RKI Instruments 73-1205-20K Standalone Indoor Carbon Dioxide Monitor

RKI Instruments 73-1205-20K standalone indoor carbon dioxide monitor helps keep you and your employees safe by monitoring CO2 levels. The RI-600 displays the measured carbon dioxide concentration on the LCD. If a high level of CO2 is present, the user is notified by an audible alarm tone and the multicolored LCD digital display. Applies Non-Dispersive Infrared Ray Absorption (NDIR) technology to detect CO2. The infrared beam emitted from the light source passes through the gas cell and reaches the IR sensor. When CO2 enters the gas cell, the amount of infrared energy received by the IR sensor decreases since the infrared energy emitted from the IR source is absorbed by the CO2. This decreased energy is detected by the IR sensor and is displayed as a gas concentration. An optical band pass filter in front of the IR sensor passes the CO2’s absorption wave length. This particular model measures CO2 at 0-2.00% volume and has 24 VDC as the power option.
