Description
The RI-600 model measures carbon dioxide in the air. The RI-600 displays the measured carbon dioxide concentration on the LCD. If there are high CO2 emissions, the user is notified by an audible alarm tone and the multi-color LCD digital display. The monitor outputs a 4~20mA analog signal and gas alarm relay contacts open or close when the carbon dioxide concentration rises above the preset alarm setpoint.
The RI-600 model uses NDIR (Nondispersive Infrared Ray Absorption) technology to detect CO2. The infrared beam emitted by the light source penetrates 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 because the infrared energy emitted by the IR source is absorbed by the CO2. This reduced energy is detected by the IR sensor and displayed as a gas concentration. An optical bandpass filter in front of the IR sensor conducts the absorption wavelength of the CO2. The power supply options are 115 VAC or 24 VDC. The RI-600 has two preset alarms and is ready to use with a simple wall mount and a 10-foot power cord.
