Best Oxygen Analyzer for Oxygen Machine (2026 update)

Oxygen analyzers measure oxygen levels produced by oxygen generators, oxygen concentrators, oxygen systems, and oxygen machines. Typically, these devices combine measurements of oxygen purity concentration (O2), flow (F), and pressure (P). Oxygen analyzers consist of an ultrasonic sensor that detects both oxygen and nitrogen, ranging in price from $300 to $5,000.
Best Ozone Detector (2026 update)

Ozone detectors measure the concentration of ozone in the air. These analyzers can measure ozone in the air to provide a parts per million (ppm) concentration. As an unstable gas, ozone has a unique nature that must be considered during detection. Ozone gas decays to form oxygen as a function of temperature, humidity, time, and air agitation. Therefore, it can be tricky to measure ozone in a consistent fashion. In this guide, we present essential information about ozone detectors and tips to ensure accurate measurements.Â
CO2 Monitor for Indoor Air Quality (2026 update)

Air quality monitoring has become an important topic since the COVID-19 pandemic. Carbon dioxide (CO2) monitoring has been at the center of the conversation. Used to track air quality levels, CO2 meters are employed in classrooms, gyms, workplaces, and offices. They are a fantastic proxy to pathogen transmission risk and are even required for indoor use in some cases. A typical carbon dioxide monitor has adjustable alarm settings to allow users to be in compliance with various CO2 exposure limits.Â

How to Test a Carbon Monoxide Detector (updated for 2026)

To ensure accurate functionality, it is important not to use your car's exhaust gas to test your carbon monoxide (CO) detector. Instead, it is recommended to use carbon monoxide gas that is available in a bottle or can. It is also important to periodically test carbon monoxide meters and detectors to ensure their sensitivity to carbon monoxide gas. This article presents a simple method of testing CO detectors and meters without requiring any special tools.

Low Level Carbon Monoxide Detector (2026 update)

Carbon monoxide (CO) is a deadly gas that must be taken seriously. It is known as the "silent killer" because it is colorless, odorless, and tasteless. This is the exact reason why so many states and cities have mandated carbon monoxide detectors in homes. Along with their importance for home safety, CO detectors are crucial when traveling, RV driving, and boating.
Best Oxygen Analyzer for Scuba and Oxygen Purity (updated for 2026)

An oxygen analyzer is a critical tool used by divers to confirm the oxygen levels within their gas cylinders. It is essential that the oxygen analyzer is reliable as air inhalation during diving is the biggest safety concern. Oxygen analyzers used for diving are also referred to as a scuba analyzers, O2 analyzers, or simply as oxygen analyzers. They are easy to use and display the oxygen concentration in %vol of the gas cylinder.
Best Headspace Analyzer (updated for 2026)

A headspace analyzer is an instrument that detects gas content in food packaging. Food packaging is often filled with nitrogen and carbon dioxide to reduce oxygen, preventing food from spoiling and extending shelf life. A headspace analyzer provides food packers with quantitative gas concentrations so that products meet the expected quality control thresholds.
CO2 Meter on CNBC (Interview with Dr.Koz)

Seema Mody, a global markets reporter for CNBC, interviewed Dr. Koz in December 2020. She was reporting on the Pfizer vaccine rollout, specifically on the ultra-cold temperatures required for storing the COVID-19 vaccine. Developed by U.S. pharmaceutical giant Pfizer and Germany-based BioNTech, vaccine shipment and storage has driven a buying frenzy for freezers and dry ice.
CO2 Monitor for Indoors and Schools (updated for 2026)

Yes, kids are safe in classrooms as long as carbon dioxide levels stay below 1000 ppm. Due to the pandemic, CO2 has become an important gas in our lives as it is linked directly to airborne pathogen concentration. The good news is that schools are taking indoor air quality much more seriously because of COVID-19. In order to keep our kids safe, school districts are actively improving ventilation and carbon dioxide monitoring.
