INEXPENSIVE THERMISTOR SENSORS FOR TEMPERATURE MEASUREMENTS IN ORGANIC SOILS
JAMES A. CAMPBELL, LOUISE FRASCARELLI · Canadian Journal of Soil Science · 1981
Thermistors were incorporated in stainless steel tubular probes and in CPVC epoxy-filled pioe for accurate periodic and continuous in situ measurements of temperature in organic soil. Temperature can be measured with ± 0.1 °C with portable analog meters and ± 0.01 °C with digital meters.
