The sensor shelf life is apparently limited, but I have not been able to find what the limit is. This is another difference between the high priced testers and the less expensive ones. The high priced ones have some kind of fixed sensor technology. But again, I don't know the specifics as I am just learning some of this myself. If you find anything out - please share!
No. I tested offline up to 5LPM. But I have read conflicting things on this tester and hesitate running 10LPM directly into it. I still plan to do it, but need it for other testing in the short term. Some of the readings I have seen say there is risk of damaging it beyond 5LPM. But again, I have read conflicting things.
From what I wtched you dont recommend to measure 12lpm of O2. I have a concentrator from Clearwater Tech and I want to know if Im getting enough purity from it, as I can´t seem to get high enough concentration of O3. I am thinking that maybe the O2 concentrator is failing. What other device can I get to measure 10-12-14 lpm O2 concentrator
Hi Roberto. I dont know if it can test beyond 5LPM. I intend to try it soon. But I am reasonably confident that if I am getting high 80s/low 90s at 5LPM, that I will still get a higher % at higher flows. O2 testers are expensive, here is the one my seller used, as he needs professional grade. www.vitalitymedical.com/invacare-check-o2-plus-oxygen-analyzer-device-irc450.html?feed_special=bing&**LP%20-%20Shop%20-%20%27Respiratory%20Therapy%27%20-%20(%24250%2B)%20-%20General&INVIRC450_ea%20%7C%20Invacare%20Check%20O2%20Plus%20Oxygen%20Analyzer%20-%20IRC450%20%7C%20%24587.89

Thank you! I dont see a model number. Here is the name and US Amazon link: High Flow O2 Liter Meter (2-15 LPM) to Measure Oxygen by Responsive Respiratory. www.amazon.com/gp/product/B07VJ1VCYR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
No, not in most situations. I have watched it sample ambient air at the exact same reading percent with and without it. I think the bulb comes into play when you are sampling from a closed pipe of static air or something like that and need to pull air in.
I don't remember. I did it multiple times and was not focused on the time to full O2. I was more focused on the performance of the tester. Per some prior discussions 94% might be slightly high. Apparently when the bulb is attached it can slightly elevate the O2 results. I also was not overly focused on the manual calibration as I just wanted to know it would test into the high 80s/low 90s.
I cant say what you have locally, especially since inventory goes up and down. Likely you will have to order. This guy provided my concentrator, and was easy to work with and fast: bradshawoxygen.com/. And I worked with this vendor, but he never had inventory at the time, but appeared reliable in our conversations: o2crs.com/ (and he is recommended by Ben Greenfield on his EWOT blog).
Type "cy-12c oxygen sensor" in any search engine. Many companies sell this with only slight variations in the collection tubing. Thanks for checking out this video. If you do buy one, please come back and tell us how it worked for you!
Sorry darn, didnt see this question. If you have not found one already, search on, "0-8 LPM Pen Style Liter Meter" or "Standard Flow Liter Meter" , or some variation of that....

@@danishindian2107 Thank you. You are helpful. I havent had a chance to buy the tester. Do you feel significant air flow change while changing flow rate setting from 1 LPM to 5 LPM ?
@@weyonchin Sorry, I dont understand your question. When you move from 1L to 5L per minute flow, you do feel it. I dont know what you might consider significant or not...? Don't you have a flow meter? Is that the concern, no flow meter so you are trying to manually feel?
It was 21% to 94%. The reason it started at 43 was to shorten the video. It took several minutes. I am checking on the reason for that as I don't know if that was because of the sample time of the tester, or ramp time on the concentrator. Thanks for stopping by!
I confirmed. The ramp time to maximum O2 output can be up to 10 minutes (depending on concentrator size). This is not the tester, but the concentrator.
@@danishindian2107 you need to remove the bubble part in order to let the air flow through. The CY12 starts to show increased levels of O2 even if you start applying some pressure to it, while the bubble is connected, or the outlet is blocked ..
@@CaraokeSahil Thank you Sahil, I appreciate it. And I am not sure I understand? Are you saying removing the bubble will speed up the move to maximum oxygen? According to my supplier the concentrator takes a certain amount of minutes to get to maximum oxygen no matter what, is this not correct?
@@danishindian2107 I'm also using the instrument to test a concentrator that I've designed. What we observed is that if you apply air pressure (even normal air) on the inlet and block the outlet of the instrument, the oxygen level starts to show a considerable increase. Now in you video, I noticed that you have the bubble attached. This is blocking air flow and is creating some pressure on the sensor. Oxygen percentage in this case will falsely show higher than what it actually is. You need to let the air through, in order to see the actual %. This is my observation. Hope you've understood my point.
If you are talking about the Invacare combination flow and O2 tester that is far better at every level than the CY12C. The CY12C is a budget tester that only tests O2 level. The Invacare tests both flow and O2 level - but at a much higher price point. If you can budget the Invacare, that is the device to get.
@@ВалентинКАРАПЕТРОВ-ш5ф I only have experience with those two devices, and limited experience at that. I needed to test my concentrator, so I found the budget solution and tested it multiple times. I am confident in the budget solution, but I am not an expert on multiple O2 testing devices.
I see they went up about 50% on Amazon, but I still see them under $100 or right at $100 on varied popular Asian sites. I have only bought from banggood once, so I cannot speak to thier quality and reliablity, but I see it there for $86: usa.banggood.com/CY-12C-Gas-Analyzer-Professional-Portable-O2-Oxygen-Concentration-Content-Tester-Meter-High-Accuracy-Oxygen-Detector-Monitor-p-1807893.html?cur_warehouse=CN
I also see it on www.alibaba.com/ for around $105. I have also purchased from them only once some time ago, so cant speak to them overall. Thank you for stopping by!
94% on my tester? Yes it was.....what makes you think otherwise? It was 95.8% when I purchased it as measured on a pro testing unit. But per my video there is a small bit of variance in there as my tester can be "adjusted" to match what room level O2 is. I set mine to 20% as I am at 400 feet above sea level (20 or 21 is what I use so it might be 1% high....). When I bought my unit it had been fully rebuilt - everything. I am still new to this, is there a reason why you think 94% is not correct? Please let me know, thanks.
Hey, thanks for the info. I'll leave the bulb off since you said that can mess with it.
What will be sensor shelf life?
Can we change sensor when it is defective?
And which sensor we have to choose?
Thank you!

The price has gone up a bit since I posed the video.
Thank you
Is it actually necessary to have the squeezy bulb attached on the other end when the air is constantly flowing through the sensor?
No, not in most situations. I have watched it sample ambient air at the exact same reading percent with and without it. I think the bulb comes into play when you are sampling from a closed pipe of static air or something like that and need to pull air in.
How long it take to get 94% from the first start?
I don't remember. I did it multiple times and was not focused on the time to full O2. I was more focused on the performance of the tester. Per some prior discussions 94% might be slightly high. Apparently when the bulb is attached it can slightly elevate the O2 results. I also was not overly focused on the manual calibration as I just wanted to know it would test into the high 80s/low 90s.
