Sentinel environment controller

Does anyone use these? Which one do you use? Are they worth the cash? Any and all info is appreciated on these things.

CPPM-4 user here. I love it. I originally had an XGC-1e by CAP but the unit was too cumbersome plus I didn't need all the extra controllers on it. The Sentinel has a 16' remote CO2 sensor which also detects light so the unit shuts off at night.

How much is that one? I was looking at one for like 500 are they worth that?

I would recommend but do your research and make sure it's what you're looking for. There are a ton of different CO2 monitor/controllers out there.

Its a glorified co2 monitor, bought the CHHC-4 a few weeks after it came out, had it for about a year and sold it. Unless your running somethig on the bigger scale, its really not needed.

I have a sentinel chhc-4. And just purchased the sentinel DEC 4. The Dec for has everything the chhc4 has accept digital co2 control. It even runs a heater unlike most on the market that just have the night only plug in. And the dec4 runs about 2 bills and gets the job done easy peezy.

Now that sounds good.
I'm prolly just gonna get a cheap one for my ac conditioner that's really only why I need it anyways... Plus with winter coming ill be using outside air to cool the lights I got a second inline fan already so I can use one with my filter, and use the other to bring fresh air in from outside. Plus I need a new reflector first, cooltubes suck as far as light spread and penetration
