The H2S QUICK CHECK is a hand-held device designed to spot check the H2S levels in natural gas pipelines as well as verify the H2S concentration in calibration gas bottles. The sample goes in the “Sample In” through the H2S sensor housing and out the “Sample Vent” fitting. Always use extreme caution when venting. A charcoal filter with tubing should be used to absorb any H2S that is vented from the sensor vent fitting located on the top of the monitor. Operators should routinely verify the charcoal is still absorbing by using an H2S monitor at the outlet. The Quick Checks use an electro-chemical sensor to measure the levels of H2S. The sensor lasts approximately 2 years. Depending on how often the unit is used calibration should be done routinely. Calibration as well as sensor replacement can be done in the field or sent back to the factory. A Procell by Duracell 9v battery (PC1604 Alkaline Manganese Dioxide ) is used to power the unit. The 9V battery should never be replaced in a hazardous area.
