Model 3000RS
The AMI model 3000RS portable analyzer is the industry standard analyzer
for spot checking and trouble-shooting trace hydrogen sulfide in gas
systems.
Hydrogen sulfide is a “sticky” gas – it sticks to the
surface of all the tubing and sample components. The 3000RS minimizes
the length of the sample plumbing by making use of the AMI patented cell
block principle, modified for use with the H2S sensor.
The analyzer can be set up to monitor a sample while
logging the readings so that they can be examined later, using the
“datalog” capability built in. When enabled it will log the hydrogen
sulfide readings every minute, as well as the temperature and battery
voltage. It also tracks the calibration history and the sensor usage.
It responds primarily to hydrogen sulfide. It has
minimal response to other electrochemically active gases such as carbon
monoxide and hydrogen, but it should not be used if those gases are a
significant percentage of the background gas.
The AMI model 3000RS is built tough with a welded
steel case, and a special version of our patented cell block to provide
the sample handling required. All the sample handling components are
directly mounted on or in the block, with connections made via drilled
passages. Built into it is a needle valve so that flow can be adjusted.
As usual with AMI analyzers the sensor itself is immediately
accessible behind the front panel and can be replaced simply and without
needing any tools.
This analyzer is intrinsically safe and has been
formally approved by CSA International to UL and CSA standards as
meeting requirements for Class 1, Div. 1, Groups B,C,D with a flammable
gas sample. It is battery powered with up to 350 hours of life, and it
contains a data logger so that it can be left monitoring a gas system
for several days in order to catch intermittent hydrogen sulfide spikes.
The range over which it logs can be adjusted for best sensitivity.
When completed, simply plug it into a PC through the USB port and use
the AMI software to display the data.
