¹ All specifications are at ambient/sea level, 77°F (25°C).
² Please Note: The Nuvair O₂ Quickstick’s dome-shaped end cover is designed to restrict gas flow to the sensor. If the tank valve and analyzer are not properly operated, sensor damage or false readings can occur. Inaccurate gas analysis can lead to serious personal injury or death. Consult the O₂ Quickstick User Manual for proper operation.
³ The O₂ Quickstick warranty period begins on the purchase date when purchased directly from Nuvair.com. If purchased through a third-party reseller (such as a retail store, distributor, Amazon.com, or other e-commerce site), the warranty period starts on the date of manufacture. Why? Because many gas analyzer sensors contain chemical cells similar to battery cells, which have a limited lifespan. Nuvair takes extra care to ship only recently manufactured sensors and analyzers, ensuring the longest possible lifespan when purchased directly from Nuvair.com.
