Eco Sensors, Inc. has developed the Model UV-100, a versatile UV absorption analyzer designed specifically for ozone measurements. This compact and efficient instrument employs a mercury lamp filtered at 254 nm, a common method used in commercial instruments for ozone detection. In this blog post, we will provide a comprehensive guide on how to operate the Model UV-100 Ozone Analyzer, including its features, operation, data output, calibration, and various application examples.
Features of the Model UV-100 Ozone Analyzer
The Model UV-100 Ozone Analyzer offers a wide range of features that make it suitable for a variety of applications. Here are some of its key features:
- Three Measurement Ranges: The UV-100 can measure ozone concentrations in three ranges: 0-1 ppm, 0-10 ppm, and 0-999 ppm, providing flexibility for different measurement scenarios.
- Multiple Output Options: It provides various output options, including an LCD digital display, 0-2.5 VDC, 4-20 mA analog signals, and a time- and date-stamped digital data stream for external readout and data logging via a serial port and USB connection.
- Internal Data Logging: The UV-100 includes an internal data logger capable of storing approximately 36 hours of data. This feature ensures that data can be recorded even when the unit is not connected to an external device.
Operation of the Model UV-100 Ozone Analyzer
Here is a step-by-step guide for operating the Model UV-100 Ozone Analyzer:
- Power Supply: Plug the AC adapter into an AC power source and connect it to the instrument’s power jack. Turn on the UV-100 using the power switch on the rear panel. Wait for at least 30 minutes for the instrument to warm up.
- Sample Inlet Connection: Connect the sample feed tubing to the instrument’s 1/4″ input compression fitting or use a small optional sample line filter.
- Warm-Up Time: Allow the instrument to warm up for at least 30 minutes, but more than one hour is preferred for optimal accuracy.
- Function Control: Use the front panel function control to access the UV-100’s internal microprocessor. This control allows you to select various functions and set parameters for your specific application.
Data Output Options
The Model UV-100 Ozone Analyzer provides multiple ways to output data:
- Data Readout: Ozone readings are continuously displayed on the LCD. The data is updated every 10 seconds.
- Output to External Equipment: The UV-100 offers 0-2.5 VDC and 4-20 mA analog outputs, which can be connected to external devices for control or monitoring.
- USB and Serial Output: Data can be transmitted to a computer through a USB port or a serial port. This allows for real-time data recording and monitoring.
Calibration
The UV-100 is calibrated using a reference instrument with traceable calibration to NIST standards. The instrument is calibrated to be pressure (P) and temperature (T) compensated for accurate measurements.
Application Examples
The Model UV-100 has a wide range of applications, including:
- Remediation: It can be used to control ozone generators for mold remediation, ensuring safe and effective treatment.
- Cold Condensing Environments: In applications where low temperatures and humidity are present, the UV-100 can be used with extended sample tubing and moisture traps to protect the instrument from condensation.
- Long-Term Data Logging: The UV-100 is capable of long-term data logging with the help of data loggers such as the Eco Sensors DL-3, allowing for continuous monitoring and recording of ozone levels.
Conclusion
The Model UV-100 Ozone Analyzer by Eco Sensors, Inc. is a versatile and reliable instrument for ozone measurement. Its compact design and multiple output options make it suitable for various applications, from remediation to long-term data logging. By following the provided instructions and understanding its features, users can take full advantage of the UV-100 for their ozone measurement needs.
