10ppm to get a good reading. Any electrochemical sensor will take some time to do this, depending on how long it has been exposed. AMI sensors are the fastest in the industry, and the AMI cell block is very effective at purging air from the sensor, but after a one minute air exposure even an AMI sensor/analyzer combination will take up to 15 minutes to get down to 10ppm. - Page 6 Trace oxygen is measured using a disposable electrochemical sensor that is specific to oxygen. It wears out in use like a flashlight battery, and thus has to be replaced occasionally, typically once per year. AMI makes a proprietary sensor line that gives particularly good performance in aggressive industrial applications – the T-2 is...

Page 7: The Model 1000Rs
The Model 1000RS Figure 1 Front view The Model 1000RS provides all the features required to make measuring and spot checking trace oxygen levels simple. It includes a complete sample system together with a state-of-the-art electronics package that provides USB connectivity, datalogging of the O2 readings, battery voltage and temperature, and many other advanced features such as calibration history and sensor life indication. - Page 8 Charging socket USB Connector Charging LED Analog 0-1V Output Sample exhaust Sample Inlet Figure 2 Back view On the back the analyzer is a quick-disconnect fitting for the sample inlet. It is provided so as to minimize wear on the fitting - it is not required to seal gas in the analyzer. Conventional compression fittings cannot be used more than a few times without damaging them to the point that they leak enough to cause erroneous readings.
- Page 9 The sensor is warranted to operate for a period determined by its class. If the sensor ceases to operate correctly before this time has elapsed, return it to AMI for evaluation. If there is any evidence of defective material or workmanship the sensor will be replaced on a pro-rated basis.
- Page 10 Using the Analyzer Introduction: The AMI model 1000RS analyzer is meant to be used for spot checking gas samples for trace levels of oxygen contamination. “Trace” means oxygen at levels from zero to about 1000ppm. It does provide percent ranges but these are intended only to allow for air calibration if desired.

Page 11: Powering Up The Analyzer
Powering up the analyzer: Press the On/Off selector button on the right side of the front panel to turn the analyzer on or off. It will show “Init” for a few seconds, then possibly a high value, and then the reading will drop to zero and climb up to whatever the sensor is currently measuring. -
Page 12: Sensor Life
It also stores the time and date of the reading set, and the battery voltage and the temperature. All of these can be recovered from the analyzer using the AMI user interface program and the USB connection on the back of the analyzer. -
Page 13: Sample Line Connection
Figure 3 Sampling from a pipeline (demister not shown for clarity) Sample Line Connection: The sample is brought into the “quick connect” fitting on the rear of the analyzer. We use this kind of fitting because it can be made and unmade many times without damage, unlike a compression fitting. If you are using the flexible tubing supplied as an optional accessory, simply plug it into this fitting. -
Page 14: Valves
We strongly suggest that you use the flexible tubing AMI supplies. It has very low diffusion, but it remains flexible even at low temperatures. Stainless tubing can become a real problem after a while, particularly after it work-hardens. Be aware that most plastic tubing will allow oxygen to diffuse into itself at a fairly high rate; typical PVC tubing will add about 1ppm oxygen for every foot of tube at a flow rate of 1 SCFH at 70F. -
Page 15: Measuring A Sample
Measuring a sample: Plug the sample line into the quick connect fitting located on the back of the analyzer, and allow gas to flow with the On/Off selector valve in the Off position. Use the needle valve (the knob in the center of the On/Off selector valve) to control the flow to about 1 SCFH. - Page 16 “Bat Lo” Shows alternately “Bat” then “Lo” with the Batteries are low, but OK for a while. Recharge reading, every ten seconds soon. Batteries are too low for operation (dead). They “Ded” Shown continuously must be recharged Although the batteries are charged when the analyzer leaves the factory, NiCd batteries self-discharge and they may be discharged by the time you use it.

Page 18: Calibration Procedure
Figure 4 Calibrating the analyzer Calibration Procedure: A new unit is supplied with its sensor installed, and has been calibrated at the factory. It is generally not necessary to calibrate it for a month or so after receiving it. However it should be calibrated on a four to six week basis for best performance. -
Page 19: Air Calibration
disadvantage is that it takes the sensor quite a long time to come back down to low levels after exposure to air, and you will need a low level gas such as nitrogen or your sample gas to purge it when you are done. If you don’t purge the sensor after an air calibration, it will become extremely sluggish to the point that it is easier to replace the sensor than to wait for it to recover! Calibrating with a low level gas avoids the problem of saturating the sensor, but presents its own set of... -
Page 20: Low Level Gas Calibration
Low level gas calibration You can use a gas such as 80ppm oxygen in nitrogen to perform a low level calibration. This level of oxygen is convenient for the gas manufacturers to make, and has been found to be optimum in most cases. Make sure you are using a pressure reducing regulator with a stainless steel diaphragm –... -

It doesn’t matter if you leave it logging all the time – you will just have a lot of uninteresting data points logged if you do. You can set the log period – the time in between when it stores data points – with the AMI User Interface program. -

has been in operation, how much oxygen it has been exposed to, and how long it has been exposed to temperature extremes. Of course it can only do this while it is turned on, but it does track the total length of time it was been out of operation as well, so you can get an idea of the state of the sensor. -
Page 23: Periodic Calibration
Maintenance and troubleshooting Maintenance: The AMI oxygen analyzer is virtually maintenance free other than for periodic calibration and occasional sensor replacement. Periodic Calibration: The analyzer should be calibrated about once every four to six weeks to obtain the best accuracy. The sensor typically declines in sensitivity by about 1% per month, so this frequency is usually satisfactory. -
Page 24: Sensor Replacement
Sensor Replacement: CAUTION: The sensor contains an acid liquid about as strong as vinegar. Do not allow this to come into contact with your skin. If it does, immediately flush the affected area with water for a period of at least 15 minutes. Refer to the Material Safety Data Sheet provided. Dispose of leaking or used sensors in accordance with local, state and federal regulations. -
Page 25: Common Calibration Errors
Regulator and gas line not properly bled. • Not allowing long enough for the sensor to come down to its reading from air exposure. • Use of any plastic tubing (should be the special AMI tubing or stainless steel tubing). Page 23 Advanced Micro Instruments, Inc. -
Page 26: Sensor Going Negative
If it doesn’t work, or if the sensor immediately fails again, then it must be replaced. If it happens within the warranty period, return it to AMI for credit. Page 24... - Page 27 Procedure: Connect the analyzer to a source of low level gas, such as nitrogen or your sample. 2. Turn the On/Off selector valve to the Off position. 3. Open the cell cap, and remove the sensor. 4. Let the sensor sit in air for about a minute. 5.
