Why I'll only ever buy Teledyne cells ever again

We are keeping a log of all our sensors sales from both Teledyne and Analytical Industries and we will publish the return rates periodically for a true reliability comparison..

brilliant- thats good info! ....like to think it will get published...

we can't tell you the manufacturer at this point because they're all rebadged and we haven't had a chance to talk to the LDS and distributor. last cell change with the teledynes I also had one fail straight out of the bag, so to have that happen this time seems almost "normal" to me. but this time to then have two more (incl the replacement) fail within a week just takes the cake. i personally see this as problem of all cells as there are many similar experiences, regardless of manufacture

Hi Rachel,

When you say re-badged does that mean someone other than the manufacturer is applying a label???

If so how do you identify the manufactures production date??

Could you be a bit more specific with the details and maybe show a picture or two of the sensors?

Hi Matt and Rachel,

Looks like the curse of the dodgy oxygen sensors strikes again. I did three dives today with one Teledyne R17D and one R17D equivalent by the other manufacturer with no problems on either cell. At the start of the fourth dive, the R17D equivalent starts reading low. I keep an eye on it over the course of the dive, but it fails to recover.

Once at home, I measure the mV output in air and 100% O2. In air it was 6.0mV down from 9.7 when new. In 100% O2 it was giving out 37.1mV, down from 46.6 when new. Also, the response to changes in PO2 is now much slower.

Suspecting the cell may be affected by condensation (not that the Teledyne found the condensation a problem) I dried it in a desiccator and remeasured mV output. In air the mV output was 6.7 and in 100% O2 it was 39.2mV. Both readings well short of normal mV range when new, and response time to PO2 change was still slow.

As a final note, the Teledyne R17D is 11 months old and the R17D equivalent is only 5 months old. Any suggestions as to where I can get a Teledyne R22D at a good price and with quick delivery?

Ive had teleydynes fail in exactly the same way (straight out the bag and/or early)

Personally from experience I think all brands of cells are crap and all mnf are as bad as each other.

I agree.....
Some last 2,5 years and some 2 weeks....
Had to replace all the 3 last cells in my Rebreather after 1 week to 3 months.....
I hope this batch is better...

The K1D equivalents are supplied from the manufacturer with the label and packaging of the distributor. there is nothing to say who the manufacturer is. i don't think i can tell what the production date is. i'm at work the cells are at home so can't give serial number right now. i had a look yesterday and there was nothing obvious in the serial number/other markings to indicate date of manufacture. Our source of teledynes in oz has closed business so an order has been sent to Patrick.

What absolute pieces of crap. There is $500 AUS down the drain as a learning experience. I can tell you unreservedly I wont ever be using that brand again.

Matt/Rachel

Unfortunately I can only offer moral support here.

I am hoping that you get this matter resolved to your satisfaction for you both.

We can't have you both being denied the pleasure of getting wet.

I say this after having a top weekend on my Rebreather (In short, 12 hours in and its getting better, and I would be totally pissed if it was me)

Thanks for sharing, let us know how you get on.

Hi Marek,

R22D can be bought from Jeff Giddins at a good price. He will have them to you in the mail pronto. Go to Scuttlebutt Scuba Charters and email him.

He is overseas at the moment but his wife Bev will look after you. Alternatively, give her a call at home. PM me for their landline contact.

We have found cell lag from condensation on long dives (4-5 hours dives). Also, something to consider is corrosion on the molex connectors. That black crap that builds up on the gold molex will reduce the reading from a cell, particularly for high Po2, we have found. By cleaning the gold molex we have found the cell will read much closer to the others.

Hi Dave and Sandy,

Thanks for letting me know about Scuttlebutt Scuba. I have dealt with Jeff before when I sent him a McMaster Carr CMF orifice for his homebuild rebreather. However, I did not know that he resells Teledyne R22Ds. I'll get in contact with his shop later on to sort out the details.

Also, I've tried all the things you mentioned about the molex connectors, but they made no difference. I did the mV readings using a multimeter connected directly to the cell after removing it from the reabreather head. Finally, the Teledyne R17D was in the rebreather at the same time as the R17D equivalent, connected with the same plugs (Molex to mono jack adaptors) but it did not have any issues with condensation or corrosion. Hence I'm pretty sure that the cell is a dud.

Cheers.

Hmm
Just tested the cells i got about 10 days ago approx.
1 has droped from 10.1Mv to 6.1Mv

Looks like i should have not talked to you two the other day,
Rach & Marek your bad luck rubbed off
