RI-600 carbon dioxide monitor, 0-5000 ppm, 24 VDC operation


SKU: 73-1205-05K Categories: , , , , Tags: ,



RKI’s Model RI-600 measures carbon dioxide in the air. 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. The monitor outputs an analog 4~20mA signal and gas alarm relay contacts open or close when the carbon dioxide concentration rises above preset alarm set point. The Model RI-600 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. Power options are 115 VAC or 24 VDC. The RI-600 has two preset alarms, and comes ready to operate with a simple wall mount bracket and 10 foot power cord.
