Review on 🔬 Accurate Formaldehyde Detection: Extech FM200 Formaldehyde Meter by Sammie Rodriguez

If you want accurate analysis results, this probably isn't the best option. If you are looking for areas where there are higher concentrations and making comparisons to narrow down sources, then this is for you. Easy to use and comes with a soft case. The only complaint is that it's the battery drain - buy good rechargeable batteries or plan on changing batteries every 8 hours a day.
