Measuring 1.6 m in length, the Earth Thermometer is a needle probe effective for short or long-term deployments. It is ideal for applications in geothermal, geophysical, and soil science sectors.
The storage of data can be extended up to a year and can be re-used several times based on the probe’s robust, durable construction. Temperature readings are measured and recorded at 30 cm and 110 cm beneath the surface.
The President of Hot Dry Rocks, Graeme Beardsmore said that the Earth Thermometer is a complementary piece of equipment added to the geophysicist’s toolbox. Owing to its simple deployment and reusable capability, this versatile device will be popular among the global geophysical rental equipment companies.
This device will enable geophysicists to investigate hydrothermal resources to volcanologists monitoring fumaroles. It has been designed for monitoring ground temperature within and the area surrounding thermal hot springs, geothermal reservoirs, volcanoes, buried infrastructure or radioactive waste. This device has wide applications in climate monitoring, coal seam fires, smart grid, hydrology, agriculture, and soil science.
Hot Dry Rocks is commercializing this innovative product, particularly targeting the Japanese market.
According to Lawrence Molloy at HDR’s Technologist, the passive and non-invasive nature of this device makes it ideal for deployment in Japan for exploring national parks and adjacent to their onsens. This device ensures long-term monitoring based on larger geothermal developments within the onsen market.
The device units can be used in transects, pairs or arrays, as it has been designed to distinguish temperature drift of the ground between two locations. Data recording can be carried out in selected intervals and stored at the surface in solid state memory. Different thermometer models ensure precision of 0.1, 0.01 and 0.005C.
