This vehicle meth testing calculator helps you interpret car meth test results from a New Zealand laboratory. Enter your methamphetamine testing vehicles result in µg/100 cm² to explore modelled vehicle meth contamination and approximate smoke-dose equivalents for your specific vehicle category.

Why Cabin Volume Matters

A Lab Result Means Different Things in a Car vs a House

A methamphetamine surface-residue result is reported in micrograms per 100 square centimetres (µg/100 cm²). On a large property wall, a given reading spreads across a much larger surface area than it does inside a vehicle cabin, where the air volume is a fraction of a room. The same number can represent a very different level of exposure depending on where it was collected.

Vehicle Meth Testing Calculator FAQ

Common questions about the MethShield Auto™ vehicle meth testing calculator.

What is a vehicle meth testing calculator?

A vehicle meth testing calculator is a free online tool that takes a laboratory methamphetamine surface-residue result (in µg/100 cm²) and your vehicle category, then uses modelled cabin volume to produce an approximate smoke-dose equivalent. It helps New Zealand vehicle owners, insurers and fleet managers contextualise a lab result inside the confined space of a car, SUV, van or truck cab.

Is the MethShield Auto calculator free to use?

Yes. The MethShield Auto Vehicle Meth Testing Calculator is completely free. Enter your laboratory methamphetamine result and vehicle category to explore modelled smoke-dose equivalents. No sign-up is required.

What vehicle categories does the calculator support?

The calculator supports five vehicle categories: small car (compact/hatchback), medium car (sedan/small SUV), large car/SUV (large SUV/wagon), van (people mover/cargo van), and truck (truck cab). Each category uses a modelled cabin volume in the calculation.

Does the calculator confirm meth contamination in my vehicle?

No. The calculator produces an approximate modelled estimate only. It does not confirm contamination levels or establish how many times methamphetamine was actually smoked in a vehicle. For confirmation, EnviroCheck provides independent vehicle meth testing nationwide by NZQA-qualified samplers.

Where is the MethShield Auto calculator available in New Zealand?

The calculator is available online nationwide. EnviroCheck provides professional vehicle meth testing across Auckland, Waikato, Bay of Plenty, Northland and throughout New Zealand for vehicle owners, used-car buyers, insurers, fleet managers and transport operators.
