Temperature-compensated density is typically only necessary when a density meter does not contain a Peltier element to keep the sample at a specific temperature (such as 20 °C or 40 °C) – most portable density meters on the market today lack a Peltier element. Because of this, measurements can only be performed at ambient temperature.
Many standards and norms, however, require that measurements are performed at a specific temperature for consistent and comparable results – and allow for temperature-compensated density measurements in case a Peltier element is not available. To fulfill this requirement, portable density meters such as the METTLER TOLEDO Density2Go offer the option to perform such temperature-compensated measurements. This means the user can measure at ambient temperature, and the obtained result can be compensated to a specific temperature, whether it is 20 °C, 40 °C, or something else.
This application note shows you how to measure the temperature-compensated density of your sample with the Density2Go portable density meter, including measurement parameters and results – as well as a comparison between results obtained with a Density Excellence benchtop meter and the Density2Go portable meter.
