The 3-97 NORM meter, the classic NORM measuring tool with hard resin carrying case and license exempt check source.
The Ludlum 3-97 NORM meter is excellent for measuring NORM in all kinds of processing facilities. This istrument is highly sensitive to Alpha, Beta and Gamma radiations. It has been modified for the easiest possible operator usage. Color coding and labelling to identify proper settings for each detector. The analog meter dial allows for a more natural response.
