These room sensors are available as a CO2 only or as a combination sensor with available CO2/RH/temperature measurements. Available with preset onboard DIP switches that enable user to select analog output signal of 0-5V, 0-10V and 4-20mA for CO2 and RH sensing. Digital outputs BACnet and MODBUS also available on request. Accurate CO2 measurement from 400-10,000ppm CO2 and 2% RH from 10-90%. Dual channel technology and a solid state infrared source ensures long lifetime, excellent accuracy and repeatability with low drift and quick start up. SPECIFICATIONS Enclosure: Injection-molded ABS Cover: Quick snap, injection-molded ABS Mounting: Direct mounting with quick snap faceplate. Fits standard single gang box or mounts directly to wall. Built in level for easy accurate installation. © 2019 All Rights Reserved TH2519 www.tasseronusa.com page 2 of 4 SPECIFICATIONS CONT.
