Precise thermometric testing and recording of a given sample - or determining ambient temperature and humidity - is often an integral part of accurate materials testing. Measure the water temperature by submerging the thermometer two-thirds below the surface of the water. Record the temperature in the beaker in Data Table 2. They are available at any pet store for <$10 or on-line. A thermometer is an instrument that measures temperature. Hold some ice in hand, as soon as it starts melting, the temperature of the liquid water in the palm is just above 0°C Let it stay in palm for a bit, until there's no temperature difference felt with other fingers; this would be around 37°C The non-contact feature of this thermometer makes it one of the best tools for measuring extremely low or high surface temperatures. The range of this thermometer is from 35 o C to 42 o C. For other purposes, we use the laboratory thermometers. View solution > Two thermometers are constructed in the . (b) Thermometer (i) for measuring the temperature of both. ii. Out of all thermometers, these thermometers can be the most complex to use due to issues like spot-size and emissivity. 2.1 All reference temperature measuring devices used by a laboratory to calibrate PRT's thermocouples, liquid-in-glass thermometers and radiation thermometers should be calibrated, and should be traceable to ITS-90.
