Five laboratories (33%) have access to a source with an. aperture diameter of 150 mm or larger. The minimum calibration temperature offered is -80 Â°C and the maximum is 3000 Â°C, with the most common. temperature range (i.e. broadly achievable by the majority of the respondents) being -30 Â°C to 1000 Â°C.
