Tri Meter?

[Sinisterzane]

Hi all,

I am thinking of putting one of these on one of the totes on an undercurrent system and pointing a picture messaging camera at it and have it send pictures to an e-mail address...

I am wondering if anyone has used one and how accurate it is? I need something thats relatively accurate especially regarding the water temp in case the chiller or pump were to break down....

I am also thinking of pointing another camera directly at this

As of another post I realise how inacurate these cheaper co2 ppm sensors can be but I am looking to make sure I know when the bottles run out and also to check the co2 controller hasnt gone nutty and decided to empty into the room all at once...

anyone any ideas? Maybe the Bluelab guardian is better as the EC and temp is calibrated straight out the box?

No help but thank you

I didnt know you could just buy a co2 detector without it also being a controller.Here in the states we use tri-meters to catch ghosts lol

Hannah & Nutradip make trimeters (about same price $175 USD), more familiar w/Hannah. Also cSense CO2, Temp & %RH Monitor w. Relay looks nice but a bit pricey, Titan Controls Atlas 1 - CO2 Monitor /Controller and C.A.P. has a CO2 PPM Monitor.

My pick for a trimeter is the bluelab guardian:

A lot of growers including myself like bluelab combo meter as well - measures ph ppm temp tds ec cf, not waterproof but portable.

That's pretty inexpensive for a trimeter (the one that you show Sinister) and I wouldn't trust an off brand like that especially w/trimeters... unless others like it. I'd try and keep these away from digital ballasts as it could have interference. Even fluoros can be a PITA sometimes.

those things suck i used to have one get a bluelab like stonefree said. if i were you anytime in the future i would never get a meter that you calibrate with a screwdriver those things are fuckin ghetto. always get one that calibrates using a button and bluelab is supposed to be the best.
