I'm looking for a quote for a portable eddy current detector. Please include details for the following components: surface probe, absolute probe, differential probe, conductivity probe along with the block, and calibration blocks made of aluminum and steel. Additionally, I need information on both threaded and unthreaded bolt hole probes. Your prompt response with pricing and availability would be greatly appreciated. Thank you!
