ND-TP Soil Temperature Profile Sensor
What is the ND-TP? The ND-TP is a high-precision multi-element temperature profile probe with up to 16 freely-positionable silicon temperature sensors along a stainless steel string up to 250 m long. Designed for temperature profiling in glaciers, lakes and oceans, permafrost monitoring in soil and rock, dike and dam monitoring and general soil temperature studies connected to the yDoc ML-525 datalogger.

Applications
Where the ND-TP is used
Glacier & permafrost
Long cable strings down boreholes for cryosphere and permafrost research.
Lake & ocean profiles
Vertical temperature profiles for limnology and oceanography studies.
Dike & dam monitoring
Temperature profiles for seepage detection and structural health monitoring of earthworks.
Soil temperature studies
Multi-depth soil temperature for agronomy, climate research and frost forecasting.
Integration
Powered by the yDoc ML-525 datalogger
The ND-TP connects directly to the yDoc ML-525 datalogger. The yDoc powers the sensor, schedules measurements, stores readings locally and transmits them to the Sensor-Online platform via 4G/LTE-M, NB-IoT, LoRaWAN, satellite or Ethernet — with up to 10 years of battery life.
