The chart below shows various materials resistance to ozone oxidation. This chart should be used as a reference only. Some materials will be affected by ozone differently in wet, or dry conditions. Also, materials will react differently with higher or lower ozone concentrations . If you have questions about the materials used in your application, contact us , we would be glad to help.
A = Excellent - no effect from ozone in normal operation
B = Good - some oxidati...
General Calibration Information
All Gas Sensors will require periodic calibration to ensure your gas measurements are accurate and correct. Different gasses, and sensor manufactrers will have differeing requirements and methods for calibration. This page will serve to provide general calibration information and links to specific calibration procedures from the sensor manufacturers we represent.
Should you have any questions about sensor calibration, or would like us to help you with your ...
Volatile Organic Compound (VOC):
What is VOC:
Volatile Organic Compounds, more commonly known as VOC's consist of a wide variety of organic compounds that are vapor at room temperature. Many different gasses may make up VOC's, and some of those gasses may also be associated with other families of gasses. A complete list of VOC's can be found at the bottom of this page.
Health Risks of VOC's:
VOC's can cause respiratory, allergic, or immune effects...
Aeroqual Portable Monitors Calibrations FAQ
This technical information on this page is relevant for the Handheld Series-200, 300, 500, and Fixed Mount Series-900, 930, 940. For information on the SM-70 and SM-50 scroll to the bottom of this page.
1. What do I calibrate - the monitor or the sensor head?
Aeroqual’s unique system of interchangeable sensor heads means they can be calibrated independently of the monitor. If you are sending a sensor head to us for f...
EcoSensors devices have a variety of different sensors and calibration options and prodedures. These will vary by product and sensor used in that product. See the list below for your specific sensor and relevant calibration information. First, follow our short list of FAQ's to familirize yourself with general calibration inforamtion.

This document refers to the C-21 and earlier EcoSensors VOC Instruments
Replacement sensors for the C-21 are available from Gas Sensing for $50. Please contact us for ordering information.
The Eco Sensors C-21 responds to most reducing VOCs, but not with the same degree of response for each VOC. The response is essentially logarithmic. For the first half of the scale (to about the 2nd yellow bar), the response is approximately linear. After that, it gets sharply logarithmic (much more c...
