Features & Applications:
The James Cementometer represents a breakthrough 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 and cements, 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.
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 0.65
water/cement.
The unit comes 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
WIN95/WINNT.
Features:
- Fast and easy to use; simply insert the
prongs into the material being tested
