I rather like the environment devices for Raspberry Pi. Surely they aren't "professional level," but for things like CO2 and other particles and gases, you can generate scrolling graphs. That lets you always know whether things are going up or down at any given moment.
Most of the store-bought devices just beep if too high etc, but having a visible graph certainly tells you if it is measuring anything at all, and if you need to crack open a window or blow out the novel candle you just bought from the dollar store.
