Q20 Series Portable Analyzer - O2 and/or CO2

Test O2 and/or CO2 levels in packages, processes, and more!

The Q20 series is the handheld version of Quantek Instrument’s latest product line. It offers the advantage of being incredibly lightweight and portable. With a battery life of 12+ hours, the Q20 series is used in hundreds of applications including container spot checks, food packages, bio enclosures/incubators, and many more!

The Q20 series of analyzers features a color display, menu driven setup and calibration, a built-in programable sample pump, and on-board data collection. Everything you need to start sampling is included. The analyzer ships in a TSA-approved protective carry case, and is backed by our 2-year warranty.

The latest fast response O2 and CO2 sensors

The latest fast response O2 and CO2 sensors, which allows results to be obtained in 15-25 seconds for rapid spot checks. The oxygen sensor is rated for 5 years of life, which is far better than the competition. Other analyzers utilize cheap oxygen sensors which may last 18-24 months. When required, replacement is easy and inexpensive.

The sensor is unaffected by high levels of background gases such as nitrogen.

The CO2 sensor design has a low internal volume and requires only a low sample flow of about 5 to 1000 cc/min. Our market leading CO2 sensor uses the latest in dual-wavelength NDIR measurement principles, reducing drift and allowing for a single point calibration. While the sample introduced should be clean and dry (non-condensing),a PTFE filter can be attached to the tip of the sample probe to protect from moisture and particulates.

Q21 uses a solid-state infrared sensor which has no moving parts, a compact optical cell, and microprocessor-based calibration factors using a 6th order polynomial equation to linearize the full range measurement up to 100%. Infrared CO2 measurements are inherently non-linear, especially over a high range of concentrations. The math algorithm used in the Q21 yields more accurate measurements over a much wider range of concentrations than other methods.
