Description

The H2S-725 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 1 groups B, 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, 2 relay contacts, multiple ranges and a 12 – 24VDC 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 2 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.
