Chuck thermometer in use process how to maintain

Chuck is one of the bimetallic thermometer thermometer, and widely used in food, medicine and other industries of comparative strict hygiene standards, the clamp design can avoid direct contact with the measurement of material, more health, convenient. So in the use of chuck temperature time need how to maintain? 1, chuck thermometer in custody, installation, use and transportation process, should try to avoid collision protection tube, don't make the protection tube bending, deformation. When installation, it is forbidden to twist the instrument shell. 2, temperature instrument often work better in the scale range of 1/2 to 3/4 place. 3, chuck thermometer protecting tube immersed in the measured medium length must be greater than the length of the thermal components, generally greater than 100 mm in length, 0 50 ℃ range into greater than 150 mm in length, so as to ensure the accuracy of measurement. 4, all kinds of chuck thermometer should not be used to measure open containers within the medium temperature, electric contact thermometer should not be at work used in the control circuit of larger vibration occasions. 5, the thermometer in the case of normal use shall be regular inspection. Is every six months. Electric contact thermometer is not allowed to work under strong shock, so as not to affect the reliability of the contact.
