Fine Quality Online Water Hardness Meter Quality Assurance for Workplace
Product Overview
- The PXG-2085Pro from Shanghai Boqu Instrument Co., Ltd. is an online ammonium (NH4+) ion meter designed for continuous, real‑time monitoring of ammonium concentration in water.
- It uses an ion‑selective electrode (ISE) with a molded ammonium PVC membrane and a microcomputer‑based controller with a user‑friendly interface and local data recording.
Product Features
- Wide measurement range up to ~0.02 ppm–18,000 ppm with selectable resolution (0.01 / 0.1 / 1) and tiered accuracy (±0.01, ±0.1, ±1 ppm depending on range).
- Replaceable ISE membrane with >1 year working life under normal conditions; temperature compensation (Pt1000/NTC10K) and broad temp/ambient operating limits.
- Multiple outputs and controls: 2 × 4–20 mA, RS485 Modbus RTU, and 3 relays (high/low control and clean); local data logging for 1,000 records.
- Robust hardware: IP65 protection, anti‑electromagnetic interference and surge protection, power‑off data protection, and flexible installation (panel/wall/pipe).
Product Value
- Enables continuous, automated monitoring to improve process control, regulatory compliance, and rapid response to ammonium fluctuations.
- Lowers total cost of ownership through a long‑life, replaceable sensor membrane and reduced maintenance frequency.
- Onboard data logging and standard industrial outputs simplify integration into SCADA/DCS systems and support traceable reporting.
Product Advantages
- Extremely wide measurement range and high input impedance (>10^12 Ω) for accurate readings across dilute to concentrated streams.
- Durable, field‑serviceable sensor design and protective features (IP65, surge/EMI protection, power‑off save) for reliable long‑term operation.
- Versatile communications and relay control for process automation; global power compatibility (90–260 VAC) and multilingual interface.
- Backed by BOQU’s manufacturing and export network for supply reliability and after‑sales support.
Application Scenarios
- Online ammonium monitoring for municipal wastewater treatment plants and industrial effluent discharge control.
- Environmental water monitoring in rivers, lakes, and monitoring stations where continuous NH4+ trends are needed.
- Process control in chemical, food & beverage, aquaculture, and other industrial settings that require ammonium measurement.
- Any workplace or facility needing automated alarm/control actions based on ammonium concentration (e.g., dosing, cleaning cycles, regulatory compliance).
