The FIP conductivity measuring instrument M9.50 is an electronic device used to control the batching or mixing of different liquids. The 4 "widescreen full graphic display can clearly display measured values and other practical information. With a multi-color display and strong backlight, the batch status can also be easily determined from a distance. The guidance software can quickly set each parameter. There are also a few options available to increase accuracy and batch processing time. The feasibility of setting different volumes is associated with specific calibration coefficients, which can optimize system flexibility and accuracy. The batch system can be remotely controlled and monitored through appropriate output kits.
