Accurate. But springs a little fiddly. Monday, 22 March 2021 | Surrey I am happy with this, it does the job - However, if the back was even slightly concave instead of flat so it sat on the pipe, to make a better contact point, it would respond a bit quicker. However - For the money - A very decent unit. (2 different length springs supplied - Good!) Monday, 22 March 2021 | Surrey These seem to be very good - Accurate - And concur with the others I have and my infra red thermometer. Satisfied!
