Equipped with headphones and a laser pointer, it excels in noisy environments and ensures precise leak location. Powered by two D-cell alkaline batteries, it comes with a rugged carrying case and a 2-year replacement warranty. Made in the USA with dedicated technician support, it’s the trusted tool for HVAC and industrial professionals. ## Description Whisper uses ultrasonic technology to listen for the sound of a gas moving through a leak site, making it a super versatile tool for leak checking any gas in pressurized or vacuum systems. Point Whisper at ceiling pipes to gross leak check from the floor. You can even use Whisper in noisy environments! 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. 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. Review: Gran herramienta para HVAC - Por mucho, mejor que los detectores que tiene que “oler” el refrigerante. Es súper rápido hacer verificaciones con este equipo y es muy sensible. Excelente herramienta de diagnóstico para los trabajamos en HVAC. ## 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 - Two-year replacement warranty - Made in the United States, US Technician Support via Email and Phone ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000TRJA8M | | Alarm | Audible | | Brand | Inficon | | Built-In Media | Whisper, Headphones, Rubber extension probe, 2 D-size alkaline batteries, case | | Customer Reviews | 4.0 out of 5 stars 207 Reviews | | Global Trade Identification Number | 00689466037111 | | Item Weight | 1.36 kg | | Item weight | 1.36 kg | | Manufacturer | Inficon | | Mfr Part Number | 711-202-G1 | | Model Number | 711-202-G1 | | Number of Items | 1 | | Power Source | Battery Powered | | Power source | Battery Powered | | Product Style | Laser | | Style | Laser | | UPC | 810044830583 689466037111 | | Unit Count | 1 Count | ## Product Details - **Alarm:** Audible - **Brand:** Inficon - **Item weight:** 3 Pounds - **Power source:** Battery Powered - **Style:** Laser ## Images ![INFICON Whisper, Ultrasonic Leak Detector, 711-202-G1 - Image 1](https://m.media-amazon.com/images/I/51-FR-Apg0L.jpg) ## 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 ### ⭐⭐⭐⭐⭐ Found a leak soap or UV dye wouldn’t.

The supplied open air headphones are not really up to the task. I bought a $10 pair of Koss UR10 headphones and what a difference being able to hear an eye blink and electrical arcing from a light switch. Using the headphones is the way to go instead of the built in alert. I just got the kit a short while ago and have not put it through its paces but will be forthcoming and think it will have a place to aid diagnosis. The one truck A/C I pressurized with nitrogen did not have a leak. Looking forward to see if it can pick up condensor/evaporator leaks. I got to use this today for compressed air leaks on a truck and it found them all in no time flat including the Hi-Lo range valve body on top of the RoadRanger. Using the extension probe it could pick up a leak 8" away from a tank automatic drain valve. I put my finger over the port of the valve and could not tell it was leaking but it was. This ultrasonic leak detector is awesome and a game changer. Will update when used for A/C leaks. ## 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.tn/products/608426566-inficon-whisper-ultrasonic-leak-detector-711-202-g1](https://www.desertcart.tn/products/608426566-inficon-whisper-ultrasonic-leak-detector-711-202-g1) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-31*
