Description
Description
Overview
GAOTek’s PXG-2085Pro delivers precision control by measuring ammonium concentration (NH₄⁺) continuously using ion-selective electrode (ISE) technology. It features rugged IP65-rated housing and flexible mounting—panel, wall, or pipe—for demanding industrial environments. Communication via RS-485 Modbus and dual analog outputs (4–20 mA) plus three relay alarms ensures seamless integration into automation systems. With extensive data logging, customizable OEM options, and a one-year warranty, it’s engineered for robust, long-term deployment.
Features
- Ion-Selective Measurement: Targets NH₄⁺ using advanced ISE technology, with replaceable membranes for reduced maintenance cost.
- Dual Output Modes: Offers two isolated 4–20 mA outputs (max load 500 Ω) and RS-485 Modbus RTU communication.
- Alarm Control: Equipped with 3 relays for high/low control and auto-clean functions.
- Data Logging: Stores up to 1,000 historical measurement records for auditing and diagnostics.
- Temperature Compensation: Supports PT1000 or NTC10K compensation within –10 °C to +130 °C.
- Broad Ion Compatibility: Supports multiple ion types, including F⁻, Cl⁻, Ca²⁺, NO₃⁻, NH₄⁺, NH₃, K⁺, CO₂, Cu²⁺, S²⁻, and more.
- Durable Construction: IP65 protection prevents dust and water ingress; suitable for harsh industrial environments.
- Power Range: Operates on 90–260 V AC (alternatively 24 V DC in some models).
Applications
- Real-time NH₄⁺ monitoring in wastewater treatment and effluent control
- Lab or process control in aquaculture, fish farming, and industrial water systems
- Integration into automated chemical, power, and semiconductor plants
- Food & beverage, environmental, and municipal water quality systems
