Hazardous Area Online Process Hydrogen Sulfide Analyzer, CE




The H2S-625 is a cost-effective online hazardous area instrument for measuring hydrogen sulfide continuously with very little maintenance requirements.  The analyzer is certified by ATEX and IECEx for use in Ex db ib IIB+H2 T4 Gb.  Primary applications for this analyzer include natural gas, landfill, biogas 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, 2 relay contacts, multiple ranges and either a 12 – 24VDC or 100 – 240 VAC power input.

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.

The analyzer comes with an optional MODBUS RS485 RTU Bi-Directional Interface for digital communication.
