The James Cementometer utilizes the latest microwave and microprocessor science to accurately determine the moisture content of freshly mixed cement, concrete, and mortar. This exciting breakthrough in moisture measurement technology uses a two-prong sensor to measure the complex dielectric constant of the material in contact with the prongs. Readings are displayed instantaneously.

The Type R  uses the two prong probe handles normal water cement ratios, with an approximate of range 0.35 to 0.65 water/cement. 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 unit is calibrated for standard type I, II, and III cements. An easy calibration process allows you to create up to ten different mix designs without the need for external computing devices. The Cementometer can also store over 150 readings 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
• Accurate
• Completely Portable
• Full range of water ce ment ratio’s instantaneous readings
