    Model 3010BR Hydrogen sulfide Analyzer Introduction Using the same advanced engineering perfected in the 2010BR trace oxygen analyzer, AMI has produced an equally effective hydrogen sulfide analyzer. Instead of having to use clumsy, unreliable lead acetate tape, or alternatively very expensive and delicate laser diode analyzers, AMI has applied a unique electrochemical sensor to a modified version of the proven platform of the 2010BR to produce an equally effective hydrogen sulfide analyzer.

    (which slows the response of this kind of analyzer). AMI uses a version of the patented “Cell block”, a machined block of nickel-plated aluminum that integrates all of these functions in one compact, and reliable package.

  • Page 7: Sensor Warranty

    The sensor has an expected life of three years, and it is warranted to operate for a period of one year on a pro-rated basis. If the sensor ceases to operate correctly before this time has elapsed, contact AMI for a return authorization for evaluation.

    Sample conditions – if your sample is hot and wet, you will need to keep water from condensing in the sample line or analyzer. The AMI demister brings hot and wet gases back to ambient temperature and allows the condensation and entrained liquids to fall back into the pipeline (no draining is necessary, unlike a coalescing filter which requires routine maintenance).

    There is an RS485 connection running ModBus available from the explosion-proof section. This may be wired up permanently. There is also a USB port in the explosion-proof section that may be used occasionally by removing the explosion-proof cap. If so, the area MUST be declassified first.

    (only the Alarm hold off button performs a function, though other buttons will show settings but won’t allow them to be changed). If the front panel controls don’t seem to work, use the AMI User Interface to change the security settings.

  • Page 18: Output Ranges

    If the range changes back again after you let go, the security level must be set to full or span only security. In this case change the security level with the laptop and the AMI User Interface program. Alarm Set Points The alarm set points can be viewed and changed (if security allows) from the front panel.

    View the Span Factor: The model 3010BR has a “Span Factor” feature. It can be displayed on the LCD by pressing the UP arrow by itself (when the analyzer is in normal operation, meaning not in a function such as spanning or setting the alarms).

    10,000 Ohm load. Either will saturate at more than 125% of the nominal full scale range. Using AMI software you can set the output to 4mA, 12mA and 20mA(or 1V, 3V and 5V), and adjust the internal settings to calibrate these values so as to get the most accurate possible transfer of information to a recording or computing device.

    It is in the left hand position for 4-20mA, and the right hand position for 1-5V. If you switch between the two options the internal calibration will be fairly close but not perfect, so it may be necessary to use the AMI User Interface to make the output exact. AMI Analyzer Manual...

    Advanced Features and Communications Communication Program: The analyzer supports both the industry-standard ModBus protocol running on an RS485 loop, and the AMI User Interface software connected via a USB port. If the USB connection is detected the ModBus connection will be disabled.

  • Page 25: Maintenance And Troubleshooting

    Maintenance and troubleshooting Maintenance: The model 3010BR is virtually maintenance free other than for periodic calibration and occasional sensor replacement. Periodic Calibration: The analyzer should be calibrated about once every month to obtain the best accuracy. The sensor typically declines in sensitivity by less than 1% of full scale per month, so a monthly calibration is usually satisfactory.
