Description
Designed for industrial ammonia (NH₃) detection to ensure worker safety
Suitable for installation in production facilities, storage tanks, refrigeration systems, laboratories, and more.
The detector is equipped with an Ionic Ammonia sensor with a lifespan of over 5 years.
The sensor is resistant to humidity and can operate in low temperatures down to -40°C.
Detection Ranges (Ammonia):
- 0–100 ppm (TOC-102-NH3-1)
- 0–500 ppm (TOC-102-NH3-5)
- 0–5,000 ppm (TOC-102-NH3-50)
Dual Gas Detection Capability
This detector can measure two different gases simultaneously, thanks to its dual-sensor design:
- One sensor dedicated to ammonia
- Second sensor configurable for an additional gas of your choice
The detector features two independent channels, meaning each sensor operates separately—essentially providing two detectors in one unit.
Each channel includes a separate 4–20 mA analog output, allowing easy integration with external systems (e.g., fire detection systems or control systems).
Display & Status Indication
- Real-time gas concentration displayed on a color digital screen
- Green – Normal operation
- Red – Alarm condition
- Orange – Fault
Installation & Safety
- ATEX certified, suitable for hazardous areas (Zone 1 & Zone 2)
- Explosion-proof design
- Remote sensor capability via cable
Example:
For gases with different densities (e.g., hydrogen – lighter than air, LPG – heavier than air), one sensor can be mounted on the detector and the second remotely for optimal detection.
