Specifications::
James Cementometer™A microwave meter for rapid determination of moisture content
in wet cement and concrete.
The James Cementometer™ represents a
break-through in modern moisture measurement technology. By utilizing
the latest microwave and microprocessor science, the Cementometer™ can
determine the moisture content of freshly mixed cement, concrete, and
mortar. Simply insert the prongs of the probe into the material to be
measured and instantaneously the water cement ratio is shown on the easy
to read display. The Cementometer™ Microwave
moisture meter uses a two prong sensor to measure the
complex dielectric constant of the material in
contact with the prongs. As the dielectric constant of
water
is four to eight times greater than most aggregates andcements,
changes in water content directly effect the sensor
output.
An average of five to ten readings is
normally taken in order to ensure a valid reading. This output
is then converted by the integrated microprocessor and moisture
content is displayed directly.
Two units are available to encompass the
full range of water cement ratio's found in wet concrete.
The Cementometer Type R™ handles
normal water cement ratio's with its two
prong probe. The range of this instrument is approximately
0.35 to 0.65water/cement. Cementometer Type L™
handles low water/cement
ratio's with its
five prong probe. The range of this instrument is approximately
0.25 to 0.5 water cements.
The units come calibrated for standard type I, II, and III
cements.
It can also be programmed with up to ten different mix
design by the
user. For highest accuracy, the user should program the unit for
the material being used. The Cementometer Type R™ has
simple to use calibration process that rapidly creates the user
programs
without the need for external computing devices. Finally, the
Cementometer™ can store over 150 readings.
Storage is complete with the time and date for
future reference. Data can be recalled via RS-232
interface to a personal computer running the James Cementometer™ software.
