H2S Gas Generator

The Model PT301N H2S gas generator is a rugged and highly accurate microprocessor-based Hydrogen Sulfide gas generator. The unit uses an electrochemical generating cell and latest CMOS technology that makes it a compact and versatile system. The system provides push buttons to adjust the gas concentration and for system diagnostics. A low battery alarm is indicated by the Low Battery message displayed on the LCD. The system software constantly runs the diagnostic features to monitor the concentration of the gas generated. The diagnostic information is also displayed on the LCD. This information can be used to verify the concentration of the gas or troubleshoot the unit. The system also features a safe shut down mode to prevent any damage to the generating cell.

At 10 ppm the cell can generate H2S for 60 hours after which it can be replaced with a new cell in minutes.
