We all know the role of the thermometer is used to measure the temperature of the medium, the Marine thermometer is what? Marine thermometer is generally used in measuring the temperature of the engine block, cylinder, water warehouse. Today the instrument to introduce V Marine thermometer for everyone. This kind of Marine thermometer through long-term practice and innovation, by the vast number of users, in terms of quality and after-sales service perfect application and shipping industry. V Marine thermometer 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. SK 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. 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; A thermometer in blue or red organic thermal fluid filling. Above 300 c, filled with mercury. Timing must indicate: customer order in Marine temperature thermometer upper ( Calibration tube) Length, the probe length ( Including thread) The temperature range ( ℃ ℉ dual scale must indicate) , connecting thread, probe material.
