Fixed Toxic Gas Detector

The Filosha Fixed Toxic Gas Detector is a permanently installed point detector that safeguards personnel against harmful toxic gases. Using target-specific electrochemical cells, it measures gases such as hydrogen sulphide, carbon monoxide, chlorine, ammonia and sulphur dioxide at part-per-million levels, triggering alarms and control actions well below hazardous exposure thresholds for continuous, dependable protection.

Product Description

The Filosha Fixed Toxic Gas Detector delivers continuous, quantified monitoring of dangerous toxic gases that pose an acute risk to health even at very low concentrations. Employing high-selectivity electrochemical sensing cells matched to the target gas, the detector accurately measures hydrogen sulphide, carbon monoxide, chlorine, ammonia, sulphur dioxide and other toxics in parts per million. Readings and alarm states are transmitted to the plant fire-and-gas or control system, initiating warnings, ventilation or shutdown responses before workers are exposed to concentrations approaching occupational limits.

Engineered for permanent installation in demanding process environments, the detector is housed in a robust, corrosion-resistant enclosure suited to the heat, humidity and coastal salt-laden air common across the GCC and India. A local display and clear status indicators confirm live readings and alarm conditions at the mounting point, while standard analogue and digital outputs simplify integration with existing infrastructure. Plug-in sensor modules and non-intrusive calibration keep servicing quick and reduce downtime, and configurable alarm thresholds allow the device to be tuned to site-specific exposure limits. Positioned near known leak sources, sumps, compressor seals or enclosed work areas, the Fixed Toxic Gas Detector forms an essential layer of occupational-health protection, helping facilities protect their workforce and meet stringent safety obligations.
