Hembisen WA996 Carbon Monoxide Detectors: Accurate & Easy to Read
Available Options
Meet the Hembisen Carbon Monoxide Detector—your silent guardian against the invisible threat of CO gas leaks. It's not just accurate; it's got a digital display that keeps you in the loop and an alarm loud enough to wake the dead (well, almost, at 85 decibels). Thanks to some fancy imported electrochemical tech, it sniffs out danger without crying wolf over false alarms.
Here’s the lowdown on what makes it tick:
- Plug it in, and you’re good to go—no PhD required for installation.
- It heats up faster than your morning coffee, with a digital countdown to prove it.
- Keeps an eye on CO levels 24/7, like a nosy neighbor but in a good way.
- When things get dicey (we’re talking 150PPM), it screams louder than a toddler denied candy.
- There’s even a self-test button because, let’s face it, we all need reassurance sometimes.
To keep it happy, just make sure that green light stays on and give it a wipe-down now and then. And please, don’t stick it in the kitchen grease trap—it’s a detector, not a deep fryer.

As someone who's worked in logistics, I'm naturally skeptical about safety devices, but this Hembisen unit has met my expectations. I was concerned it might have false alarms or be hard to set up, but reality proved otherwise—it's been reliable since I got it. The packaging was intact when it arrived, which is always a good start. I appreciate that it uses metric units for measurements, fitting my preferences. It's a solid investment for anyone, especially at my age, where safety is a priority. Very user-friendly and does what it claims without fuss. I'd recommend it to others looking for dependable protection.
- Pros: It seemed to me very accurate in detecting gas, with a clear digital screen that shows levels easily. The alarm is loud enough to be heard throughout my home, which is reassuring. Installation was straightforward, just plug it in, and it starts working quickly, heating up fast as promised. I liked that it runs continuously without needing much attention, and the self-test feature gives peace of mind.
- Cons: The loud alarm, while effective, can be a bit jarring if it goes off unexpectedly, but that's a minor issue for safety. It requires occasional cleaning to keep it functioning well, which is a small hassle. I wish it had a way to adjust the volume or sensitivity, but overall, it does its job as intended.
