    Fails at high temperatures

          Comments about Snap-on Thermometer for Manifolds:

          I purchased five of these snap-on thermometers to monitor the return lines in my hydronic heating loops. The maximum supply temperature in my system is 185F and sometimes the return flow in one zone is around 150F. Apparently this temperature was too high because the glass bulb in one of the thermometers exploded and splashed red dye. The two other thermometers became useless because the red dye (alcohol?) in the glass tubes separated. Caleffi needs to redesign this part so it can withstand the normal operating temperatures seen in baseboard hot water loops.
