Air/Water/Soil Temperature Sensor (H-377)

WaterLOG Air/Soil/Water Temperature Sensor (H-377)

If you are looking for accurate and reliable temperature data in stream, lake, well, ocean, waste water, soil and air applications, the Air/Soil/Water Temperature Probe (H-377) is your sensor. This reliable data acquisition probe measures air, soil, or water in temperatures ranging from -40° C to 80° C. The probe  is great for long-term field operation because it is calibration free, provides fast response and high accuracy.  Its sealed, corrosion-resistant, and non-conductive enclosure ensures durability in rugged environments. The Air/Soil/Water Temperature Probe is also compatible with the H-350 XL and H-500 XL data loggers.
