PST offers a range of carbon dioxide infrared sensors that are designed with non-dispersive infrared technology and respond to carbon dioxide across the full range from 500ppm to 100% volume. The Platinum series sensors contain all the necessary optics, electronics and firmware to provide a linearized, temperature-compensated output. Within the Platinum series are low-power options and dual-gas, high resolution methane / carbon dioxide sensor that provides the capability to simultaneously monitor methane and carbon dioxide in a single sensor package, consuming the power of a single infrared sensor. Sensor ranges: Low-range CO2 0-5% volume, including ppm ranges of 500ppm up to 10,000ppm Mid-range CO2 0-10% volume High-range CO2 0-100% volume The sensors are available in Industrial Ex d IIC Certified, Mining M1 Certified, UL Approved, and Non-Certified versions. Low power and EN50271 / SIL1 certified software versions are also available in most combinations.
