FAQ's of APMA-380 NDIR Carbon Monoxide Monitor/CO Analyzer:
Q: How does the APMA-380 Carbon Monoxide Monitor detect CO levels?
A: The APMA-380 uses non-dispersive infrared (NDIR) technology to detect carbon monoxide. This method measures the absorption of infrared light by CO molecules, offering high accuracy and stable, real-time readings.
Q: What is the measuring range and accuracy of the APMA-380 analyzer?
A: The standard measuring range is 0-500 ppm, with an optional extension up to 5,000 ppm. Accuracy is maintained at 2% of reading or 1 ppm, whichever is greater, ensuring reliable monitoring in various settings.
Q: When should the APMA-380 be used for CO monitoring?
A: This analyzer is designed for continuous measurement and analysis of CO concentrations in ambient air or exhaust gases, making it suitable for industrial environments, laboratories, and emissions monitoring.
Q: Where can the APMA-380 be installed for optimal performance?
A: Install the APMA-380 in locations requiring real-time CO monitoring, such as manufacturing plants, research facilities, or exhaust outlets. It operates within 0C to 40C and up to 90% relative humidity (non-condensing).
Q: What is the process for data logging and retrieval with this analyzer?
A: The APMA-380 features built-in data storage that records measurement data continuously. Data can be accessed via the digital outputs (RS-232/RS-485) or through the analog interface, facilitating seamless data management and analysis.
Q: How do the alarm outputs function on the APMA-380?
A: The device includes two independent relay outputs for high and low CO concentration thresholds. These relays can be configured to trigger alarms or control external systems when preset CO levels are detected.
Q: What are the benefits of using this CO analyzer in industrial settings?
A: Benefits include high detection sensitivity (1 ppm), robust stainless steel construction, user calibration capability, real-time monitoring, extensive data logging, and seamless integration into process control and safety systems.
