Online TDS / Conductivity Meter with Flameproof Enclosure – Safe, Accurate Monitoring in Hazardous Areas

Ensure safe and precise conductivity and TDS measurement in hazardous environments with our Online TDS / Conductivity Meter with Flameproof Enclosure. Built for continuous monitoring in explosive or flammable zones, this industrial-grade device combines high accuracy with certified flameproof protection to deliver reliable water quality and process control where safety is paramount.

Product Overview

Designed for Zone 1 & Zone 2 hazardous areas, this flameproof TDS/Conductivity meter is housed in an explosion-proof enclosure compliant with ATEX / IECEx / IS / PESO (CCOE) standards. It provides real-time monitoring of conductivity and total dissolved solids (TDS) in process water, effluents, and chemical solutions.

Equipped with temperature compensation (TC), analog output (4–20 mA), and optional Modbus RS485 communication, the device integrates seamlessly into existing automation systems such as PLC, DCS, or SCADA. The rugged, corrosion-resistant construction ensures long-term operation in demanding industrial settings.

Key Features

• Flameproof Enclosure (Explosion-Proof Design) : Certified for use in hazardous gas zones (Zone 1/Zone 2, IIC, T6). Conforms to ATEX / IECEx / IS / PESO safety standards for explosive atmospheres.
• Dual Parameter Measurement : simultaneously monitors and displays Conductivity (µS/cm or mS/cm) and TDS (ppm), with high precision and fast response.
• Automatic Temperature Compensation (ATC) : Compensates for temperature variations in the process to maintain measurement accuracy across wide temperature ranges.
• Wide Measuring Range : Conductivity: 0–200 mS/cm
• TDS: 0–100,000 ppm : Selectable cell constants (K = 0.1, 1.0, 10.0) for different applications
• Large LED / LCD Display : Bright, backlit display for real-time readings of conductivity, TDS, and temperature — visible even in outdoor or dimly lit areas.
• 4–20 mA Analog Output + RS485 (Optional) : Easily connects to control systems (PLC/SCADA/DCS) for real-time monitoring and automation.
• Alarm Relays (Optional) : Programmable high/low conductivity or TDS alarms with relay outputs for process interlocks or safety alerts.
• IP65 / IP66 Weatherproof Housing : Resistant to dust, moisture, and harsh chemicals — ideal for both indoor and outdoor industrial use.
• Easy Field Calibration : Supports one-point or two-point calibration using standard conductivity solutions.
• Mounting Options : Wall, pipe, or panel mounting available for flexible installation in industrial sites.
