Breathe Easy. Monitor Precisely.

Intelligent, continuous air quality monitoring engineered to withstand the most demanding industrial and mining atmospheres.

Laser Scattering Precision

Explosion Proof

Seamless Integration

Features

Triple-Stage Particulate Tracking

Simultaneously monitors PM1, PM2.5, and PM10 levels to provide a comprehensive profile of respirable and inhalable dust.

Industrial-Grade Laser Scattering

Features an advanced laser sensor that offers outstanding sensitivity and stability compared to traditional sampling methods.

High-Visibility Colour LCD

Equipped with a bright, clear display optimized for real-time readings in the low-light and high-dust conditions typical of underground mines.

Intelligent System Integration

Standard 4–20mA and RS485 outputs allow for direct communication with DCS, PLC, and RTU host control systems.

Automated Relay Control

Built-in relay output can automatically trigger dust suppression sprays or increase ventilation when thresholds are breached.

Explosion-Proof & IP65 Rated

Housed in a heavy-duty aluminium shell with Ex db IIC T6 Gb certification, built to survive water, dust, and extreme pressure.

Comprehensive Electrical Protection

Engineered with built-in safeguards against over-voltage, lightning strikes, short circuits, and reverse polarity.

Proactive environmental monitoring

that turns invisible particulate risks into actionable, real-time safety data.

Engineering Features

Natural Diffusion Sampling

Efficiently samples ambient air without the need for external pumps, reducing mechanical wear and maintenance.

Rapid Response Time

Ensures that dangerous spikes in dust concentration are detected and alerted within seconds of occurrence.

Remote Control Setup

Allows for safe configuration and calibration adjustments without needing to open the enclosure or halt production.

Use Cases

Underground Stoping

Continuous monitoring of respirable dust levels at the face to ensure ventilation systems are effectively protecting workers.

Automated data logging via RS485 ensures shift supervisors have a 24-hour history of air quality for compliance reporting.

Immediate activation of local audio-visual alarms during a ventilation failure, providing life-saving seconds for evacuation.
