Review: Pretty good tool - Works pretty good found an air leak in one of the airbags on my semi! Review: Found a leak soap or UV dye wouldn’t. It’s made for HVAC, not tires! - Fantastic item. Just shut off fluorescent lights first, they put off a ton of noise. Found a leak in less than 60 seconds. People who have issues with this don’t know how to use it properly or patiently.

This saved my behind and made a happy customer with the first use. ## Features - Detects pressure and vacuum leaks for all gases - Hear the leak using the included headphones - Works even in noisy environments - Laser pointer makes it easier to pinpoint the leak - Applications include pressure/vacuum leaks, electrical arcing, malfunctioning steam traps, and more - Only technology to detect pressurized nitrogen leaks - Runs on two D-cell alkaline batteries - Rugged carrying case included - Made in the United States, US Technician Support via Email and Phone ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000TRJA8M | | Alarm | Audible | | Best Sellers Rank | #58,826 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #67 in Leak Detection Tools | | Brand | Inficon | | Built-In Media | Whisper, Headphones, Rubber extension probe, 2 D-size alkaline batteries, case | | Color | Grey, White | | Customer Reviews | 4.0 out of 5 stars 216 Reviews | | Enclosure Material | HAWA | | Global Trade Identification Number | 00689466037111 | | Item Dimensions D x W x H | 5"D x 12"W x 16"H | | Item Type Name | Ultrasonic leak detector | | Item Weight | 3 pounds | | Manufacturer | Inficon | | Mfr Part Number | 711-202-G1 | | Model Number | 711-202-G1 | | Number of Items | 1 | | Operating Humidity | 95 percent | | Power Source | Battery Powered | | Product Dimensions | 5"D x 12"W x 16"H | | Product Style | Laser | | Sensor Type | Ultrasonic | | Style | Laser | | UPC | 810044830583 689466037111 | | Unit Count | 1 Count | ## Product Details - **Alarm:** Audible - **Brand:** Inficon - **Color:** Grey, White - **Global Trade Identification Number:** 00689466037111 - **Item Weight:** 3 pounds - **Operating Humidity:** 95 percent - **Power Source:** Battery Powered - **Product Dimensions:** 5"D x 12"W x 16"H - **Sensor Type:** Ultrasonic - **Style:** Laser ## Images ![Whisper, Ultrasonic Leak Detector, 711-202-G1 - Image 1](https://m.media-amazon.com/images/I/51-FR-Apg0L.jpg) ## Available Options This product comes in different **Pattern** options. ## Questions & Answers **Q: how small of a leak will it measure?** A: Very small **Q: would I need the transmitter device to leak check air conditioning coils etc?** A: This is a simple tool to hear the whistling of high pressure air going through a small opening. The high frequency pitch is picked up by the microphone. You won't need anything else to operate this. I prefer to use my own headphones instead of the ones in the kit, but that is a personal preference. It also has a sound bar so you can see it, too. You don't need to listen, although I find it helpful. **Q: if I pressurize my underground pool skimmer line with air, would this be practical for locating a leak?** A: I don't believe it will help in this application. To detect the leak, you must be able to see the line and place the unit relatively close to the hose. So for your application, you would need to expose your lines. If your pool skimmer lines are visible, it is easier to inject a dye, such as a UV dye, and shine a UV lamp to find it. If your lines are not visible then you would need to dig up the line to look for the leak. When I had an underground leak, I hired a person to find it for me. It was worth the money for the one time repair. **Q: Is good for bearing friction detection?** A: Hello and thank you for your question. Yes, with the optional metal contact probe (711-703-G1) Whisper can detect malfunctions in certain mechanical components, bearings included! The contact probe is included with the version that comes with the accessory kit (711-203-G1). Simply screw the metal contact probe to the tip of Whisper and touch it to the suspected mechanical component. For the best experience, use a pair of headphones to utilize Whisper's heterodyne feature. Properly functioning machinery sounds smooth and clear, whereas malfunctioning machinery may produce grinding, scratching, or other irregular noises. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pretty good tool *by Z***. on May 31, 2026* Works pretty good found an air leak in one of the airbags on my semi! ### ⭐⭐⭐⭐⭐ Found a leak soap or UV dye wouldn’t. It’s made for HVAC, not tires! *by W***M on April 29, 2025* Fantastic item. Just shut off fluorescent lights first, they put off a ton of noise. Found a leak in less than 60 seconds. People who have issues with this don’t know how to use it properly or patiently. It’s really not complicated. I had a leak I couldn’t find with UV dye or soap. This saved my behind and made a happy customer with the first use. ### ⭐⭐⭐ Not able to detect tiny leak rates *by S***S on March 19, 2026* It does work as advertised but only if the leak rate is large enough to generate where it can detect it. The issue is there is no specifications for that such a grams/year which we in HVAC/R refer to. It does serve a purpose if used within its capability. Good for detecting motor bearing noise, ultrasonic devices, and could detect nitrogen pressurized equipment. Water on the tubing and cores does aid in locating the leak. Using headset is a must. . To give an example of a tiny leak rate where it did not detect it, see attached video. ## Frequently Bought Together - INFICON Whisper, Ultrasonic Leak Detector, 711-202-G1 - Inficon 711-703-G1 Contact Probe for Whisper Ultrasonic Leak Detector - INFICON 711-600-G1 Transmitter for Whisper Ultrasonic Leak Detector --- ## 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.pt/products/1701259-whisper-ultrasonic-leak-detector-711-202-g1](https://www.desertcart.pt/products/1701259-whisper-ultrasonic-leak-detector-711-202-g1) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-28*
