Product Manual


The H2S-780 Portable Hydrogen Sulfide Analyzer combines a rugged portable design, integral sample system and updated electronics with SSO2’s precision H2S sensors. The result is a highly reliable and cost-effective design with easy to use interface.

The analyzer can come with two sets of ranges: The H2S-1x Sensor has ranges 0 – 10 ppm, 0 – 50 ppm, 0 – 100 ppm, 0 – 200 ppm.  The H2S-2x Sensor has ranges: 0 – 100 ppm, 0 – 500 ppm, 0 – 1000 ppm, 0 – 2000 ppm.

The sensor is based on the galvanic electrochemical fuel cell principal and is manufactured in house under a strict quality procedure.  The sensors are self contained and minimal maintenance is required – no need to clean electrodes or add electrolyte.  The precision sensors offer excellent performance, accuracy and stability while maximizing the expected life.

The analyzer comes with a built in sample system that includes a flow control knob and flow indicator.  Gas inlet is made via 1/8″ Compression tube fitting.

The electronics are feature packed with an easy-to-use menu interface.  The highlight of the advanced set of electronics include’s a USB output for data logging.  Data logging can be done via a removable USB flash drive and data can be taken in 1 minute intervals.  An 8 GB flash drive can store data for 50+ years.
