Model TLV25
REF 00T0650 (230V/500-60Hz), REF 00T0780 (115V/60Hz)
MAIN CHARACTERISTICS
The TLV25 system contains a 25 litres Dewar flask. The fluid in the flask must permanently be cooled by a
separate cryostat. The temperature set point is maintained via a microprocessor controlled heating
element. When using the KV40 or KV80 minimum working temperatures of minus 40°C or minus 80°C can
be reached. All presented data is measured by using a TLV25 filled with 25 litres of methanol and a KV40
or KV80 immersion cooler. At the minimum-temperature, the provided heat removal is still enough to
maintain stable temperature control, even when glasswork is placed in the bath. The systems accuracy is
better than the requirements of ASTM D 445 and ISO 3104. The bath is illuminated by a fluorescent light
built in behind the Dewar-flask. The top lid has a turn table construction with 3 holes + 3 lids of 51 Ø
mm. By turning the lid the immersed viscometer can be positioned in front of the window. This window is
heated to keep clear sight at low temperatures. The set point can be set in steps of 0.1°C from -90°C up
to +60°C (-130..140°F). Overall accuracy is better than ±0.03K.
