For continuous carbon dioxide (CO2) monitoring of controlled atmosphere (C/A) food storage rooms, breweries, wineries, food packaging plants, or any area where CO2 is handled.
The Nova 523 Series Carbon Dioxide alarm monitors are designed for the continuous detection of CO2 in ambient air or in air drawn from a confined space or C/A room. A built-in sample pump draws in a sample through a filter and flowmeter and then on to the CO2 detector. This model uses a solid state infrared CO2 detector which continuously detects and displays the CO2 on a front panel digital meter. A 0-1V or 4-20mA linear output signal is available for input to a recorder or similar device.
Model 523P has a built-in pump sensor.
