TrolMaster (AS-2) CO2 Alarm Station (audio/visual) plus LED Display Indicator with Cable Set

The AS-2 CO2 Alarm Station is an audible-visual alarm module that features a color-coded LED display indicator and an LCD digital ppm level display. It is designed to be mounted outside of grow-room or grow facilities to monitor the CO2 ppm level. The AS-2 can be linked to either AL-1or AL-2 CO2 sensors channel, or it can be linked to both sensor channels for complete redundancy.

The green LED indicator shows the CO2 level is below 800ppm which means the room is safe to enter. The yellow LED indicator shows CO2 level equal or above 800ppm which means supplemental CO2 is in use. The AS-2 will sound an audible alarm and blinking red LED indicator in the event of the CO2 level going above the user’s preferred level set in the Carbon-X main controller.

*Note: The AS-2 requires the SPH-1 for supplemental power.

Well Worth the Money
Color: Graphite, Style: Keyboard
I bought this keyboard after my last bluetooth one crapped out. I wasn't looking for anything fancy, and it's not. But it is comfortable, and I like the way the keys feel. Honestly, I even like the way it looks. The only downside is that one of the control buttons near the shift button will erase an entire sentence or two if it is accidently touched. That's annoying, but not enough for me to give it a four star. It's fairly quiet. I actually like the way it sounds. I use it every day, sometimes for a couple of hours. The batteries are going strong. I am glad I didn't go for a more expensive option. It doesn everything I want it to. It's compatible with my tablet and connects right away. I don't even have to reconnect it every time. I just start tapping the keys and it is ready to go fairly quickly. Over all, this is a great value for your money. I highly reccommend it.
