* Data from real measurements. By averaging measurement data, these values can be vastly improved if maximum sensitivity is required. The typical setting for the instrument is to record three harmonics from all four sensors in about one second.
** Note that an exterior heater/cooler aid is required to reach temperatures below RT and above RT + 60°C.
