Palm D Oxygen Analyzer

Passed my Nitrox certification and brought it with me to the instructor when was doing final exercises. I was very glad to find that it's accurate and work smoothly. The best product in this price range. Highly recommend.

Opened the package yesterday upon arrival and the unit would not power on. No owners manual included, but was able to track down the manufacturer and find the correct manual. Batteries are supposed to included, tested and good for 13,000 hours. Followed the instructions for case disassembly and immediately observed the battery contacts were not close to touching either of the batteries. Pinched them together and reinstalled the batteries and the unit is now working. Also, might be my mistake, but I thought from the product description that this unit was also supposed to come with a blue disfuser attachment and a bag, neither of which were included.

Amazing

Easy to use, cost effective and accurate

Ordered this item assuming that, being new, it would work properly—so I didn’t test it right away. When I finally needed it for a trip and tried to calibrate it to regular air, it showed 25%. Even worse, when checking my nitrox mix, it read 36% instead of 28%—a dangerously inaccurate reading that could be life-threatening for anyone relying on it. I contacted the seller, but since it’s outside the return window, the recommended to contact manufacturer.

Small, accurate, easy to use and a great value

The analyzer itself is great. Product photos are misleading. Does not arrive with the case or blue attachment as pictured. Now I have to go find and buy a small plastic tube that should have been included for Yoke valves.

The analyzer seems to work very well and is quite compact. HOWEVER, in the product information there are two pictures of a case and an attachment, but they weren't sent with the device. This is very deceptive and, while I like the analyzer, I will likely return it because of the deception.
