this series of thermometers isuniversally suitablefor machine building, refrigeration andair-conditioningindustry.expansion thermometers can be installed inor mounted atnearly all locations. versions with capillaries areused inlocations which are not easily accessible and where longdistanceshave to be bridged.
   case, capillary, stem and process connection aremadefrom stainless steel. various insertion lengths andprocessconnections are available to match the requirements ofeachmeasuring location optimally.
