Abstract

The invention concerns an arrangement for temperature measurement and/or temperature profile measurement of frozen ground containing one or more measurement sensors 2 connected to a housing 1. The arrangement also includes the installation tube 3 into which the housing part 1 together with its sensors 2 will be inserted. During temperature measurement the measurement sensors 2 can be placed in contact with the installation tube 3 by using a moveable device 5 connected to housing part 1. The disposable installation tube 3 is made of a cheap material, whereas the measurement sensors are of high quality and precise, like Pt-100 measurement sensors. <IMAGE>
