* Data from real measurements. By averaging measurement data these values can be vastly improved if maximum sensitivity is required. Typical setting is that the instrument records 3 harmonics from all 4 sensor crystals in about one second.

** Note that an exterior heater/cooler aid is required to reach temperatures below RT and above RT + 60 °C.
