Inquiry (采购产品): Pressure measurement inside the cylinder Dear Sir/Madam, I need to measure the presure inside the cylinder as a function of frequency. I can not make hole on the cylinder. I just can remove one spark plug and replace it with the measurement device adaptor.Do you have such an equipment? **** Hidden Message ***** Mohammad Hosseini Fouladi 43000 MYS Company: National University of Malaysia E-mail: mfoolady@yahoo.com **** Hidden Message ***** mfoolady@yahoo.com
