Frost gauges and freezing gauges / J.A. Banner and R.O. van Everdingen. : En36-503/110E-PDF
"Several types of frost gauges to detect frost (temperatures at or below 0°C) and several types of freezing gauges to determine the occurrence and extent of soil freezing (conversion of soil moisture from liquid to solid) were designed and constructed. The multisensor electrical-resistance freezing gauges enable determination of the progress, with time, of freezing and thawing in both saturated and unsaturated soils. In the case of unsaturated materials, the use of temperature sensors or electrical-resistance or visual frost gauges makes it possible to distinguish between the resistance effects of freezing and those of drying of the soil. Computer-generated plots of resistance vs. depth and time are used in the interpretation of the data. Best results are obtained when freezing gauges with small electrode spacings, installed directly in the soil, are measured daily"--Abstract, p. v.
