I'm looking to source a Non-Linear Junction Detector for our upcoming projects. We're particularly interested in units that offer high sensitivity and reliable performance in identifying electronic components. Additionally, I'd appreciate more details regarding your available models, pricing, lead times, and any bulk purchase discounts. Understanding the technical specs and capabilities of your detectors would also be helpful in making our decision. Thank you!
