Small make up teach you how to test industrial V Marine thermometer

V Marine thermometer, intuitive display temperature is convenient, safe and reliable, long service life and can fast reading. The product is used for pipelines, chemical equipment, used to test surface temperature, and pipe professional thermometer. V Marine the structure of the thermometer is by the glass rod, the upper and lower body of three parts. Is the upper aluminium by polishing or sandblasting and anodic oxidation into gold, to uncover her nakedness for copper, when high temperature iron material is qualitative. SIKA thermal components in filling mercury thermometer. SIKA thermometer in blue or red organic thermal fluid filling. Above 300 c, filled with mercury. V Marine thermometer body length is generally have three, respectively is 110 mm / 150 mm / 200 mm, installation method has two kinds of straight and curved type; Inspection timing a v-shaped Marine temperature and accuracy: ( In second class standard thermometer for standard, incubator as testing equipment. ） Check point should be evenly distributed throughout the entire measuring range, shall not be less than three, should include zero zero, the permissible error of & plusmn; 1. Second, the visual inspection: appearance ( Visual) Visible parts have no obvious blemishes, scratch and burr, no broken glass rod fluid or hang drop phenomenon. Glass rod calibration and shell logo printing should be clear and accurate cannot have an impact on the phenomenon of reading. Three, packing inspection: V Marine thermometer must set the appropriate bubble bag or plastic bag, and put the corresponding outer. Carton is moderate, good shockproof material, to avoid glass rod broken in transit. V Marine the working principle of the thermometer is the use of liquid temperature measuring principle of heat bilges cold shrink effect: when the temperature changes, the glass ball in the liquid volume expansion or contraction, will happen to change into the liquid column height in capillary, which indicates the temperature change. Finally tell you: in order to measure the accuracy and the accuracy of reading and different temperature, choose a different thermometer. By first estimated by measuring the temperature of the liquid or gas to select suitable thermometer, temperature is suitable for measuring the size of the original site requirements, so as not to cause the damage of the thermometer.
