Electrical thermometers are widely used for measuring the surface temperature which consist of a flat temperature probe for having lead wires and a metal housing as it only exhibits a very slight difference in temperature between the actual surface temperature and the measured value and these electrical contact thermometer are known for thermometers as these measure the surface temperatures which have round and flat temperatures probe s which are either attached directly or by way of an intermediate carrier to the object to be measured. This electrical thermometer of the invention which makes possible more exact temperature measurements than previously where by the difference between the actual surface temperatures as the measured value is very small.The types of electrical contact thermometer are variable electric contact thermometers are very much high in performance and yield higher output and also these variable electrical thermometers are based on latest technology these electric contact thermometers are very much in demand today. The other type is called as fixed electrical contact thermometers which have steam lines resistance which are used for flue gases and the air is subjected to lead a pull out a test and a thermal response time test. Apart from these electrical contact thermometer the other type is called as infrared thermometers which are known as non contact thermometers because of their ability used to gauge the temperature with the help of these infrared rays.
Fixed electrical contact thermometers are offered in top quality and the steam line resistance thermometers make use of flue gases and airs are subjected to lead pull out test and thermal response time test is obtained. The features of electrical contact bimetallic thermometers are that it displays the temperature directly on the spot and has high reliability along with long life expectancy. This thermometer can automatically break power and alarm.
