Frequently Asked Questions

1. How does your analyzer work?(s=1)
As soon as the customer uses the word analyzer - stop! Eventually the subject about the principle of operation of the catalytic bead or other sensor type can be broached. However, it is more important to first determine whether the customer really needs an analyzer or a gas detector, so that both you and the customer know how to proceed. These are gas detectors, not analyzers.

More than a few customers have been known to try to purchase an analyzer for the price of a gas detector.

Consider the following.
Suppose an experiment was set up where a cylinder of gas was set in the corner of a small room where dozens of gas detectors were installed, and then the valve of the cylinder was opened, thereby simulating a small gas leak. What would happen? Each detector would have a different reading at any point in time! Those detectors closest to the cylinder would detect the gas first, while those furthest away might not detect any gas for several minutes. The gas concentration will probably never become homogeneous throughout the room.

Which detector is therefore "right"? Which one is the most "accurate"?. This example will hopefully open the customer's eyes to what gas detectors are intended to do. If the customer has a different purpose, there is a good chance of a mis-application by using gas detectors.

2. What are the differences between gas detection, monitoring and analysis?(s=4)
There seems to be some overlap in detector, monitor and analyzer responsibilities in that they all measure gases in some respect. Detectors are perhaps more reactive in that they detect situations outside normal operating parameters and are set up to alarm. Monitors also are set up to alarm, but their role is to determine which gases are in the stream being measured and in what quantity they are present. Analyzers provide analysis of what is found and can not only log this information, but can download it to a computer where further analysis and record-keeping can be performed.
