ME-31A Visco Bath

Visco Bath for internal temperature applications

JULABO Visco Baths are used for precise temperature applications with
capillary viscometers and density meters within the bath tank. The units offer
high temperature accuracy and optimal temperature distribution throughout
the bath. An integral cooling coil for cooling water is provided for temperature
applications below or near ambient temperatures. The units are equipped
with a holder for thermometers and therefore offer very good options for
temperature calibration procedures and comparisons with accredited
thermometers.
