@@jayminpatel1948 No. There are little nubs for standoffs at the corners that barely keeps them elevated off the table. I have three of them and I just leave them sticking off the edge of a table or shelf so that area isn’t blocked at all. It has to give a more accurate measurement being exposed to open air than a solid surface 1 mm below the openings.
Our measurements are Bg/m³. Your measurement of 4 being bad is equal to our 200 Bg/m³ being the same level of alarm. So, you being 0.5/4 is only 1/8th the danger level. Be happy with your results. Where I live, we can see 100/200 Bg/m³. (Which would be 2 on your scale). That is 50% of the critical level for concern. 😬
