Honeywell 2108B2051N Searchpoint Optima Plus Marine MED Infrared Hydrocarbon Gas Detector

Product Description

The 2108B2051N is Honeywell Analytics Searchpoint Optima Plus point infrared gas detector with Marine MED certification. It adopts non-dispersive infrared (NDIR) principle to detect flammable hydrocarbon gases such as methane, propane. It outputs 4–20mA+HART signal, suitable for marine vessel, offshore platform and explosive hazardous area. Compared with catalytic bead sensors, it features longer service life and lower maintenance frequency, and supports fail-safe fault diagnosis.

FAQ

Q: What is the difference between 2108B2051N and 2108B2001N?
A: 2108B2051N is MED marine certified version; 2108B2001N is standard ATEX industrial version without marine certificate.

Q: What gas can it detect?
A: It is for hydrocarbon gases, mainly methane, propane, butane and other flammable hydrocarbon mixtures.

Q: Is this detector discontinued?
A: Searchpoint Optima Plus series is mature product, still available for spare supply, refurbished and surplus units are widely traded.

Q: Can it connect to XNX gas transmitter?
A: No, this is a complete point gas detector, not a POD sensor module for XNX series.
