Basic overview and operation method of handheld concrete thermometer:
Measure the temperature of large volume concrete using a host and temperature measuring cable
After the construction temperature measurement plan is determined, appropriate length and specifications of temperature measurement lines should be selected based on the number and depth of temperature measurement points. For example, if the actual temperature measurement point depth is 0.2m to 0.3m, a temperature measurement line with a specification of 0.5m can be selected; The actual temperature measurement point depth is 2.5m-2.8m, and a temperature measurement line with a specification of 3m can be selected, and so on. When embedding, steel bars and other rods can be used as supports, and the temperature measurement line should be tied to the support according to the distance between the longitudinal temperature measurement points. The temperature sensor and the support should be insulated. When pouring concrete, insert the support with the temperature measuring wire tied into the concrete, place the temperature sensor at the temperature measuring point, leave the plug outside the concrete and cover it with a plastic bag to avoid moisture and keep it clean. For ease of operation, the length of the wire left outside should be greater than 20cm. When measuring temperature, press the power switch of the host, insert the temperature measurement cable plug into the host socket, and the temperature of the corresponding temperature measurement point will be displayed on the host display screen.
