Honeywell Poole BH170RZUK PART No. : 2108B2001N Searchpoint Optima Plus Gas Detector
Product Overview
The BH170RZUK (Order Number: 2108B2001N), part of the Honeywell Searchpoint Optima Plus series, is a point-type infrared hydrocarbon gas detector designed specifically for industrial sites. It continuously monitors various combustible hydrocarbon gases, including methane, propane, and butane, within a 0-100%LEL range. It is suitable for explosive atmospheres in the oil and gas, chemical, pharmaceutical, and offshore platforms industries.
Core Advantages
• Accurate and Reliable: Utilizing dual-wavelength non-dispersive infrared (NDIR) technology, it achieves a long-term zero drift of <±1%LEL/year, eliminating the potential for poisoning and burnout associated with traditional catalytic sensors.
• Ultra-Fast Response: With a T90 of ≤ 4 seconds, it provides an alarm at the earliest sign of a gas leak, saving valuable time for emergency response. • Rugged and Durable: 316L stainless steel housing with IP66/67 + NEMA 4X protection, optional weatherproof dust cover and surge/heat shield, protects against salt spray, corrosion, high and low temperatures, and severe impact.
• Safety Certifications: ATEX / IECEx Ex d IIC T6…T4 Gb, compliant with EN 60079-0/1/31 standards; UL, FM, CSAus, CCCF, and marine certifications available.
• Intelligent Diagnostics: Built-in self-diagnostics monitor optical path blockage, drift, temperature, and voltage anomalies in real time, and output fault information via a 4-20 mA HART® digital signal or optional relay.
• Easy Maintenance: Zero and span calibration can be performed by one person without opening the cover; magnetic wand triggering or remote operation via a HART handheld communicator reduces downtime. Sensor modules can be quickly replaced in less than 5 minutes, reducing lifecycle costs.
