Temperature Measurement Lab

A thermometer is a clever device for measuring the average.

Temperature measurement lab.

Temperature is the measurement of the average kinetic energy of the particles in a substance or scientifically speaking a system. In the first few pages of that spec it states that all measurements are valid at 68 f 2 or 20 c 1. The objectives of this lab are to familiarize you with some of the various types of temperature sensors in current use to calibrate them and hence to recognize the relationship between data quality and instrument calibration and to evaluate the impact of ventilation on temperature measurement. In our low temperature measurement laboratory we perform a variety of electrical transport experiments.

Temperature standards international temperature scale of 1990. Its 90 calibration points between 272 5 c and 1085 c triple point of hydrogen 259 3467 c triple point of water 0 01 c melting point of gallium 29 7646 c boiling point of water at 1 atm 100 c not a std. Astm hg thermometer regular hg or alcohol thermometer keep the same one for the entire temp lab davis weather station temperature probe thermocouple bead thermistor or platinum resistance thermometer dewar wind tunnel stopwatch ice electric kettle water paper towels 2. Temperature measuring instruments are used in this lab representing all four of the above categories.

Liquid in glass thermometer thermocouple thermistor infrared pyrometer and optical pyrometer. It ranges from 10 c to 110 c. Temperature measurements from several of these instruments are compared. If measurements are not recorded at this temperature range then one must calculate and compensate for thermo expansion.

Temperature measurement laboratory 1. This is the key reason why qa labs are maintained at 68 f. In this lab you will also calibrate the davis temperature sensor for your weather station. Laboratory thermometers are designed for lab purposes such as checking boiling point freezing point or temperature of other substances.
