Process Control and Instrumentation Ordinary mercury in glass thermometer is used for measuring temperature upto 120°C. However, for measuring higher temperature upto __________ °C, thermometer is made by filling nitrogen under pressure above the mercury, which stops the evaporation of mercury and reduces the chance of broken thread of mercury. 550 250 350 700 550 250 350 700 ANSWER DOWNLOAD EXAMIANS APP
