Online Silica Analyzer - for Agriculture - BOQU

Product Overview

- BOQU GSGG-5089 Online Silicate (Silica) Analyzer is an industrial, continuously operating instrument for automatic measurement of dissolved silicate (SiO2) in water. It integrates automatic chemical reaction, air-mixing/photoelectric detection, graphic LCD display, data storage, and control outputs in a single rack-mounted unit. Manufactured by Shanghai Boqu Instrument Co., Ltd., it is designed for reliable 24/7 online monitoring.

Product Features

- Measurement ranges: selectable 0–20 µg/L, 0–100 µg/L, or 0–5000 µg/L with low detection limit.

- High precision and stability: accuracy ±1% F.S., repeatability ±1% F.S., drift ≤ ±1% F.S./24 h.

- Response and sampling: initial response ~12 minutes, sampling period ≈10 minutes per channel.

- Multi-channel support (1–6 channels), 4–20 mA isolated outputs, RS485 Modbus communication, and alarm relay (220 V / 1 A).

- Long-life cold monochrome light source, color LCD with charts/curves, 30-day historical curve storage, automatic calibration (programmable), maintenance-free operation except reagent replenishment.

- Practical specs: reagent consumption ~3 L/month per reagent (three reagents), power AC 220 V ~50 W, environmental and water condition limits provided.

Product Value

(for agriculture)

- Enables continuous, real-time monitoring of silicate in irrigation and nutrient solutions, helping optimize silicon fertilization and nutrient management for crop health and yield.

- Reduces dependence on time-consuming lab tests by providing instant data for rapid decision-making in greenhouse, hydroponic and field fertigation systems.

- Supports preventive maintenance of irrigation systems (preventing silica scaling and clogging), improving system uptime and reducing labour and replacement costs.

- Facilitates traceability and compliance with water quality targets in high-value crop production and agricultural research.

Product Advantages

- High sensitivity and accuracy across low-to-high concentration ranges suitable for delicate hydroponic and general irrigation applications.

- Fully integrated, user-friendly interface with graphical trends and automated calibration reduces operator workload and training needs.

- Multi-channel capability allows centralized monitoring of multiple lines or zones (e.g., several greenhouses or nutrient tanks) with independent outputs.

- Durable optical design (air-mixing/photoelectric detection + long-life light source) for stable, low-maintenance long-term operation.

- Communication and alarm functions enable easy integration into farm control systems and automated fertigation controllers.

Application Scenarios

(agriculture)

- Continuous monitoring of irrigation water quality for open-field and drip irrigation systems to prevent silica-related scaling and ensure consistent delivery.

- Hydroponics and soilless cultivation: real-time control of silicon dosing in nutrient solutions and recirculating systems.

- Greenhouse fertigation: multi-channel monitoring of several benches/tanks to optimize nutrient recipes and plant protection.

- Nurseries and seedling production: tracking dissolved silicate to support healthy root development and disease resistance.

- Agricultural research stations and fertilizer production QA: precise silicate measurement for trials, formulation control, and process monitoring.
