Rated 5 out of 5

Great tool all EANx divers should own

I love this device! It works amazingly well and every time I've checked it against more expensive or commercial analyzers, it's been spot on - both when using the direct connection hose as well as through the tiny air hole against a cylinder valve. I definitely recommend getting the plug to extend the life of the oxygen sensor as those are obviously the "high cost of ownership" part. Very useful when travelling and/or on boats to verify your EANx mix.

Peace of mind

It... analyses. This analyzer gave me peace of mind when traveling. Remember, it is important to calibrate it based on temperature and humidity. The included chart makes that easy.

Easy and accurate

Easy to use. Accurate when compared to other analyzers. Calibration knob is very sensitive. I like that there is s humidity chart.

reliable, easy to use

If you dive a lot, and like to check your own mix (like PADI recommends), this is a pretty simple gadget. You can use it with or without the BC attachment. I prefer without it, actually. After calibrating for ambient humidity (pretty easy with a current local weather lookup on your phone), the readings are easy to take. The only thing easier would be to have a built-in humidity sensor, or a way to enter the relative humidity and have the internal computer calibrate.

Nice upgrade

Nice upgrade to my last analyzer. I would recommend ordering the cap at the same time. Be very careful when you put the sensor inside as the wire gets in the way.

Analox O2EII Pro Nitrox Analyzer

Analox O2EII Pro Nitrox Analyzer

The O2EII Pro is a small, lightweight and rugged oxygen (O2) analyzer. Designed to check the quality of your scuba diving gas mix, the O2EII Pro can be used directly at the tank or through a BCD adaptor while in harness (BDC adaptor is not included - see SKU: AQUNAC).

This highly accurate analyzer comes with a three year graded sensor warranty and an expected sensor life of four to five years in air. (see SKU: AQUNAOAS and SKU: AQUNASC)

Features:

• Fitted with a hose barb allowing the O2EII Pro to be used while checking air quality at the tank or while connected to the first stage regulator.
• Provided with a temperature compensation chart, allowing the O2EII Pro to be calibrated correctly depending upon temperature and humidity.
• Quick and simple to use, the O2EII Pro is a tried and tested oxygen analyzer.

Analox O2EII Pro Nitrox Analyzer

An updated version of the O2EII, the O2EII Pro is the ideal portable nitrox analyzer, which can easily be taken on all of your diving adventures. The addition of the hose barb now allows the unit to be used while checking air quality at the tank or while the user is connected to their first stage regulator (via their BCD's low-pressure inflator). Note: To check via BCD low pressure inflator you need to purchase SKU: AQUNAC. To correctly plan for nitrox diving, all nitrox divers need to know the gas mix in their tanks. Analox Sensor Technology offers a range of nitrox analyzers (also known as oxygen analyzers) as well as spares and accessories to assist any scuba divers looking to start nitrox diving. Quick and easy to use, the O2EII Pro is splash proof, drop proof and is easy to transport when going on your annual dive holiday. The O2EII Pro is robust and ergonomically designed to ensure a comfortable grip. The O2EII Pro is small, portable and battery operated, meaning it can be taken anywhere.

As a diver, confidence in your mix means you can relax and enjoy your dive. Now you can check your tanks on the boat, making sure the tank you filled is the tank they hook up! The new Analox O2EII Pro is designed to be a major step forward in diver safety. Building on the success of the O2EII, the O2EII Pro retains the same qualities but with many additional features. There are many O2 analyzers on the market, many of which will give you an accurate read on your Nitrox... what sets the O2EII Pro apart is its absolute superior construction and design: drop it, kick it, bang it around, fish it out of the water, it will still give you the most accurate O2 read, be the most comfortable in your hand, and last far longer than any of its competitors. Analox value is in their quality.

The O2EII Pro oxygen analyzer is designed to measure oxygen levels in the range 0.1 to 100% O2 for tank oxygen level verification. The O2EII Pro is ergonomically designed and equipped with several features to ensure ease of use and reliability. The instrument has been designed to be held in the left hand to enable ease of use when checking your tank. It is fitted with a large digital display and operates from an internal temperature compensated electrochemical oxygen sensor. Power is provided by a 9V battery which will last for approximately 1 year before replacement is necessary. The O2EII Pro will automatically switch off after 10 minutes to ensure battery life is not compromised if the instrument is accidentally turned on.

The O2EII Pro is water and drop resistant. Designed specifically for the diving industry whether you may be a sport Nitrox, commercial or military diver - where hostile environmental conditions are the norm not the exception. The O2EII Pro is supplied ready to use, all you need to do is push in the EII adapter. The analyzer has an on button that also acts as a hold button to freeze the reading on the digital display. The O2EII has a typical accuracy +/- 1% of reading +/- 0.2% of O2, an operating temperature of 23 Degree F to 122 Degree F (-5 Degree C to +50 Degree C), a sensor response of 15 seconds to 90% of final reading, a resolution of 0.1% O2 and provides a 4-digit LCD display reading. Included with the analyzer are a sensor saver cap and owner's manual.
