The h2s meter is a fixed gas detection system that detects, monitors and transmits a continuous reading of the concentration of hydrogen sulfide in an ambient air sample. It is typically used in industrial settings where exposure to this toxic gas may occur. Most company procedures for monitoring confined space environments require personnel to wear portable H2S detectors and take action if the concentration of gas reaches an alarming level, typically 10 ppm averaged over one minute.

Most h2s meter devices use electrochemical sensors that convert airborne gas into an electrical signal, resulting in a readout of the concentration value in ppm. Depending on the sensor technology, the sensor can use principles such as amperometry, potentiometry or cyclic voltammetry to measure the airborne concentration of sulfide. The monitors typically display the concentration value on a LCD screen, and the alarm is triggered if the concentration crosses a threshold value.

Detecting Danger: The Functionality of H2S Meters in Hazardous Environments

A good h2s meter needs to be accurate and reliable. This is especially true in extreme temperature conditions and high humidity. The Crowcon HT h2s detector, for example, is designed to operate happily in these conditions with no temperature drift and very low moisture loss.

Personal gas monitors should be “bumped tested” on a regular basis to ensure that they are functioning properly. The bump test involves exposing the sensors to a known concentration of gas, such as 25 ppm of H2S, by connecting a bottle of cal gas via a length of tubing and a special clip to the device. The H2S monitor is then analyzed to see if the alarms are triggered, and the device is ready for further use.

An option is a contract that gives the buyer the right, but not the obligation, to buy or sell an asset at a specific price within a certain timeframe. Investors often trade options to acquire leverage, generate income or hedge against market volatility. Options are traded on specialized exchanges, like the Chicago Board Options Exchange (CBOE) and the American Stock Exchange (AMEX).
