Rapid, Freeze-Thaw Cabinet—
The Rapid Freeze-Thaw Cabinet is used to measure the resistance of
concrete to deterioration caused by repeated cycles of freezing and
thawing in water. The system is designed to test up to eighteen 3"
x 4" x 16" (76 x 102 x 406cm) concrete specimens simultaneously,
with one being a control. Key features of system include:
Fully automatic operation frees operator to perform other lab
duties.
Allows users to establish field control using correlations between
concrete strength and durability
Permits the evaluation of variables in concrete properties and
conditioning.
Useful in the evaluation of the durability of aggregates, as well
as the properties of admixtures.Up to eight freeze-thaw cycles are possible within a 24-hour
period. But the exact number of cycles is dependent upon the time
required for the temperature at the center of the control prism to
from 40 to 0°F (4.4 to -17.8°C) and then back to 40°F (4.4°C). The
temperature at the center of the control specimen is cycled by
means of a 3/4 HP (0.6KW) refrigeration unit and electric
resistance heaters with fully automatic controls. An electric
temperature recorder with 24-hour, 7-day week chart is incorporated
into the unit to accurately maintain a record of the control
specimen temperature throughout the testing period.
For corrosion resistance and long service life, the system features
a stainless steel, 84" x 34" x 11" (213 x 86 x 30cm) cabinet
construction with 3" (76mm) insulation on all sides. The internal
test compartment measures 6" x 26" x 74" (15 x 66 x 188cm). A
30-amp circuit is required for operation. Meets ASTM C666,
procedure A; and AASHTO T161, procedure A.

Rapid, Freeze-Thaw Cabinet— H-3185B
Rapid, Freeze-Thaw Cabinet, 220V 50/60Hz— H-3185B.4F
The H-3185B uses on/off control of heating and cooling devices to
cycle between two temperatures. It can be set to cycle continuously
between two temperatures for a finite number of cycles and then
stop. When set to run for a finite number of cycles, ramp rate
between temperature extremes can be adjusted, as well as soak
duration at each extreme.

Rapid, Freeze-Thaw Cabinet— H-3185SD
Rapid, Freeze-Thaw Cabinet, 220V 50/60Hz— H-3185SD.4F
The H-3185SD goes beyond the basic capabilities of the B model
above and provides the following capabilities:
User-created test capabilities are possible, to change freeze time,
temperature minimum, temperature maximum and the number of cycles
to run.
Real-time, on-screen testing with graphing, allowing different data
views to be chosen.
Test data can be reviewed after a test is completed, which includes
tabulation and graph views.
Touch-screen interface for easy navigation.
Export test data to a PC using Humboldt IR Download. This includes
report
creation for internal or customer usage.
Connect to the Freeze-Thaw Cabinet remotely for control and/or
observation.
