Precise Dissolved Oxygen Measurement for Water Quality and Process Control
Online Dissolved Oxygen Controller ST 460 Ensure accurate, real-time monitoring of dissolved oxygen (DO) levels with our versatile range of dissolved oxygen meters—essential tools for environmental testing, wastewater treatment, aquaculture, biotechnology, and laboratory research. Whether you’re assessing aquatic ecosystem health, optimizing aeration in treatment plants, or controlling fermentation processes, our DO meters deliver reliable, lab-grade results in the field or on the bench.
Advanced Technology for Consistent Accuracy
Our dissolved oxygen meters utilize either electrochemical (galvanic/polarographic) or optical (luminescence-based) sensor technology—both offering high sensitivity, fast response, and long-term stability. Optical sensors require no membrane replacement or electrolyte refills, while electrochemical probes provide proven performance at an accessible price point.
- Wide DO Range – Measures from 0.00 to 20.00 mg/L (ppm) or 0–200% saturation, suitable for freshwater, seawater, and process streams.
- Automatic Temperature & Salinity Compensation – Ensures accurate readings across varying environmental conditions.
- Barometric Pressure Correction – Built-in or manual pressure adjustment for altitude and weather-related accuracy.
- Rugged, Portable Designs – IP67-rated handheld models for field use; benchtop versions for lab precision.
- Data Logging & Connectivity – Store hundreds of readings with timestamps; export via USB or Bluetooth for reporting.
- Low Maintenance & Calibration Alerts – Intuitive prompts for zero-point or saturation calibration to maintain compliance.
Trusted for Critical Applications
From regulatory compliance (EPA, ISO 5814) to protecting fish stocks in aquaculture, accurate DO measurement is non-negotiable. Our meters support GLP/GMP standards, feature durable construction, and are designed for minimal drift—so you can trust your data, run after run.
Whether you need a simple spot-check tool or a fully traceable monitoring system, our dissolved oxygen meters offer the precision, durability, and ease of use your work demands.
Make every measurement count—with confidence in your water’s most vital parameter.
