Hazardous Area Hydrogen Sulfide Analyzer H2S-150-NG

Brand: Southland Sensing Ltd

The H2S-150-NG is a cost-effective online intrinsically safe instrument for measuring hydrogen sulfide continuously with very little maintenance requirements.  

The analyzer is designed for use in Class 1, Division 2 groups C, D.  

Primary applications for this analyzer include natural gas, landfill and other industrial applications.

The electronics are highly reliable and feature packed with a very easy-to-use MENU interface.  

No need to lug an expensive laptop into the field to configure the unit.  

Electronic features include 4 – 20mA or 1 – 5 VDC, multiple ranges and a 12 – 24VDC power input (2-wire loop configuration is optional; MODBUS RS485 ASCII is optional).

The H2S sensor is based on the galvanic electrochemical fuel cell principal.  

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 3 optional sensors, the H2S-1x has four ranges 0 – 10 ppm, 0 – 50 ppm, 0 – 100 ppm, 0 – 200 ppm.  

The H2S-2x has 0 – 100 ppm, 0 – 500 ppm, 0 – 1000 ppm and 0 – 2000 ppm. The H2S-3x has 0 – 1000 ppm, 0 – 2000 ppm, 0 – 5000 ppm, and 0 – 10000 ppm.
