About OxyCheq


What began with a home build oxygen analyzer the El Cheapo then later the EL Cheapo II spawned much more after.

OxyCheq analyzers and diving equipment are used by a variety of government agencies, the US Military, industrial, safety, major universities, dive shops, dive boats, technical divers and anything in between. All of the analyzers and diving equipment are built for harsh, demanding environments.


Analyzers were at one time very expensive to purchase and the replacement sensor were equally expensive. OxyCheq changed that when the first batch of Expedition Analyzers were manufactured in 2001. Analyzers that were over $500.00 for the consumer came down to below $300.00 and the replacement sensors that were approximate $125 to $175 depending on the various model of sensor came down to an average of $75.00 to $80.00.

This allowed the increase in use and safety of divers who were mixing gases.

Today there are other manufactures making analyzers and selling sensors. We invite you to look at the cost versus quality and longevity of the analyzers and sensors. We currently provide replacement sensors for consumers and various other markets where the analyzers are over 12 years old.
