Practical Online Nitrogen Analyzer Company

Product Overview

Note: the detailed description you provided is for the BOQU TFG-3058 Online Fluoride Analyzer. Although the product name you gave mentions “Nitrogen,” I summarized based strictly on the provided fluoride analyzer information.

Product Features

1) Product overview

Product Value

- Model: BOQU TFG-3058 Online Fluoride Analyzer — an automatic, online spectrophotometric analyzer for continuous fluoride monitoring.

Product Advantages

- Working principle: fluoride in the sample reacts with reagents (fluorine reagent and cerium nitrate in acetate buffer) to form a colored complex; the instrument detects color change and converts it to fluoride concentration.

Application Scenarios

- Key specs (high level): measuring ranges 0.00–15.00 mg/L and 0.5–50 mg/L; accuracy ±0.05 mg/L for low concentrations (≤0.5 mg/L) and ±10% above that; minimum measurement cycle ~50 minutes (digestion time adjustable 5–120 min).

- Hardware: touch-screen display, automatic flushing/resume after power or alarm reset, data retention through alarms and power loss, outputs 4–20 mA (2 channels), RS232/RS485.

2) Product features

- Precise reagent dosing: visible photoelectric metering avoids peristaltic tube wear errors; each dose ~1.5 mL to minimize reagent use.

- Select valve assembly for accurate reagent/sample timing control.

- Peristaltic pump suction under negative pressure with an air buffer to protect pump tubes from corrosion.

- Sealed high-temperature/high-pressure digestion accelerates reactions and prevents volatilization/corrosion losses typical of open systems.

- Durable reagent tubing: imported PTFE transparent hose (≥1.5 mm ID) to reduce clogging risk.

- Flexible operation: adjustable sampling interval (55–9999 min), calibration period (1–99 days), and monthly maintenance schedule.

- Robust user interface and automatic recovery functions (auto-discharge residual reactants and resume operation after reset/power-on).

3) Product value

- Reliable continuous monitoring of fluoride levels for regulatory compliance and process control.

- High sensitivity and accuracy at low fluoride concentrations support safe drinking water monitoring.

- Lower operating cost: reduced reagent consumption and lower maintenance frequency.

- Reduced risk of downtime thanks to lower failure rate design, automatic recovery, and remote analog/digital outputs for integration with control systems.

- Safer, cleaner operation via sealed digestion and corrosion-protected fluid paths.

4) Product advantages (compared to similar instruments)

- Lower failure rate and maintenance needs due to unique mechanical/design choices.

- More accurate and stable reagent dosing (photoelectric metering vs. reliance on peristaltic tube wear).

- Minimal reagent use (trace dosing ~1.5 mL), decreasing consumable costs and waste.

- Corrosion protection: negative-pressure pumping and sealed digestion minimize damage and reagent/sample volatilization.

- Reduced sample/tube clogging with larger-diameter PTFE tubing and improved fluid path design.

- Data safety: stores data during alarms and power loss; easy integration via 4–20 mA and serial communications.

5) Application scenarios

- Drinking water treatment and distribution systems (continuous fluoride compliance monitoring).

- Surface water monitoring (rivers, lakes) for environmental surveillance.

- Water quality monitoring in municipal water plants and utilities.

- Industrial process effluent monitoring where fluoride must be tracked or controlled.

- Environmental laboratories or remote online monitoring stations requiring automated, unattended fluoride measurement.
