SDW Series digital point Wenyi, temperature measuring instruments, imports LSI chips and high-precision temperature sensing element, it has a high degree of interference immunity, LCD liquid crystal digital displays clear, accurate readings, low power consumption fast response time, site construction suitable for a variety of construction projects temperature, and the temperature probe can be measured with the use of a variety of material temperature. Such as: gas, liquid, fluid, mixing matter and granular materials; conjunction with embedded temperature line can be measured within the mass concrete temperature and winter construction concrete temperature. * Technical parameters Measuring range: -50-150 ℃ Resolution: 0.1 ° C Temperature measurement accuracy: ± 0.5% of embedded type temperature line: temperature probe: temperature probe plugs, wires, handle and outer diameter φ5mmX220mm metal tubing, tube front-end package temperature sensor suitable for measuring the material and clinker temperature. Temperature line: embedded temperature line made by the plugs, wires and temperature sensor suitable for measuring the internal temperature of concrete, each temperature line can measure temperature, arbitrary arrangement of temperature measurement point in the construction. For to facilitate stratified temperature measurement each temperature line plug affixed with the corresponding length specification label. Temperature line specifications: 0.5m, 1m, 1.5m, 2m, 2.5m, 3m, 3.5m, 4m, 4.5m, 5m and other specifications can be customized! Usage: 1. Plug the temperature probe with a the host temperature probe measuring the temperature of the material inserted into the host socket, press the power switch, the temperature probe metal rod inserted into the measured object, the insertion depth of not less than 1/2 of the length of two minutes The left and right on the host reads temperature data. Affect the service life of mixture temperature measurements, in order to avoid the excessive impact of a hard object in the temperature probe in the mixture can be in Mixture holes with a metal stick, then the temperature probe is inserted in the hole temperature. Temperature probe should wipe clean after each use. 2. Host temperature line measuring temperature in mass concrete construction temperature measurement program to determine, based on the number of measurement points and depth of the chosen length specifications suitable temperature line, for example: the actual measurement points depth 0.2m ~ 0.3m, the choice of specifications temperature line is 0.5m; actual measurement points deep 2.5m to 2.8m, the choice of specifications for 3m temperature line, inferior race, and so on. Embedded reinforced rod for supporting material available at the time, the wire is tied to a support, in accordance with the longitudinal temperature measurement point distance between the temperature sensor with supporting material should be done insulated. In pouring concrete, will be tied up the temperature line of the support was implanted in concrete, the temperature sensor is in the location of the measurement points, plugs remain in the outside of the concrete and with a plastic cover to avoid moisture and kept clean. For ease of operation, the length of stay outside the wire should be more than 20cm. Temperature, press the main power switch, and plug the wire is inserted into the host socket, host on the display to show the temperature of the corresponding measurement points.
