Compressed Breathing Air (CBA) Tubes and Kits

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.

2 NEW Nextteq® Compressed Breathing Air (CBA) Regulator Kits

Nextteq® offers 2 new and improved Compressed Breathing Air (CBA) Kits

Our new Standard CBA Kit includes the ability to detect common contaminants such as CO, COâ‚‚, Oil Mist and Water Vapor.  Our new Deluxe CBA Kit includes the ability to additionally test for oxygen!  Both kits include the new Nextteq® regulator and flow meter system with upgraded features that improve accurate readings. 


Quality is key and our new Nextteq® CBA Regulator and Flow Meter System is no exception.  The Nextteq® CBA Regulator and Flow Meter System uses a two stage regulator. The first stage reads the pressure from the supply tank. The second stage is adjustable. This adjustable 2nd stage is not found on competitive regulators and allows the user to fine tune the pressure delivered to the flow meter which is part of the regulator assembly.  This allows a more precise and more accurate reading of the target gas.


Testing is made simple!  Once you attach the regulator to an air bottle or you adapt it to an air supply manifold, follow the 3 steps below for all tubes except Oâ‚‚:

  • Break the tube tips and insert the tube with the arrow pointing down
  • Set the delivery pressure and flow rate for the tube being used
  • At the end of the allotted time, remove the tube from the regulator, and read the concentration on the tube.


The Oâ‚‚ tube offered in the Deluxe CBA Kit, uses a syringe kit (with included instructions) to precisely measure the 50cc volume of air needed. 


Key Features:

1) Nextteq® CBA tubes overall require less sampling time (most tubes 2 min or less)

2) Other competitive tubes have a sampling times of 5 min or more!

3) Nextteq® CBA tubes overall have longer shelf life (3 years! Except Oâ‚‚ has 2 years)

4) Nextteq® Deluxe CBA Kit now offers an Oâ‚‚ tube! - proper monitoring of Oâ‚‚ is essential.

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.

Nextteq® CBA tubes measure up to CGA, OSHA, and NFPA guidelines:


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.
