Best Nitrox Analyzers (including product reviews)

Being able to consistently and reliably check the oxygen level in the mixture of gas that you are going to be breathing while diving is super IMPORTANT. For this reason it is crucial that you use a good oxygen analyzer when checking your gas. Most oxygen analyzers are going to do the job reliably when it comes to checking the percentage of oxygen in your tank, but the best nitrox analyzers are:

  • Analox Oxygen Analyzer
  • Nuvair Quickstick
  • Maxtech Oxygen Analyzer
  • Palm D Oxygen Analyzer

Having a tank filled with Nitrox

When having a tank filled with nitrox at a dive shop, you are always going to want to confirm that the blend of oxygen in the cylinder matches what you either ordered, or what you were told was stored in the dive shop’s nitrox bank.

A lot of dive shops will have oxygen analyzers on hand and allow you to use one in order to confirm the blend of gas that is in your tank. It is best practice to check the oxygen level of the tank while in the dive shop (before you sign the log book and take responsibility for the tank), and also before your dive that specific tank as a redundant check.

Not all dive boats are going to have oxygen analyzers at the ready for you to check your tank prior to a dive, so it can be helpful to own your own oxygen analyzer to do those checks after leaving the dive shop. This can be especially helpful if you have multiple cylinders filled with different blends of gas. Sure, the tank will be marked with it’s contents and maximum operating depth, however mistakes can and do happen so it is always better to be safe than sorry.

This oxygen analyzer is one of the gold standards when it comes to checking the blend of gas in your cylinder. It provides you with the option of checking the tank’s oxygen content directly from the valve, or once your tank is already hooked up to your BCD through an attachment that hooks up directly to your inflator hose. The battery life on the Analox Oxygen Analyzer is great and its portability makes it a no-brainer for anyone certified to dive nitrox.

 Nuvair Quick Stick

Nuvair Quickstick

Nuvair Quickstick
If you make a purchase after clicking this link, we make a small commission at no cost to you. Super Portable

This analyzer is super portable and made out of marine grade aluminum. Most analyzers that you find will be made of plastic, and therefore somewhat fragile in comparison to the Nuvair. The calibration on this model is super straightforward, you simply turn the end of the stick until the machine reads ~21% and then you are ready to analyze your tank.

Both the sensor and battery on this unit are replaceable, so if you find after a time that your readings are inconsistent with other analyzers, you have the option to replace the sensor.

Another benefit to this analyzer is that the housing is water resistant. A lot of analyzers won’t last very long when kept in a super wet area like a dive boat, but that is not a worry that you have to have with the Nuvair Quick Stick.

Maxtech Oxygen Analyzer

Maxtec MaxO2

Portable, reliable oxygen sensor for testing nitrox blends.

If you are looking for an option that is even smaller than the previous two, the Maxtech Oxygen Analyzer is your best bet. This analyzer is super portable, splash resistant and gets the job done.

This analyzer won’t come with the adapter to hook it up directly to your BCD inflator hose, but if that is the style of analyzer that you would like, you can purchase the model that comes with that adapter here.

Palm D Oxygen Analyzer

This nitrox analyzer is going to come in at around the same price as all of the others. It has an easy one click calibration at either air (21%) or pure oxygen (100%). It comes in a secure housing, and the sensor will last around 3 years before needing to be replaced. This unit is super portable, comes in a small size and is super accurate.
