The AEGTEST HOUND-1011S is designed for continuous monitoring, with readings and history you can review over time. Place it in a basement or another area you want to monitor. Its color screen shows radon levels in pCi/L or Bq/m³, while audible and visual alarms provide another way to notice readings. The portable unit weighs 0.28 kg and can run on its built-in battery or stay connected with the included Type-C charging cable. That flexibility makes it practical to move between monitoring locations or leave in one place. ## Where it shines The HOUND-1011S measures radon from 0.09 to 1,000 pCi/L and lets you switch between pCi/L and Bq/m³. Its semiconductor sensor provides the first reading within 12 hours, then updates hourly. This gradual start and regular refresh support a more useful picture than relying on a single moment: you can check how levels develop in the space you are monitoring. The display includes views for the past 12, 24, 48, 72, and 96 hours, and the device supports longer-term monitoring across periods extending to 504 days. On-device graphs help make changes easier to follow. For a basement check, for example, you can position the detector in the area and use its recorded readings to track conditions over time. The built-in stand supports placement, and the audible and visual alarms offer clear alerts. ## Key takeaways This is a home-focused detector for people who want readable radon measurements and a monitoring history in one portable unit. Switching measurement units is useful when you prefer either pCi/L or Bq/m³, while the color TFT screen puts readings and graphs directly on the device. The stated measurement range is 0.09 to 1,000 pCi/L. For extended placement, the detector supports continuous monitoring while connected to power. Its built-in battery lasts up to 45 days in sleep mode, giving you another way to use it when it is not connected. The package includes the HOUND-1011S, a charging cable, a lanyard, and a manual. Buyers commonly praise the straightforward operation, readable display, and usefulness for monitoring radon in different parts of a home. Their feedback also highlights battery life and ease of navigation, these are user impressions, while the monitoring features and operating details above describe the device itself. ## How to take care of it For readings, keep humidity below 90%, high humidity can affect measurement. A dehumidifier or air conditioner can help manage the room environment. Strong light, including direct sunlight, can also affect the sensor, so place the detector away from direct exposure. If strong light reaches it, the manufacturer advises moving it to a dark spot before testing again. After restarting the device or using Retest, the measurement screen resets while historical data is preserved. Allow time for a new reading to appear. These simple placement and operating practices help the detector collect readings in the conditions where you want to monitor radon. ## When it makes sense Choose the HOUND-1011S when you want more than an occasional number: it combines portable placement, hourly updates, selectable measurement units, alarms, and on-device graphs for following radon levels over time. It suits you if you are monitoring a basement or checking more than one area and value having the readings visible on the detector itself. For longer monitoring at home, its included stand and option to remain connected make it easy to keep the unit where you need a continuing view of radon conditions. ## Images ![AEGTEST HOUND-1011S Portable Radon Detector with Color Display and Alarms — 1](https://www.ofertitastop.com/i/5uz3qb3m28jLkWf3LHna_YKchw4DIjtbtP9iTZdk6gB-8u1Mkf9rkYlsPh-1NX33Da0NeQl21TNHOR0WteWDWL_87qFYuJHYAEi5Jk6z98hIxc_tXFwoJjPtTA.jpg) ![AEGTEST HOUND-1011S Portable Radon Detector with Color Display and Alarms — 2](https://www.ofertitastop.com/i/A_SdUobLn2W_WQ4x0XaVkptmBLi_LHILibII_5CMsaubamd8NJQRoryo1DtApug-HyOA_peJk6OFLz9w0WOPFs7iRuU-ALrDAAXKHAfxT9R-2IAZSCgzsfI2MQ.jpg) ![AEGTEST HOUND-1011S Portable Radon Detector with Color Display and Alarms — 3](https://www.ofertitastop.com/i/TGVf7WqzS1EtKhztWK0Clf_UA410DNUyoU6ej7hdOsQ43MSAcUtvlMyyW2pJKDNHhcoDCzGxCVt3AJajYCn5v06SDd17FftGXR6w7k5I9108Q6Qmy1Pufp0dPA.jpg) ![AEGTEST HOUND-1011S Portable Radon Detector with Color Display and Alarms — 4](https://www.ofertitastop.com/i/Dak2ZLbX2sGP_iaIy6N-vLD6HyY1b9Y3kqxuJNKQ9FWpmnV3XZkrZ2QtRTS9YO9YQobx-vz3MFzudTgu1zmL1sJpbGT8yigG7o053j95wIjoGamfW6xCVJqutw.jpg) ![AEGTEST HOUND-1011S Portable Radon Detector with Color Display and Alarms — 5](https://www.ofertitastop.com/i/LJz7KqFFt5lGfC24YXm5yo0HrJ2gaBe9OvJY7guAgNEYlO7FYuNatQxVDv0HdWukV-9gU4oIdI4yBEGQN2StZceqFD9VKjj6cjM6BnlZbMmBIuD43NlR10HgdA.jpg)
