RKI Hydrogen Sulfide (H2S), 0-100 ppm, for Fixed & Sample-Draw Systems Plug-In Replacement Sensor
- SKU:
- ES-1537-H2S
Description
The RKI ES-1537-H2S is a genuine RKI Hydrogen Sulfide (H2S) replacement sensor designed for compatible RKI fixed and sample-draw gas detection systems. It provides a measurement range of 0–100 ppm H2S.
The ES-1537-H2S uses an amperometric 3-electrode electrochemical sensing principle and features a convenient plug-in CT-7 style design for field replacement. RKI specifies this sensor for numerous fixed-system configurations, including Direct Connect, S-Series, M2/M2A, M2A-XL, M-Series and compatible 35-3001 sample-draw systems.
RKI also identifies this exact sensor as the replacement sensing element in several H2S detector and transmitter assemblies, including the 65-2428 detector and compatible H2S transmitter assemblies.
Important: Always verify the complete detector or transmitter model before ordering. RKI manufactures several H2S sensors with similar ranges that are designed for different instruments.
