Method of use for electronic temperature measuring instruments for concrete
1. Use the host and temperature measuring probe to measure the material temperature
Insert the plug of the temperature measuring probe into the host socket, press the power switch, insert the metal rod of the temperature measuring probe into the measured object, with a depth of not less than 1/2 of its length, and read the temperature data on the host for about two minutes. When measuring the temperature of the mixture, to avoid excessive impact between the temperature measuring probe and hard objects in the mixture, which may affect its service life, a metal rod can be used to reserve a hole in the mixture, and then the temperature measuring probe can be inserted into the hole for temperature measurement. The temperature probe should be wiped clean after each use.
2. Usage method of electronic temperature measuring instrument for concrete: measuring the temperature of large volume concrete using a host and a temperature measuring line
After determining the construction temperature measurement plan, select a temperature measurement line with appropriate length specifications based on the number and depth of temperature measurement points. For example, if the actual temperature measurement point depth is 0.2m-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. Insulation treatment should be done between the temperature sensor and the support. When pouring concrete, the support with the temperature measurement wire tied should be implanted into the concrete. The temperature sensor should be at the temperature measurement point, and the plug should be left outside the concrete and covered with a plastic bag to avoid moisture and maintain cleanliness. 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 and insert the temperature measurement cable plug into the host socket. The temperature of the corresponding temperature measurement point can be displayed on the host display screen.
3. Usage method of electronic temperature measuring instrument for concrete: Using a host and temperature measuring line to measure the temperature of concrete during winter construction
When pouring concrete, temperature measurement holes should be reserved according to the winter construction temperature measurement plan, and one measuring rod should be placed inside each hole
Leave the plug of the temperature measuring wire outside the hole and cover it with a plastic bag to avoid moisture and keep it clean. When measuring temperature, press the power switch of the host and insert the temperature measurement cable plug into the host socket. The temperature of the corresponding temperature measurement point can be displayed on the host display screen. After each stage of temperature measurement, store the temperature measurement line for future use. The temperature measurement line can also be buried in concrete for one-time use, as shown in usage method "2".
4. Usage method of electronic temperature measuring instrument for concrete - Use of night temperature measurement reading and lighting function
When used at night or in a dark environment, pressing the host lighting switch will emit a light green background light on the LCD screen, making the reading clear and eye-catching.
