Our detector only senses ultrasound traveling through open air. **Q: It can power on normally, but after startup, there is no signal at all. Is it a device issue? What can the customer do?** A: Try using the matching ultrasonic transmitter to see if there is a signal. Perform initial tests in a quiet, indoor environment away from background noise. **Q: Is it possible to deteck leaking from heating floor or heating pipe embedded in concrete?** A: Sorry, EM2268 is unable to detect,It's a low pressure system. ## Frequently Bought Together - allsun Ultrasonic Leaking Detector Transmitter Auto Noise Finder 36-44KHz Air Gas Water Leak Diagnosis Tool - Rectorseal 65554 8-Ounce Bottle Better Bubble Leak Locator, Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/85771389-pro-ultrasonic-leaking-detector-transmitter-auto-noise-finder-electronic-stethoscope](https://www.desertcart.sn/products/85771389-pro-ultrasonic-leaking-detector-transmitter-auto-noise-finder-electronic-stethoscope) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-30*
