Nextteq's Compressed Breathing Air (CBA) Regulator Kits
We continually strive to offer the very best solutions for your testing challenges!
01
Test 5 substances listed in Compressed Gas Association's (CGA) Grade D standard for breathing air:
CO, COâ‚‚, Oil Mist, Water Vapor and Oâ‚‚.
02
All Nextteq® detector tubes are length of stain and allow for quick and easy reading of target chemicals!
03
The new and improved Nextteq CBA Regulator has an adjustable 2nd stage which allows the user to fine tune the pressure delivered to the flow meter of the regulator, allowing a more precise and accurate reading of the target gas.
04
No power required - every component is intrinsically safe.

Did you know?
Some common breathing air contaminants are carbon monoxide, carbon dioxide, oil mist, and water vapor, as well as oxygen deficiency.
Oxygen
Oxygen, in general, is not toxic at standard pressures and is necessary for sustaining life. In fact, it is a vital component for respiration and the proper functioning of our cells. We breathe in oxygen to support various biological processes in our bodies. However, exposure to excessively high or low levels of oxygen can have adverse effects on the body. Low oxygen levels can result in Impaired cognitive function and coordination, respiratory and cardiovascular issues, organ damage (e.g., heart, lungs, liver and kidneys), and hypoxemia (i.e., low oxygen levels in the bloodstream). Conversely, prolonged exposure to elevated levels of oxygen can lead to oxidative stress, lung damage, and other adverse effects. Proper monitoring of oxygen levels is essential for the safety of workers.
Carbon Monoxide
Of the common potential contaminants, CO is the most deadly. It is colorless and odorless with no warning properties. CO combines with blood hemoglobin more readily than oxygen causing oxygen starvation in body tissues. Exposure causes headaches, heart palpitations, and loss of equilibrium, confusion, unconsciousness, and death.
Carbon Dioxide
CO2 is also toxic but can be tolerated in much higher concentrations than CO. Effects are somewhat similar to CO, but the increased breathing rate accompanying COâ‚‚ poisoning increases the intake of all coexisting contaminants. Exposure causes headaches, dizziness, sweating, shortness of breath, increased heartbeat and blood pressure, coma, asphyxiation, and convulsions.
Oil Mist
Oil mist and particulate matter are forms of condensed hydrocarbons. The larger particles are readily removed by the upper respiratory tract, but smaller particles can be retained and cause problems. Oil mist in the lungs can cause lipoid pneumonia, and emphysema.
Water Vapor
Water Vapor in a breathing air system causes different problems. It can promote system corrosion and cause regulator failures due to icing in cold weather. It can destroy the catalyst in a filtration system that removes CO by converting it to CO2.

Gas to be measured | Nextteq® Tube No. | Measuring Range(s) (ppm) | Sampling time (min) | Qty of tubes/box | CGA Grade D | OSHA | NFPA |
---|---|---|---|---|---|---|---|
Carbon Dioxide (COâ‚‚) | NX801 | 100-3000 | 2 | 10 | ≤ 1000 ppm | ≤ 1000 ppm | ≤ 1000 ppm |
Carbon Monoxide (CO) | NX802 | 5-100 2.5-5 | 2 4 | 10 | ≤ 10 ppm | ≤ 10 ppm | ≤ 5 ppm |
Oil Mist | NX803 | 0.3-5 mg/m³ | 25 | 10 | ≤ 5 mg/m³ | ≤ 5 mg/m³ | ≤ 2 mg/m³ |
Oxygen (Oâ‚‚) (Deluxe Kit only) | NX804 | 2-24% | 1 | 10 | 19.5-23.5% | 19.5-23.5% | 19.5-23.5% |
Water Vapor (Hâ‚‚O) | NX805 | 20-160 mg/m³ | 1 | 10 | * see note ↓ | ≤ 67 ppm or ≤ 49 mg/m³ | ≤ 24 ppm or ≤ 19 mg/m³ |
Water Vapor (Hâ‚‚O) (Optional) | NX805H | 100-1000 | 20 sec | 10 |
* Note:
Water Vapor CGA Guidelines for Grade D Air: The allowable concentration is based upon a dewpoint of ≤ -65℉ or ≤ -54℃ and is dependent on ambient air temperature.
For example: at a dew point temp of -65℉ and a standard ambient temp of 25℃ or 77℉, the absolute humidity is 28.2 mg/m3. As the ambient temperature increases the absolute humidity concentration decreases.
To calculate the humidity concentration using your ambient temp, use this link: Dew Point Calculator
