Thermistor chains

Thermistor chains for temperature profiles, up to 30 nodes, 200 m cable, ±0.1 °C accuracy.

Sensor · SDI-12 profile

Thermistor chain

Up to 30 thermistor nodes on a single chain. Continuous temperature profiling at multiple depths, for stratification analysis in lakes, reservoirs and permafrost boreholes.

Configurable node spacing, cable lengths up to 200 m. The connected logger sends threshold alerts via SMS or e-mail.
