The Teledyne IR-700-CO2 is a non-intrusive “Smart” sensor designed to detect and monitor carbon dioxide gas in air using miniature non-dispersive Infrared Optical (NDIR) sensor technology. Available in a low and a high range version, ranges of detection (by volume) are 0-0.3%, 0-1%, 0-3%, 0-5% (low range version) and 0-10%, 0-25%, 0-50%, and 0-100% (high range version). The plug-in, field-replaceable detector provides a selective response to CO2 and features oversized gold-plated connections that help prevent corrosion. The Model 700’s rugged framework includes an electro-polished 316 stainless steel housing with fully encapsulated electronics and dual-layer surge protection.
This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes. A primary feature of the Model IR-700-CO2 is embedded intuitive software that simplifies the operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display. The Model IR700-CO2 is equipped with standard analog 4-20mA, and Modbus™ RS-485 outputs. Additional integration options include a Remote Alarm Module (RAM) & HART. Detcon’s carbon dioxide gas sensor has an infinite shelf life and is supported by a 5-year pro-rated warranty.
