Searchpoint Optima Plus

Market-leading point infrared hydrocarbon gas detector with proven performance and sensitivity.

Built on 40+ years of point IR gas detection experience and an installed base of 100,000+ units worldwide, Searchpoint Optima Plus is certified for use in potentially explosive atmospheres. Its infrared detection principle delivers fast response and fail-safe operation to help protect people, maintain compliance, and maximize uptime.

Why it matters Reduced routine maintenance (vs. electro-catalytic detectors) lowers cost of ownership, while advanced diagnostics and false-alarm rejection help deliver high operational integrity.

Why Infrared

Fail-safe operation

Designed to provide dependable detection performance in safety-critical environments.

Fast response time

Quickly detects hydrocarbon gas hazards to support rapid action and safer operations.

Reduced routine maintenance

Lower ongoing maintenance burden compared with conventional catalytic technologies.

Immune to catalytic poisons

Well-suited for sites where catalytic bead poisons/inhibitors may be present.

Long operating life

Built for durability and long-term stability in demanding industrial environments.

Works in inert atmospheres

IR detection can be applied where inert conditions may limit other sensing methods.

Why Searchpoint Optima Plus

Proven global install base

Experience gained from 100,000+ units installed worldwide.

Wide hydrocarbon coverage

Detects a broad range of hydrocarbon gases, including many solvents.

How It Works

Optics Block

4-channel (dual compensated) optics-block helps compensate for environmental changes and long-term component drift.

Microprocessor

Controls operation and signal processing algorithms to support strong false-alarm rejection and integrity.

Heated Optics + Dynamic Heating Control

Heated optics monitored by smart electronics help prevent condensation while supporting power-saving features.

Remote Functional Gas Test

Optional factory-fitted gassing cell enables remote injection of functional test gas to validate performance.

Accessories & Protection

Sunshade / Deluge Protection

Supplied as standard to help shield the detector from extreme operational environments.

Storm Baffle

Optional accessory to reduce wind chill and salt/dust build-up in exposed high-wind applications.

Standard Weather Protection

Supplied as standard—balanced protection against water/dust ingress while maintaining response speed.

Dust Barrier

Additional internal barrier to reduce dust/contamination entering the optical path.

Gassing Cover

Enables confidence checks; close fit onto standard weather protection with no special tools required.

Calibration Cap

Required to achieve accurate calibration of the Searchpoint Optima Plus.
