Usage Overview

Used for rapid determination of moisture content in sand or gravel, as well as other fine and coarse aggregates.

The emergence of the fork needle moisture content tester has broken through modern moisture content testing technology. By applying the latest microwave and micro processing technologies, fork needles can be used to test the moisture content of sand, gravel, crushed stone, and all other fine and coarse aggregates. As long as the fork needle is inserted into the material to be tested, the test results will be displayed on the screen immediately.This fork needle microwave moisture content tester is used5Root fork needle sensor to measure the outside4The complex dielectric constant of the material surrounded by the root needle. Due to the dielectric constant of water being the same as that of most materials4to8Therefore, the change in moisture content directly affects the output of the fork needle sensor. Usually we test5to10Next, take the average to ensure the reliability of the obtained results. This output is automatically converted into the moisture content of the material through the internal microprocessor of the instrument and displayed directly on the screen.

The instrument itself has been calibrated for sand and gravel, and users can also program different materials themselves, up to a maximum of10Programming materials. To achieve the highest accuracy, the instrument should be programmed for the material being measured. As long as it is usedWIN95/WINNTThe accompanying software can program different materials.

Finally, the instrument can be stored150A reading. Simultaneously save the testing time and date for future reference. Data can be obtained throughRS232Interface transmission to computer, useWIN95/WINNT.
