Integrated H2S Detection Solution
The OleumTech® H Series Hydrogen Sulfide (H2S) Gas Detection Transmitter is an RS485 Modbus interface solution for continuously monitoring air quality and generatong alarms when H2S concentration levels exceed user-configured setpoints to ensure a safe working
environment. The transmitter is equipped with a replaceable H2S sensor module enclosed in a robust 316 stainless steel housing with a steel mesh filter. A dust/splash guard is also included for added layer of protection. The H2S Transmitter provides helpful sensor maintenance tags like bump test count, total days since last successful bump test, and calibration. In addition, the HW5000-H2S Transmitter provides two solid state relay outputs for alarm annunciation.
Reliable, Scalable and Safe
The local user interface allows for device configuration and instant data access. Bump tests and alarm acknowledgments can be performed using a single external button.
The OleumTech H Series H2S Transmitter, HW5000-H2S, is Intrinsically Safe and is certified for use in Class I, Division 1 hazardous locations. The instrument can be ordered with 12 or 24 V IS Barrier Boards. The OleumTech HW5000-H2S is a natural choice for a wide variety of oil, gas, water, wastewater, and other mission-critical applications that require a high level of accuracy and reliability.
