High quality mechanical heat meter with
plastic housing 


The main features of the plastic mechanical heat meter are the
plastic body of the mechanical heat meters. We make the mechanical heat meters
with plastics body for main two reasons: one is that the body of the plastics
are very strong, but at the same time, it can save a lot of costs for the
users. The second is that our mechanical heat meters with plastics housing meet
the NSF requirements and it is very good quality plastic housing, it can pass
the NSF testing and take the place of brass body in some North American
countries.


 The mechanical heat meter with plastic housing is
mainly used for measuring the heat exchange system releasing and absorbing the heat with the carrier of water, besides, for heat supply or cooling heat
system.
