GLI E53A4A1N Conductivity Analyzer

Description

GLI E53A4A1N Conductivity Analyzer

Product Dimensions：

The GLI E53A4A1N (often branded under Hach / GLI International) is a high-performance Electrodeless (Inductive) Conductivity Analyzer/Controller. It belongs to the renowned GLI 53 series, specifically designed for industrial water quality monitoring where traditional sensors might fail due to fouling or corrosion.

Below is the detailed product information in English:

1. Product Description

The GLI E53A4A1N is a microprocessor-based analyzer used with electrodeless conductivity sensors. Unlike contacting sensors, this model uses inductive technology, making it ideal for measuring high-conductivity liquids, chemically aggressive solutions, or “dirty” samples that would typically coat or corrode metal electrodes.

2. Technical Parameters (Specifications)

3. Product Advantages

• Non-Contacting Measurement: Since the sensor does not have exposed metal electrodes, it is immune to “electrode coating” and polarization, significantly reducing maintenance.

• High Durability: The NEMA 4X enclosure provides superior protection against harsh environmental conditions and chemical vapors.

• Flexible Control: Equipped with four relays and dual analog outputs, allowing for complex control logic (e.g., controlling pumps/valves while sending data to a PLC).

• User-Friendly Interface: Features a simple, menu-driven setup in multiple languages (English, French, German, Spanish).

• Versatile Mounting: The hardware supports various installation types, making it easy to integrate into existing systems.

4. Key Considerations (Precautions)

• Sensor Compatibility: This controller must be used with GLI Electrodeless Conductivity Sensors (e.g., 3700 series). It is not compatible with standard contacting (2-electrode or 4-electrode) sensors.

• Calibration: For best accuracy, ensure the sensor is dry when performing a “Zero” calibration. When performing a “Wet” calibration, ensure the sensor is not touching the sides of the container.

• Wiring Safety: Always disconnect line power before opening the enclosure to avoid electrical shock.

• Cable Routing: Keep sensor cables away from high-voltage power lines to prevent electromagnetic interference (EMI).

5. Product Applications

• Chemical Processing: Monitoring concentration of acids (e.g., $H_2SO_4$, $HCl$) and bases ($NaOH$).

• Wastewater Treatment: Monitoring influent/effluent conductivity and industrial discharge.

• Cooling Towers & Boilers: Controlling blowdown cycles by monitoring dissolved solids.

• Pulp and Paper: Chemical recovery and white/black liquor monitoring.

• Metal Finishing: Pickling bath concentration and rinse water control.
