Measuring exhaled CO2 levels ensures air is conditioned only when needed. The CT1R is a flush mount design sensor with NDIR sensing element and features that include an optional LCD and setpoint relay, menu selectable auto-calibration and provision to offset the reading +/-250ppm. Now available with a dual-channel CO2 (DT1R) element for more accurate sensing in continuously occupied spaces and greenhouses. APPLICATIONS ▪ Ventillation control in response to occupancy ▪ Facilitates compliance with ASHRAE 62.1 standard for air quality ▪ Offices, conference rooms, and public assembly areas ▪ Hospitals, continuous occupation (dual channel version) The industry’s best looking CO2 sensor meets demanding architectural standards. ▪ Fits in most standard j-box or low voltage brackets. ▪ No exposed screws; unobtrusive tamper resistant design Easy to install and maintain ▪ Integrated display and push-button menus for field selectable scale, calibration, and operational modes ▪ Dual 4-20mA and 0-5V/0-10V output (switch selectable) ▪ Integrated high-reliability solid-state set-point relay is ideal for direct control applications; easy to set up thanks to LCD High reliability reduces call backs ▪ Non-dispersive infrared sensing element (NDIR) ▪ 15+ year life expectancy on CO2 sensing element ▪ Industry leading 7-year limited warranty on electronics (NDIR module 2 years) High accuracy for improved system performance ▪ Selectable auto-calibration mode returns sensor to baseline values ▪ ±30ppm, ±3% of reading NEW! Dual Channel CO2 Option ▪ Senva’s dual channel CO2 sensor allows for more accurate CO2 sensing in continuously occupied spaces and greenhouses. ▪ Dual channel technology employs a calibrated reference chamber within the sensing element to minimize drift.
