Temperature String

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


Titanium Thermistor

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

Marine-Grade Cable

Nodes are integrated using marine-grade cables with braided Kevlar core and epoxy seal. Strings are available in multiple standard increments.

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.

Data Output

Temperature data is transmitted on a RS-485 Modbus RTU string bus for integration with data loggers and SCADA systems.


Strings terminate in a NexSens UW plug and receptacle connector, allowing additional sections or sensors to be added as required.
