I had the device on for a while and it could read the so2 levels in my car. After passing the areas and the smell went away in my car the air levels were good. I’d say this device is greatSeems accurate. Just can’t change the function from Celsius to farenheit. It’s pretty light. Very good, just pricy :(I am measuring the air quality where I go for my kids because we live in Hawaii where there is so2. I have yet to test it where there is so2 in the air. But so far it can detect good air. Also the humidity at my dads house is way less and at my sisters house it’s a lot more, which is expected so I would say it is accurate. ### ⭐⭐ 2.0 out of 5 stars Leaves a lot to be desired *by J***. on Reviewed in the United States on June 17, 2018* The chinglish instructions are VERY poor. The meter does not give believable readings but it may need calibration. Instructions discuss calibration but there is no stated requirement to calibrate. And the calibration instructions are hard to understand. At any rate, it should have been calibrated at the factory. ### ⭐⭐⭐ 3.0 out of 5 stars Safe readings as pertaining to my home air *by W***W on Reviewed in the United States on July 19, 2018* It’s ok don’t know Celsius or what the frormyldahide readings should be or the safe reading --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/50623108-multi-testers-indoor-air-quality-detector-accurate-testing-formaldehyde-hcho](https://www.desertcart.pl/products/50623108-multi-testers-indoor-air-quality-detector-accurate-testing-formaldehyde-hcho) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-21*
