Jerome® Communications Software (JCS)

The Jerome® Communications Software (JCS) operates with the Jerome® 431 Mercury Vapor and Jerome 631 Hydrogen Sulfide Analyzers that have the "Communications Configuration" option installed. The software can control instrument sampling for unattended continuous operation, collect data, graph this data in real time and perform statistical analysis.

The software can also program the Jerome® Data Logger, AZI P/N 6100-0010. This optional accessory enables data storage during manual sampling or portable automatic sampling without being attached to a computer. The data logger initiates automatic sampling, triggers alarms and stores data. The logged data may then be downloaded to the computer when it is convenient.

The JCI software is menu-driven and easy to use. Each display screen is designed for clarity with self-explanatory menu options, such as "Operate Instrument" or "Display Stored Data." Select menu options using either a mouse or a track ball pointing device or a standard keyboard. The user creates records, or files, for computer storage of collected data. Data is easily retrieved for later viewing, graphing, printing or editing with spreadsheet or word processing software, (not provided). Data can be used for ongoing record keeping or for fulfilling local regulatory requirements.

Before using this software, familiarization with the operation of the Jerome® Hydrogen Sulfide Analyzer or Mercury Vapor Analyzer is important. Also, prior to installation of this software, you should be familiar with the personal computer and operating system you are using. If you have any questions about how to proceed, call AZI Customer Service at 800.528.7411 or 602.470.1414 or send an email to support@azic.com for assistance.

H2S Management by Monitoring

H2S is a common problem in the waste management industry. The unpleasant odor is not only a nuisance to customers and citizens, but is also physically harmful. H2S is a key ingredient in the deterioration of concrete (literally the foundation of this industry). There are methods commonly used to remove H2S from confined areas, but their high cost makes them impossible to implement everywhere. So, in order to manage the problems effectively, you must measure H2S reliably.

Arizona Instrument LLC manufactures the Jerome® line of H2S analyzers. These instruments are used to pinpoint problem areas within a system so the appropriate action can be taken. Because the human nose is very sensitive and can detect H2S at .008 ppm (parts per million), some companies feel that a nose test will tell them when and where they have a problem. Unfortunately H2S desensitizes the olfactory and after a few minutes that individual will not be able to smell the chemical anymore, making this method ineffective. People are incapable of detecting multiple problems at one time, and it is harmful to the individual. Jerome® analyzers read between .003 ppm and .050 ppm measuring, at levels where the H2S is dangerous for people and concrete. Without a Jerome® H2S analyzer it is not possible to assess problems for maximum savings of time and money.

AZI at a Glance

Arizona Instrument is an ISO 9001:2000 registered company that designs, manufactures, and markets Computrac® precision moisture analysis instruments and portable and fixed Jerome® gas analyzers. We provide complete pre- and post-sale customer service including application development, training, and instrument calibration and repair.

Computrac® Vapor Pro® moisture analyzers detect moisture levels as low as 10 ppm, or 10 mg, in samples as small as 10 mg utilizing moisture-specific sensors to eliminate volatile interferences. Computrac® MAX® moisture analyzers measure moisture content as low as 0.005 percent in as few as 3 minutes. These instruments are durable, easy to use, and equally suitable for the production floor and the laboratory.

Utilizing patented gold sensor technology, the Jerome® 631-X measures hydrogen sulfide concentrations of 3ppb to 50ppm, while the Jerome® 431-X mercury vapor analyzer detects concentrations from 0.003 to 0.999mg/m3, all in just 13 seconds. The Jerome® 860 hydrogen sulfide monitor provides automatic, unattended, long-term monitoring of hydrogen sulfide gases in contained or hard to reach areas. The compact, battery powered 860 is water resistant and intrinsically safe. Accessories include a field test kit for easy verification of instrument calibration, a data logger for data acquisition and instrument programming, and software for connecting the analyzers to computers.

Hydrogen Sulfide Gas

If you wait for a warning, it may be too late

Hydrogen sulfide is a powerful and deadly gas which smells like rotten eggs at low concentrations and has a sweet smell at high concentrations. But workers should not rely on the smell as a warning. At high concentrations H2S may overcome one's sense of smell. The result could be instant death. Long exposure to low concentrations will also deaden the sense of smell.

What it is

H2S is explosive - it will ignite and explode when subjected to a spark or ordinary flame - in any concentration from 4% to 44% of the air. It is also soluble in water and oil, so it may flow for a considerable distance from its origin before escaping above ground or in an entirely unexpected place. Because the vapor (gas) is heavier than air, it may travel for a long way until ignited and then flash back towards the source.

Where is it found?

Hydrogen sulfide is found in large amounts in natural gas and petroleum. Any worker involved in extracting gas and petroleum from the ground, or in storing, transporting or processing gas is at risk from exposure to H2S Hydrogen sulfide exists in solution in crude oil, and workers are exposed when the gas begins to "pass off" as it reaches the surface or comes into contact with air. This can occur at any point, including all stages of the refining operation, and it is accelerated by heat or hot weather.

H2S Sources

H2S is found widely in industry and few workers are warned of its dangers or their exposure. It is formed by the decomposition of organic materials, so it is found in natural gas and oil, in mines, wells, fertilizers, sewers, and cesspools. It is given off as a by-product in the manufacture of rayon, synthetic rubber, dyes and the tanning of leather.

Health Effects of H2S acute exposure

First of all, and most important, H2S can kill you. The extent of acute poisoning danger depends on the concentration of H2S in the atmosphere.
When you breathe in H2S, it goes directly through your lungs and into your bloodstream. To protect itself, your body "oxidizes" (breaks down) the H2S as rapidly as possible into a harmless compound. If you breathe in so much H2S that your body can't oxidize all of it, the H2S builds up in the blood and you become poisoned. The nervous centers in your brain which control breathing are paralyzed. Your lungs stop working and you are asphyxiated - just as though someone had come up and put their hands around your neck and strangled you. A worker can be overcome by H2S and lose consciousness in a few seconds; luckily if he is rescued in time and is given artificial respiration within a few minutes, the worker may recover. Either artificial mouth-to-mouth or an oxygen supply system of resuscitation will work if it is done in time, because, with an adequate source of oxygen and no further H2S intake, the body will quickly break down the H2S still in the blood.

This is acute poisoning. It can occur with no warning at all, since even the sense of smell may be overcome, and it can be fatal within a few seconds.

Although acute poisoning is deadly if it is not caught in time, when caught and treated it is reversible and this is why rescue attempts with proper safety equipment are so important.
Recent evidence has shown irreversible brain damage from acute high doses. READ MORE
