Question: What is the range of PPM that this meter can detect, or how high can it detect?
Document: It seems to read a bit high on the CO2 scale. It reads about 400 ppm when I know it is 385 ppm, but otherwise is OK.
works perfect love it . if you need to monitor your c02 this is the monitor to use. recommend it to every one
shipping was super fast so they get an extra star. other than that this thing maxes out at 3000ppm. just breathing on it it goes from 400 to saying (Hi ppm &#60;3000)without any other readout ... so don't expect to use it for anything important. this co2 unit kind of feels cheap and junky, I'm returning mine ... you get what you pay for
Well worth the price. Works as well or better than some more expensive brands. Accurate and dependable. Glad I purchased this model.
The monitor works well and is durable. It would have gotten 5 stars if it were battery powered instead of a plug in only.
The down side is that it takes a bit, like 12 second to update, but that is not a big deal. It helps me know how much co2 is in my room. However, I think I will save more co2 if I get a automated co2 dispenser.Nonetheless, with this device, and a regular timer, I make a 20lb co2 tank last 14 days.
Perfect for any size garden large or small very accurate and I like how it takes a reading every 30 seconds so you know what the readings are at all time
Now even for someone like me who is a floral enthusiast (if I may say so myself) and has seen an impressive array of gardening electronics come and go, I have to say this device does it all. I grow a number of flowers ranging from orchids to sunflowers to daffodils in my backyard greenhouse.
Maybe it's a good thing if you don't have to worry about batteries running out and plants dying. You decide. Will post an additional review after some time.
It's slightly larger than my iPhone 4, powers up in about 20 seconds, at which the first co2 reading can be seen with temperature and humidity levels.It works fantastically for my indoor plants. The black panel has red, yellow, and green LEDs that indicate CO2 levels of too low, relatively low, and good, respectively.Since it's rather cold outside these days around 40 deg Fahrenheit, with the air conditioning turned on and windows shut tight, the plants are maintained at 925ppm CO2.
Answer: yes
