Series FN2/FN3

These thermometers are suitable for use outdoors and in aggressive environments. Gas expansion thermometers with clip-on bulb offer some benefits to the user: no change in pipeline cross-section; the line thus remains piggable and retrofitting can be carried out without interfering with the process simple mounting If the exact orientation of the indication is not known before mounting, we recommend using the positionable version. With this version the case may be re-positioned once by ± 180° with respect to the pipeline.
