Industrial glass rod thermometer in industrial applications is mainly used for pipeline, petrochemical, power plants and Marine, etc. , the structure style in general as shown in the figure below: models: SKA types: Marine thermometer structure: radial type, screw tooth fixed materials: 1/2 BSP (metal case tooth head: Can be customized) The upper length: 110 mm ( Can be customized) Temperature range: 0 - 100C( Can be customized) Heat pipe: 50 mm ( Even the teeth) Accuracy: & plusmn; 2% packing: shockproof packaging in the use of this type of industrial glass rod temperature time, sometimes there will be a temperature measurement error, but it doesn't mean the thermometer is broken. According to our company for many years experience, sort out the causes of errors thermometer mainly has the following eight reasons. ( 1) A zero displacement (always 2) The ball of deformation (temporarily 3) 压力变化( 4) Scale is not accurate, 5) Reading method is not correct, 6) Thermal hysteresis effect ( 7) The special reasons of errors alcohol thermometer ( 8) The special reasons of errors the thermometer when you glass rod thermometer in error, please do not reject, it should be sent to the calibration of the specialized institutions, can the calibration can continue to use, can't calibration needs to be scrapped.
