Online Ion Meter Ion Meter for Workplace Factory Direct Supply
Product Overview
- The PXG-2085Pro is an online calcium ion (Ca2+) meter using ion-selective electrode (ISE) technology for continuous, real-time monitoring of calcium in water.
- Built as a microcomputer-based controller with a user-friendly interface, backlit dot-matrix display and local data logging.
- Rugged industrial design with IP65 protection, multiple installation options (panel/wall/pipe) and universal power input (90–260 VAC).
Product Features
- Measurement range: approx. 0.02 ppm to 40,000 ppm (0–40,000 mg/L), with multi-step resolution (0.01 / 0.1 / 1) and high accuracy tiers (±0.01 / ±0.1 / ±1 ppm depending on range).
- Replaceable molded PVC calcium ISE membrane with >1 year working life under typical conditions.
- Temperature compensation (Pt1000/NTC10K), temperature range -10 to +130 °C, input impedance >10^12 Ω.
- Outputs: 2 × 4–20 mA (max load 500 Ω), RS485 Modbus RTU communication, and 3 programmable relays (high/low control, clean) with adjustable delay (0–120 s).
- Local data recorder (1000 records), anti-electromagnetic interference and surge protection, power-off data-save function, language options (English/traditional Chinese).
Product Value
- Enables continuous, automated calcium monitoring for process control and regulatory compliance, replacing manual sampling and lab testing.
- Long-lived, replaceable sensors reduce maintenance frequency and costs.
- Multi-output control and data-logging support integration with PLC/SCADA systems for automated dosing, alarms and trend analysis.
- Robust electrical protection and wide power compatibility minimize downtime in industrial environments.
Product Advantages
- Very wide measurement span suitable for low to very high calcium concentrations.
- High input impedance and accurate ISE-based measurement for reliable results.
- Flexible communications and control options (4–20 mA, Modbus, relays) for easy system integration.
- Durable, low-maintenance sensor design and IP65 enclosure for harsh workplace/factory conditions.
- Built-in data logging and anti-interference features increase measurement security and traceability.
Application Scenarios
- Water softeners and boiler/feedwater monitoring.
- Wastewater and effluent treatment plants for discharge control.
- Industrial process control (e.g., electroplating, chemical plants) where calcium concentration affects quality.
- Environmental monitoring and lab/field stations requiring continuous calcium surveillance.
- Aquariums, aquaculture systems and other controlled aquatic environments.
