Abstract

The invention relates to an electronic digital-display speed-reading geothermometer, relating to a geothermometer and aiming to solve the problems that the measurement accuracy of the geothermometer is poor, long temperature equilibration time is needed to guarantee the measurement accuracy and the measurement efficiency is low. The tail end of a temperature-sensing probe head is fixed at the front end of a probe pin through a thermal insulation sealing ring, a handle is fixed at the tail end of the probe pin, a digital display circuit is fixedly arranged on a handle and comprises a control module and a display screen, and the display signal input end of the display screen is connected with the display signal output end of the control module; and the temperature signal output end of the temperature-sensing probe head is connected with the temperature signal input end of the control module. The electronic digital-display speed-reading geothermometer is suitable for measurement of the temperature of the shallow soil below the ground surface or solid substances on the surface.

Description

technical field [0001] The invention relates to a ground thermometer. Background technique [0002] In scientific experiments and production activities, it is often necessary to measure the temperature inside the shallow soil or surface solid matter below the surface. The traditional method is to use a group (5 pieces) of right-angle glass mercury geothermometers, which are respectively buried in the soil of 50mm, 100mm, 150mm, 200mm and 250mm. However, this glass mercury geotherm has the following disadvantages: 1. It takes a long time for temperature equilibration to ensure the accuracy of temperature. 2. Since the measurement accuracy of the glass mercury geothermometer is generally 1 degree Celsius, the accuracy is low, and it is difficult to meet the requirements of scientific research; 3. It is not convenient for storage and transportation. Because it is made of glass, it requires a large space and anti-corrosion in transportation and carrying. Damage treatment, espe...
