measurement The point depth is 2.5m~2.8m, and the temperature
measurement line with a speciïŹcation of 3m can be selected, and so
on. When pre-embedded, steel bars and other pieces can be used as
supports, and the temperature measurement line is tied to the support
according to the distance of the longitudinal temperature measurement
point. The temperature sensor and the support should be insulated.
When pouring the concrete, implant the support with the temperature
measuring wire into the concrete, the temperature sensor is at the
temperature measuring point, and the plug is left outside of the
concrete and covered 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 the temperature, press the
power switch of the main unit and insert the plug of the temperature
measurement line into the socket of the main unit, and the temperature
of the corresponding temperature measurement point can be displayed
on the main unit's display screen.
