Before revision: The instrument penetrates haze and mist in daylight or darkness and has a normal range of 30–50 km but can extend up to 70 km.History of the Tellurometer Application Typical distance measurements were between mountain tops The tellurometer design yields high accuracy distance measurements over geodetic distances, but it is also useful for second order survey work, especially in areas where the terrain is rough and/or the temperatures extreme .
