Abstract: The microcomputer-controlled ceramic mud moisture testing instrument utilizes the principle of capacitance sensor and directly exports the signal of high frequency into a microcomputer.By means of numerical model calculation, you can measure the moisture content of the material to be tested. The instrument doesn't need to fix Standard curve in EPROM. Users only import the apparent density of dry material and the moisture of two different wet materials into the computer. The computer can finish definite standard auto­ matically. In order to eliminate temperature effect to accuracy, a temperature compensator is used in the computor.
