The Dry Gas Tanks come from the manufacturer with a stated certification date which is listed on the side of the tank. Intoximeters guarantees a minimum of twenty months for 108 liter, 55 liter, and 30 liter gas tanks.  The Maritime sets are certified for five (5) years.

After the expiration date, the manufacturer can no longer guarantee that the gas value will remain stable.

A copy of the MSDS is attached to each new dry gas tank when it is shipped to you.  The form is also available online or it can be requested from Customer Service.

Dry gas standards should not be used when the gas temperature is below the ‘dew point’ temperature for that gas.  The ‘dew point’ temperature is a function of the concentration of alcohol in the gas and the pressure of the gas in the tank. Contact Intoximeters technical support for specifics about the gas that you are using.

As a general rule when using your dry gas standard, both the gas tank and the instrument should be at room temperature.

Pressurized dry gas standards are considered HAZMAT and you will, at a minimum, have to empty the tank before disposal.  Different states have different laws on the disposal of such canisters.  You can try contacting your local waste or sanitation company to determine the requirements in your state.

Alternatively, you can contact your state’s Solid Waste Management Office and ask for your local guidelines. You may follow the link below to the EPA Government website to get your state contact information.

You may also follow this link Tank Disposal for more instructions.

Intoximeters offers a Dry Gas Tank Draining Tool to assist customers in emptying their expired tanks.

Dry gas standards require HAZMAT packaging and handling and therefore require that a person certified to ship this type of material ships it.

Unless you or your organization is properly certified, you should not ship the tanks. 

When you receive a new tank, you should always place the regulator on it and mark the pressure reading on the regulator (A new tank should have at least 1000 pounds of pressure). 

If there are no obvious leaks, you should leave the regulator on the tank and check the pressure reading one to two hours later.  If the gauge has not moved, you can leave the regulator on the tank.  If it has moved, then either the regulator or the tank is leaking.  

Contact Intoximeters Customer Service to get help in identifying the culprit.

Yes, the same regulator can be used on the 108 liter, 55 liter, and 30 liter tanks.
