Short summary
The paper presents a portable sensor system that measures the bacterial concentration in metalworking fluids (MWFs) exploiting impedance microbiology. Good agreement has been found between the system response and that of the reference plate count technique (PCT). The proposed system allows automated bacterial concentration measurements with shorter response times than the PCT (4 to 24 h vs. 24 to 72 h) and is suitable for in-the-field MWF monitoring.
