Open Path leak detector for larger rooms or fence line monitoring
The Photonic Innovations OPLD 4000 is the ideal ammonia gas leak monitor for protecting larger engine rooms or the periphery of a factory. Each OPLD can replace 2-4 point sensors. The device shines a low-powered non-dangerous laser beam across the room and collects it via a retroreflector. Featuring:
- No repeat calibration or sensor replacement required
- Low detection limit: 5ppm
- Fast response time: 0.5 - 4 second
- High accuracy and reliability: 1/2 of the detection limit
- Integrates with SCADA
- Ergonomic designP54 rating

Designed for rooms with large floor areas
The open path laser covers a much larger area as compared to point detectors. Instead of installing multiple point sensors just install one open path detector to get the job done.
Integrates with SCADA
The OPLD 4000 integrates with the central monitoring system in the plant room. Standalone modules with integrated alarms and sirens are also available.
