What must be done to the concrete around the temperature measuring device once it is submerged?

When a temperature measuring device is submerged in concrete, gently pressing the concrete around the device is important to ensure that it has proper contact with the surrounding material. This enhances the accuracy of the temperature readings, as air pockets or loose concrete can create insulation errors, leading to inaccurate data collection. The materials need to be in intimate contact so that the thermal properties of the concrete can be accurately measured by the device.

Care must also be taken to not disturb the device excessively, which could affect its positioning or function. This action ensures that the temperature measuring device is securely positioned, minimizing the risk of displacement and ensuring reliable temperature readings during the curing process or any other evaluations involving temperature monitoring.
