Description and Specification for Lab Tenders
Cementometer Moisture Meter.
• Fast and easy to use; simply insert the prongs into the material being tested
• Accurate
• Completely Portable
• Full range of water cement ratio's Instantaneous readings
The 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 USB interface to a personal computer
running the Cementometer software.
