Ensure safe and reliable turbidity monitoring in explosive or flammable industrial zones with our Flameproof Online Turbidity Meter. Designed for continuous operation in Zone 1 & Zone 2 hazardous areas, this rugged and accurate instrument delivers real-time turbidity readings while meeting stringent ATEX / IECEx / IS / PESO (CCOE) safety standards.  

Our Flameproof Online Turbidity Meter ensures your process runs smoothly and safely in hazardous industrial environments. Whether monitoring wastewater, process fluids, or critical rinse water, this instrument helps you meet safety standards, quality goals, and environmental regulations — all in one device. Engineered for industries handling flammable gases, vapors, or dust, such as oil & gas, chemicals, solvents, and pharmaceuticals, this turbidity meter is the perfect solution for applications where safety and performance cannot be compromised.

Product Overview

The Flameproof Turbidity Meter features an Flameproof enclosure housing an advanced optical sensor system that measures turbidity in NTU (Nephelometric Turbidity Units) with high accuracy. It continuously monitors the concentration of suspended particles or solids in liquids, helping operators maintain water clarity, product quality, and regulatory compliance.

It provides analog (4–20 mA) and optional digital outputs (RS485/Modbus), enabling seamless integration with existing PLC, DCS, or SCADA systems. With rugged construction, temperature compensation, it offers reliable performance in the most demanding environments.

Key Features

Explosion-Proof (Flameproof) Enclosure
Certified for hazardous areas (Zone 1 / Zone 2, IIC, T6), conforming to PESO/CCOE standards.

High Accuracy Turbidity Measurement
Measures turbidity from 0 to 4,000 NTU (depending on model), using advanced 90° scattered light or infrared detection for excellent sensitivity and repeatability.

Temperature Compensation 
Corrects for temperature-induced errors, ensuring stable readings in varying process conditions.

4–20 mA & RS485 Modbus Output
Standard industrial signal outputs for seamless integration into control systems.

Clear Digital Display
Flameproof front-panel display (or optional remote display) shows real-time NTU readings, temperature, and device status.

Alarm Relays 
High/low turbidity alarms with relay contacts for system interlock or process alert.

Self-Cleaning Sensor (Optional)
Optional sensor cleaning system (air purge or mechanical wiper) for applications with fouling potential.

Rugged & Weatherproof Design
IP65/IP66-rated flameproof housing suitable for harsh outdoor or corrosive environments.

Easy Field Calibration
User-friendly calibration using standard turbidity solutions (e.g., formazin).
