Tech note from EcoSensors
The Eco Sensors UV-100 calibration can be fairly accurately monitored using the Eco Sensors OG-3 Calibration Checker if the calibration of the OG-3 is checked and adjusted for accuracy at the user's altitude. The OG-3 is calibrated in Eco Sensors' laboratory at 2,100 meters. At lower altitudes the OG-3 will generate ozone at a slightly higher concentration than the standard .1 ppm due to the higher molecular density of air at lower altitudes. This difference in OG-3 outpu...

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...
