Latest Algae Online Analyzer for Irrigation
Product Overview
- Latest Algae Online Analyzer for Irrigation (BOQU TNG‑3020) — an online Total Nitrogen (TN) analyzer designed for continuous, automatic monitoring of nitrogen in water.
- Uses resorcinol spectrophotometry; simple operation with no sample pretreatment — the sample riser can be inserted directly into the water stream.
- Wide selectable measuring ranges: 0.0–10 mg/L, 0.5–100 mg/L, and 5–500 mg/L.
Product Features
- Direct online measurement: no manual pretreatment; probe/riser immersion for in‑situ sampling.
- High‑performance digestion: sealed high‑temperature, high‑pressure digestion (adjustable digestion time 5–120 min) speeds reactions and limits corrosive gas loss.
- Precise reagent handling: photoelectric metering for accurate, trace reagent dosing (each dose ≈1.5 mL); select valve timing and peristaltic pump under negative pressure with air buffer to protect tubing.
- Robust materials: imported PTFE transparent reagent tubing (Ø >1.5 mm) to reduce clogging and corrosion.
- Data and connectivity: touch screen, automatic residual‑reagent purge on reset/power‑on, data saved through alarms/power failures; outputs include two 4–20 mA channels plus RS232/RS485.
- Performance specs: repeatability ≤±5%, 24‑hour stability ≤±10%; minimum measurement cycle ~50 minutes; adjustable sampling interval (55–9999 min), calibration interval (1–99 days).
Product Value
- Enables continuous, automated TN monitoring to support irrigation water management and algae control decisions.
- Reduces operating costs through low reagent consumption, lower maintenance frequency, and fewer failures.
- Improves response time and regulatory compliance by providing reliable online data at discharge points, surface waters, and irrigation sources.
- Saves labor and laboratory costs by eliminating frequent manual sampling and pretreatment.
Product Advantages
- Lower failure rate and maintenance needs compared with similar instruments due to unique design and protected fluid handling.
- High dosing accuracy (photoelectric metering) overcomes peristaltic‑tube wear errors and enables precise low‑volume reagent use.
- Sealed digestion minimizes volatilization/corrosion issues common in open systems.
- Automatic safety/cleanup features (residual reagent discharge) and data retention on power loss enhance reliability.
- Backed by BOQU: independent IP, experienced development and support team, global project experience, and a quality‑and‑sustainability oriented company approach.
Application Scenarios
- Agricultural irrigation systems and reservoirs — monitor TN to manage fertilizer runoff and reduce eutrophication/algal bloom risk.
- Reuse of treated wastewater for irrigation — real‑time quality control of nutrient levels.
- Surface water monitoring — rivers, lakes and irrigation canals where nitrogen drives algae growth.
- Point‑source discharge monitoring — wastewater effluent compliance at industrial and municipal outlets.
- Aquaculture and water resource management — sites where nitrogen balance affects ecosystem health.
