一、Overview
The DZL resistivity tester is the latest drilling fluid resistivity tester developed and produced by our company. It is mainly used to test the resistivity or conductivity of various liquids. It is suitable for the measurement of the resistivity of oilfield drilling fluids and the resistivity of various liquids in other industries. It can also provide reference for the analysis of liquid mineralization and the identification of the purity of water. Compared with the old resistivity measuring instrument, the new instrument has a higher degree of integration. It adopts the American AD analog chip to improve the sampling accuracy and optimize the measurement circuit. It can be compared with imported instruments in terms of accuracy and repeatability, and can completely replace similar imported instruments. Function: 1. Measure the resistivity of liquids; 2. Measure the temperature of the liquid; 3. Automatic conversion of resistivity at standard temperature; 4. The setting of the standard temperature; 5. Temperature error compensation setting; 6. Self-inspection of measuring instrument; 7. Equipped with an external 9V adapter power supply (the socket is on the back of the instrument) and a rechargeable battery.
