are the sensors on the string?

The thermistor string accuracy is ±0.075℃.
