🏠 SafetySiren Pro4 Series: The Trusted Leader in Home Radon Detection Since 1993 - USA Version pCi/L Review

I installed this in our basement and couldn't believe how volatile radon emissions were. We had a company that installed a radon reduction system and it was interesting to see the reduction but still variable readings. I have no comment on the accuracy of the readings as I have no other measurements.

I've only had the product for two days. He reported a radon level of 9.4, well above the safe level. It was placed in the work area of the basement, which is most covered in dirt and where the passive radon exhaust pipe is located. One more thing to worry about. Luckily nobody lives/sleeps in the basement. I am in the workroom three times a week for a maximum of 2 hours.

We bought this unit as we recently moved into a house with a radon protection system in the basement. The home failed the initial pre-purchase inspection, so sellers had to take remedial action. I wanted to make sure the system was working and the house was safe. This has been in our basement since we bought it and provides us with both short-term and long-term average values.

Works very well, it was very high in my basement, about 33. A radon company came to me and installed a radon shield. They ran their test and I got the machine running at the same time and the results came back and they were within 10-20% accuracy of each other; Both this block and the actual test. So for me a very accurate instrument. I got it because my son-in-law had generation 3 and I had generation 4; same technology, just a different user interface.

Product arrived as promised; The manufacturer used UPS instead of USPS. Easy to use; You plug it in and it works automatically. No further settings are required. It still takes 48 hours for the first radon measurement, as prescribed (actually, the first measurement took about 60 hours, but it doesn't matter; be patient). I was happy to see that our home radon levels are low (less than 2) even though we have a whole house ventilation system that replaces the air in the house every few days. I…

I have used several radon detectors with a security siren over the years. They were all earlier generations than the ones I recently bought. All the previous ones were great until they died after a few years of use. I believe the sensor sets in these things are fragile and have a limited lifespan. Let's see how this new version holds up over the long term, but I'm not at all happy that I can last a few years considering what you get in that time. Knowing the radon level in near real time is…

The radon detector was delivered on the expected time and in bubble wrap. Winter came and the device was allowed to warm up to room temperature. Next, plug it into an outlet. An error message appeared during the initialization. According to the instructions, the power supply to the facility was turned on. This time the device responded correctly - beeping, flashing CAL, then dotted lines for short term and long term PCI/L readings. According to the instructions, after 48 hours the readings…
