AI cells in the Meg

could also try this sensor,I hear are very good.

maxtec ~ premier o2 solutions :: max23

all the best.

looking at the specifications it doesnt look suitable for rebreather use..

30 seconds response time full scale (teledyne and AI are <6 second)

it lists an operating pressure range and does not list a hydrophobic membrane... by the specs its a replacement for a teledyne medical sensor not a diving sensor..

This one cell listed above was reading just shy of 60 mV for 4 dives and then dropped to 38.x during the next calibration. I switched the cell around to make sure it wasn't a wire problem, and the cell read the same mV no matter which spot it was in.

Same here exactly with the R22 I'm talking about: dropped from 57mV down to 37mV overnight. I moved it around too for the same reason.

Because of this cell behavior, I now calibrate at the beginning of every day (usually one to two dives in a day).

Same here for the same reason even though cal on the HH is very stable.
Great, we have the same protocole. Seems like we could buddy up if I ever travel you way

. I'd take that drysuit I got from you last year so you'll recognise me on the pier

Philippe,

Do you have any plans to come and dive? Keep an eye on the SCRUBS Forum for up and coming trips. Next month, we have some out of towners diving in the Keys.

Best wishes,

Eric

your right Joe on full scale, teledyne and AI do not show this on there spec
sheet, however my guess is they are the same. the reason for this is that
they show <6 second response time @ t90= 90% not at 100% that you think.
as for the hydrophobic membrane, I put a call in to maxtec about this
as soon as I hear something I will let you know.

all the best.

Just heard back from Jim Chapman with Maxtec, their sensors are compatible
with teledyne and AI sensors, And do come complete with hydrophobic
membrane. So it looks like there is another player in the market.

all the best.

we have the MAX 12 cell listed as a dive cell in our cell checker info but looking at it i do not think it is.
looking at there specs they are not suitable for diving in fact they do not mention rebreather or are equivalent to rebreather cells, so i would guess they do not have temperature compensation required for rebreathers, they may have a membrane but this dose not mean they are good for rebreathers,
I'll try and send an email to get a sample or 2, and if any one has there cells that are not needed any more please send them to me so i can do formal testing.
any help will be appreciated from people that have cells they want to donate in this range.
kind regards john routley
