Am I Getting the Most Accurate Ignition Interlock Device? Calibration Methods

November 21, 2017

If you have an Ignition Interlock, regular calibration appointments are necessary to ensure your device is still accurate when you perform your tests. Ignition Interlock vendors have calibration methods, using specialized calibrating units, that are designed specifically for breath alcohol testers.

The two main calibration method types are dry gas and wet bath.

At Smart Start, we offer our clients NHTSA-approved dry gas standards to ensure you have the most accurate calibration possible and the most reliable Ignition Interlock Device.  You can have confidence in our calibration processes knowing each dry gas cylinder has a NIST-traceable Certificate of Analysis, assuring consistency and precision.

So, Why Are Calibration Instruments Important to Me?

These types of calibrations make sure you have a reliable and accurate Ignition Interlock Device.

Dry Gas

The dry gas method uses an alcohol gas mixture in a sealed, pressurized tank or cylinder. This method requires very little maintenance, is more stable and is less sensitive to temperature than wet bath standards.  The alcohol concentration in the cylinder does not change due to usage, so every calibration will be the same until the cylinder is empty.

Save time and money during your IID program. Discover quality and affordable Interlock Devices at Smart Start. Get Started!

Wet Bath

The wet bath method uses a water alcohol liquid mixture that is heated in a specially designed device. The equipment for wet bath calibrations must be properly maintained and the temperature accurately controlled to ensure a clean system that provides an accurate alcohol concentration at each calibration. Unlike the dry gas method, the water alcohol mixture must be regularly changed since the alcohol concentration degrades from continuous use.

Dry gas requires very little maintenance and is not susceptible to a change in concentration due to each usage. Wet bath equipment must be frequently cleaned and degrades with each breath test.

Between the two methods, dry gas is superior to wet bath in application and maintenance. Therefore, dry gas is the better method in Ignition Interlock Device calibration and maintenance.

Smart Start has the best in Ignition Interlock Devices, calibration instruments, software and customer service. If you are looking for a seamless and easy Ignition Interlock program, Smart Start is the right provider. With an SSI-20/20™ or SSI-20/30™, your required period with your device won’t be stressful, and you can get back to your everyday routine.
