The NEW Trerice
Hydro-Therm is the ideal
instrument for both hot and
chilled water hydronic
applications. The blue,
organic “spirit” fill is easily
read without the the
environmental concerns
of mercury. The sturdy Valox
case is available in rigid
straight or rigid 90˚angle
configurations. The 2" stem
makes this the perfect
instrument for smaller pipeline
and other such applications.
The 1/2 NPT brass thermowell
is included.
